Why External Wall Insulation?
PermaRock external wall insulation systems have been
used successfully for over 25 years in the UK and the
technology for more than 40 years in Europe on social
housing applications.
With 35-45% of heat lost through the walls on ‘hard to
treat’ and solid wall homes, the application of a
PermaRock external wall insulation (EWI) system will
provide a number of positive benefits to the building
occupants:
Our systems were developed in the UK to address issues
found in post-war housing stocks, particularly for
application on to solid wall and ‘Hard To Treat’ homes
that are not able to benefit from cavity wall insulation.
PermaRock systems are suitable for application in
areas classified as having very severe exposure - i.e. the
whole of the UK.
Systems have BRE accreditation with minimum
lifetime expectancies in excess of 30 years and are now
widely used across all market sectors, both on new and
existing buildings.
Why Insulate?
There are many reasons and factors why you should
consider insulating a building and improving its thermal
performance, these include the following:
• To reduce the amount of energy consumed by
buildings and reduce fuel bills
• To reduce emissions of CO2 and other greenhouse gases
• To reduce condensation and dampness and the
associated health problems
• To increase comfort levels within the home environment
Building Regulations, Government Legislation &
Initiatives (CERT/CESP/Decent Homes/Green Deal
Strategy) may also make thermal improvements a
requirement or a more attractive improvement to
undertake.
• Lower fuel bills: The installation of an external wall
insulation system has a ‘thermal jacketing’ effect that
causes heat energy losses through the external wall to
be reduced. High levels of energy efficiency can be
achieved over other forms of insulation resulting in
savings on energy bills, especially where other measures
are not suitable (non-cavity/solid wall properties). An
average semi-detached home could typically save
£400 - £500 per year on fuel costs
(Source: Energy Savings Trust)
• A PermaRock EWI or render system protects the building
fabric from the worst excesses of the weather and
allows damp structures to dry out. As a result, the
building can expect a longer useful lifetime
• An external wall insulation system when detailed
correctly overcomes the effects of cold bridging, thereby
eliminating condensation and dampness
• The original wall construction can be used as a heat
store. This thermal mass helps to reduce temperature
fluctuations and maintains a more comfortable internal
environment
• Systems are durable and cost effective and can
improve the appearance of older buildings
• Application can take place without disruption to the
occupants and there is no reduction in interior living or
working space

- Design Considerations
PermaRock’s Area Sales Managers and Technical
Department are available to provide assistance and
advice with external wall insulation (EWI) system
specification as there are number of considerations that
could affect the choice of system and decorative finish
proposed:
• Type of Building/Wall Build-Up:
The system choice should be suitable for its application
(low-rise or high-rise) and for the wall construction type.
The building should be structurally sound to accept the
system load (a structural survey maybe required) and
where necessary, any structural and preliminary works
need to be carried out before the EWI system is
installed.
• Thermal Performance:
What is the required U-value (see pages 16 & 68 for
further details) and are there limitations to the thickness
of system which can be accommodated?
• Fire Performance:
The system should be suitable for low-rise and/or
highrise application and, where required, should
incorporate fire performance or fire-breaks to meet with
Building Regulations and BR135 requirements.
• Environmental Performance:
The system should incorporate insulation materials
which are CFC/HCFC free and which do not employ
ozone depleting chemicals in their manufacture. The
specifier may also wish to take into account any
Eco-points rating a system may have achieved through
a life cycle assessment. This process measures its
environmental impact during the systems economic life,
from the extraction of the raw materials and
components to the disposal (and recycling) of the
product at the end of a 60 year life cycle (i.e. cradle
to grave).
• Adaptations:
Roof overhang, window & door replacements, plumbing,
heating and ventilation requirements should be
considered prior to the installation of the EWI system.
• Aesthetics:
Is the desired finish and colour available and is the
decorative finish suitable for its intended location and
exposure?
• Cost:
A number of factors can have an effect on the cost of
the system including insulation type and thickness as
well as the choice of decorative finishes - PermaRock
can advise on the implications of proposed choices to
the cost of the system.
• Impact Resistance:
The decorative finish is selected primarily based on the
desired aesthetic appearance whilst also considering
the level of impact resistance necessary. Where
required, additional reinforcement can be incorporated
into the system design.

Preliminary Works & Application
Approved Applicators
Walls must be sound and dimensionally stable and
capable of withstanding the additional load imposed by
an external wall insulation system (a structural survey
may be required) and unless otherwise specified, the
system is typically installed from DPC level (insulation
below DPC floor level is also advisable), working
upwards and is normally applied (dependant on access)
from scaffold or mast climbers.
PermaRock external wall insulation systems incorporate
rigid insulation boards in thicknesses to suit individual
project requirements. Insulation boards are mechanically
fixed, with additional adhesive bonding if required, or
adhesively bonded with supplementary mechanical
fixings. After fixing, the boards are ready to receive a
PermaRock high polymer content cementitious base coat
and glass fibre alkali resistant reinforcing mesh. Corners
are reinforced with pre-formed protection profiles.
Installation of PermaRock systems is undertaken by our
nationwide network of trained and approved applicator
contractors.
All preparatory works and adaptations (i.e. rainwater
goods / waste pipes / overflow outlets / soil stacks / boiler
flues / roof overhang, etc.) are also completed before
installation. Application will occur whilst the building
occupant is insitu and disruption is minimal, however, as
part of the installation process drilling and mixing
machines will be in use whilst work progresses. Allowing
for normal weather conditions and all necessary
preliminary works, installation on a typical semi-detached
house can take between 2 – 3 weeks.
Dependant on the decorative finish, typically a second
coat of PermaRock high polymer content cementitious
bedding mortar coat will be applied along with the
chosen decorative finish.
Systems come complete with a full range of profiles,
trims and accessories to achieve weather-tight and
durable details in compliance with the principles of
robust construction.
Approved applicator personnel receive regular training
updates and are kept abreast of the latest innovations
and product developments. The performance of the
applicators is constantly monitored to ensure continuing
satisfactory performance.
PermaRock operate an Identity Card system for trained
external wall insulation site operatives. The cards are
monitored and checked by System Technicians during
routine site visits to ensure system installation is
undertaken by correct personnel and that quality
standards are maintained.
the UK. PermaRock can provide details, on a project-byproject basis, of approved applicators capable of carrying
out the installation of any PermaRock system based on a
projects size, location and programme requirements.
Many of PermaRock's applicators are of sufficient size and
calibre to undertake general building works and the full
main contractor role, providing a full package of access,
site supervision and management, and fulfilling the
requirements of Health & Safety / CDM regulations, etc.

PermaRock External Wall Insulation:
Existing Buildings
BISF Steel Frame House:
Before EWI installation
For many existing buildings, the thermal performance
of the external walls falls well below the standards
required by current Building Regulations with heat
energy losses through the walls being of an
unacceptably high level by today’s standards.
Many buildings were designed without any form of
insulation in the walls, and even those buildings with
cavity walls which have subsequently been fitted with
cavity insulation can fail to meet the stringent thermal
performance requirements of the current Building
Regulations and Decent Homes Standards. Many existing
buildings also suffer from cold bridging and the
associated problems of dampness and condensation
which can have health implications for building
occupants.
Building owners are also faced with ever increasing
costs for heating and maintenance whilst at the same
time being asked to reduce energy consumption in
support of global efforts to reduce CO2 and other
greenhouse gas emissions.
BISF Steel Frame House:
After EWI installation
Reducing heat energy losses through the external
envelope and eliminating problems associated with
condensation and dampness is a key issue for both social
housing and for commercial redevelopment, for high-rise
and low-rise, traditional and non-traditional forms of
construction.
Complete remodelling of the building façade is also
possible with PermaRock. The wide range of decorative
finishes and effects that are available with PermaRock
systems provides the designer or specifier with the
means of creating interesting and aesthetically pleasing
façades that either compliment the original style or
which can create a whole new impression.
PermaRock systems are available for all types of
construction, including solid wall or cavity wall, concrete,
steel or timber frame, dense and no-fines concrete, brick
and stone, rendered, metal clad, tile clad or timber clad
structures. PermaRock systems have been designed for
use on high and low rise buildings, for traditional and
non-traditional forms of construction, including many
pre-cast reinforced concrete (PRC) types, in exposure
conditions ranging from sheltered to very severe.
10
PermaRock systems can achieve very high standards of
thermal insulation, not only up to current Building
Regulations requirements for new buildings but also
beyond predicted future energy-saving and CO2 reduction requirements: PermaRock systems can be
designed to meet or exceed any future reduction in
Uvalues that may be imposed.
Please be aware external wall insulation changes the
appearance of a building so planning permission may be
required. This is particularly relevant in conservation
areas.
11
03
Low-Rise Housing
Solid or cavity wall. Concrete, timber or steel frame.
Houses, bungalows or flats. Traditional or nontraditional
build. PermaRock offers complete technical
solutions to meet the external wall insulation
requirements of all forms of low-rise housing.
With traditional solid wall or cavity wall construction,
PermaRock systems can provide all levels of
rejuvenation from a simple aesthetic uplift, using a high
performance exterior render system, to full thermal
performance improvements, elimination of cold bridging
and condensation using a fully accredited external wall
insulation system (EWI).
A PermaRock EWI system provides immediate benefits
in terms of heat loss reductions and savings in heat
energy costs. The system protects the building fabric,
extending the useful life of the structure, and offers the
opportunity for improving the appearance using any of
our range of low maintenance exterior finishes and
effects.
PermaRock systems can be designed to deliver U-values
that are considerably better than current Building
Regulations requirements, and systems can be designed
for application to walls that have already been treated
with cavity insulation, to provide further improvements in
thermal performance whilst shifting the structural
dewpoint to the outside, thereby eliminating the risk of
interstitial condensation.
Unity Non-Trad House:
After EWI Refurbishment
‘Hard To Treat’ Homes - Solid Wall &
Non-Traditional Housing
PermaRock systems have been used extensively across
the UK, from the Shetland Islands and Western Isles in
the North, to the extremities of Cornwall in the far South
West, in urban and rural environments and in exposed
and sheltered locations.
PermaRock systems are designed to provide thermal
and aesthetic improvements to all forms of housing but
are especially suited for application onto ‘Hard To Treat’
homes, such as solid wall and non-traditional housing or
where cavity wall insulation is not suitable or possible.
PermaRock external wall insulation (EWI) systems
provide a thermal jacketing effect that stabilises the
structure by reducing thermal movements whilst
protecting the building fabric from water and
weathering, extending the buildings useful life by a
minimum of 30 years whilst enhancing comfort levels by
eliminating cold bridging, dampness and condensation.
The application of a PermaRock EWI system will raise
the temperature of the building fabric, reducing
interstitial condensation and dampness, allowing drying
out to occur. Reduction in the moisture content of
concrete reduces reinforcement corrosion and can
therefore prolong the life of the structure - a particularly
important effect with PRC (prefabricated reinforced
concrete) buildings.
Non-Traditional Housing
PermaRock is able to offer solutions for many PRC
house types, as well as for other non-traditional or
system built types, including the following:

High-Rise Buildings
High-rise buildings present a number of interesting
technical challenges for the external wall insulation
system designer.
In addition to experiencing greater structural movement
and higher wind suction forces than low-rise buildings,
high-rise structures are riskier in terms of fire
propagation, and are less likely to see regular exterior
maintenance than their low rise counterparts.
The installation of an external wall insulation system to a
high rise building is a longer process than with low-rise
buildings, and the various elements forming the system
may therefore be exposed for some time before the final
rendered surface is achieved.
It is important that façade systems for high-rise
structures are designed with specific regard to these
particular technical requirements.
PermaRock’s track record with high-rise is second to
none, and our award winning systems have been
designed to provide excellent thermal performance as
well as total resistance to driving rain and high negative
wind pressures. PermaRock systems are tough and
durable, will withstand extremes of temperature and
have very low maintenance requirements.
But more than just providing systems that fulfil the
technical requirements of high-rise buildings,
PermaRock offers the widest choice of decorative
finishes and effects giving the designer freedom of
expression to create interesting and pleasing façades.
With high-rise buildings, the use of contrasting colour
and texture enables the scale of buildings to be
accentuated or diminished. Additional relief modelling,
using extra layers of insulation or preformed insulation
sections can be used to 'break up' the façade or to
introduce curves into otherwise flat elevations.
PermaRock’s products and systems provide a totally
flexible approach to rejuvenating high-rise buildings,
combining good looks with practicality, satisfying the
needs of the building owner and the occupants, the
specifier and the installer.
The PermaRock Mineral Fibre and PermaRock Lamella
Systems are fire-safe during all phases of installation,
not only after the final coat of render has been applied
and are recommended for multi-storey buildings where
optimum performance in relation to fire is paramount.
PermaRock systems can be applied to almost any
substrate type, including brick, dense and no-fines
concrete, blockwork, solid wall, cavity wall or panel (fair
faced, exposed aggregate or ribbed) constructions.
Where the building façade requires remodelling,
perhaps by the extension of the external walls to
enclose balconies using a lightweight metal frame,
timber frame, or SIPS construction method, PermaRock
systems still provide the optimum overcladding
solution.
PermaRock systems are lightweight and easy to install
from a traditional scaffold or from mast climbers.
Installation is carried out by trained, specialist
applicators monitored by PermaRock.
The issue of fire safety is particularly important with
high-rise buildings. PermaRock has a range of systems
that offer the opportunity of CFC/HCFC free insulation
that meets the requirements of Building Regulations
and BS 8414 and can be designed for use on high-rise
buildings without the need for fire breaks.

Case Studies
Award Winning Solid Wall Insulation:
Solar House, Whitecross Estate, London
Innovative Solid Wall Insulation:
Grove Cottage, Portfield Street, Hereford
Client: Peabody Trust
Client: A. Simmonds
Specifier: Peabody Design Group
Substrate: Solid Brickwork 9” & 13”
System: PermaRock 90 mm Mineral Fibre External
Wall Insulation System
Wall U-Value Achieved: 0.35 W/m²K
System Finish: PermaRock Acrylic K 1.5 mm Finish
Solar House, prior to its transformation, was a
traditionally built, flat roofed, 4 storey building with
poor thermal efficiency typical of its type and period.
The client, Peabody Trust, saw the refurbishment of
the block, utilising the PermaRock Mineral Fibre
External Wall Insulation System, along with the
introduction of solar technology as an ideal solution to
its commitment to its sustainable development of its
housing stock.
PermaRock supplied a 90 mm mineral fibre insulated
render system to achieve a U-value of approximately 0.35
W/m²K to the brick wall areas.
Pre EWI installation
18
In addition to the use of external wall insulation (EWI),
the client also incorporated banks of photovoltaic panels
in the new roof, which provide electricity, heating and
lighting for its residents and along with the EWI has
resulted in a reduction in carbon emissions.
The application of the insulation on the outer wall also
ensured that maximum technical benefit was gained
from using the insulation. Interstitial condensation in the
wall structure was eradicated as the dewpoint was
moved to the outside of the building, whilst a mineral
fibre based system was chosen for its fire resistant
properties.
Aesthetically, the use of PermaRock’s K 1.5mm textured
render, in two contrasting colours, complemented the
timber cladding giving the refurbished block the
appearance of a newly built residential development.
The combination of the insulation to the external wall
envelope and solar panels to the roof makes this project
one of the most energy efficient refurbishment schemes
on a residential block in recent years.
Post EWI installation
Specifier: Simmonds Mills Architects
Substrate: Solid Brickwork
System: PermaRock 250 mm EPS-Premium External
System Finish: PermaRock Silicone K 1.5 mm Finish
PermaRock’s EPS-Premium external wall insulation (EWI)
system was installed as part of a number of energy
efficient retrofitted measures to a detached 1869
Victorian house in Hereford to help contribute towards
creating a low-energy, Passivhaus standard, building.
This set extremely challenging targets for improving the
thermal performance of the building fabric through high
levels of insulation, ‘thermal bridge-free’ junctions
between walls, floors and roofs etc and aiming for a very
airtight building envelope of 0.75m³/m²hr @50 Pa in the
final test 0.97m³/m²hr @50 Pa was actually achieved an excellent result: 2010 Building Regulations require
an airtight building envelope of 10.00m³/m²hr @50 Pa.
Arguably the biggest contributor in achieving the required
standards was the use of the PermaRock EPS-Premium
external wall insulation system, which incorporated 250
mm of high performance expanded polystyrene
insulation, and helped bring the U-value of the external
solid brick walls down to 0.11W/m²K.
Prior to the recently completed works, the solid brick
cottage had difficulties in achieving and maintaining an
even temperature in such a poorly insulated and
draughty house and the expenditure of all this energy
never resulted in a healthy or thermally comfortable
environment. With this in mind the owners decided that
the time had come for a radical improvement to the
insulation and energy standards of the house. To meet
their own expectations, a successful outcome for the
project would result in whole house CO2 emissions for
heat and power being reduced by approximately 80 - 85%
compared, to the average measured performance of a
typical UK house of the same size.
The adhesively bonded and mechanically fixed system
had to overcome a number of issues during design stage
to enable Carbonlite/Passivhaus targets to be made
possible. As well as having to be ‘air-tight’ and produce
thermal bridge-free junctions, the incorporation of fixings
(normally plastic or metal) which penetrate the insulation
layer, would result in a series of point repeating thermal
bridges. With this in mind, special thermodowel fixings
(Ã-value of no more than 0.002W/K) were utilised as part
of the system and enabled the U-value and heating
demand of the building not to be increased.
Work began on a design that applied low-energy,
low-carbon ‘design rules of thumb’ and it was hoped that
a energy demand of no more than 22k Wh/m².yr would
be possible.
The end result is an ‘exemplar’ project in terms of the
energy and thermal performance which can be
achieved through retrofitted measures.
Aesthetically, PermaRock’s Silicone K1.5 mm Finish
throughcoloured render was used.

Case Studies
Award Winning Non-Traditional Housing Refurbishment:
BISF Houses, Shirehampton, Bristol
Client: Bristol City Council
Specifier: Bristol City Council
Substrate: BISF Steel Frame with plywood sheathing
System Finish: PermaRock Acrylic K 1.5 mm & Brick Effect
Render Finishes
Following a structural survey the consulting engineers
advised the client that the best solution to increase the
properties useful lifetime and thermal performance was
to overclad the houses with an external wall insulation
system.
Technically, the properties could not be directly overclad
with a ewi system and the existing cladding had to be
removed and replaced with 18 mm exterior grade
plywood to create a surface suitable for the application of
the PermaRock external wall insulation system.
The incorporation of 80 mm of fire-safe mineral fibre
insulation within system enabled the required U-value to
be achieved and the use of PermaRock’s Brick Effect
Render (ground floor) & K 1.5 mm (first floor) decorative
finishes helped achieve the upgraded aesthetic
appearance which was being sought.
Various other improvements (new windows, canopies,
downpipes gutters) were also undertaken prior to or at
the same time as the external wall insulation application
to upgrade the properties to a ‘Decent Homes Standard’.
The client chose to install a PermaRock mineral fibre
external wall insulation (ewi) system which not only
protected the existing building fabric but also enabled the
thermal performance of the properties to be brought into
line with Building Regulations at the time (0.35 W/m²K).
A further benefit from the application was that it allowed
the client to give the properties a more ‘traditional’
aesthetic look

Award Winning Non-Traditional Housing Refurbishment:
Steane Houses, Bournemouth
Client: Bournemouth Borough Council
Specifier: Curtins Consulting
Substrate: PRC Panels with plywood sheathing
System Finish: PermaRock Acrylic K 1.5 mm and Brick
Effect Render Finishes
After assessing the structural integrity of the properties
the consulting engineers decided the best approach to
modernising the 50 dwellings was to apply a
PermaRock external wall insulation system.
The system would not only improve the aesthetics and
thermal performance of the dwellings, it would also
extend the life of the properties by a minimum of 30
years, a key concern for the client.
Prior to the installation of the system, the existing PRC
panels were removed, replaced with 18mm plywood and
the existing steel frame was reinforced with a timber
frame. These measures increased the load bearing
properties of the walls to accommodate the external wall
insulation system as the existing PRC panels were both
cracked and corroded.
Through the installation of a PermaRock 70mm mineral
fibre external wall insulation system (where the tenants
remained insitu), the external wall U-values were brought
into line with current building regulations and provided
the concrete panel houses with a more traditional look.
PermaRock’s white acrylic through-coloured render
was applied to the upper floors and PermaRock brick
effect render to the lower floors.
The client was so pleased with the results that
PermaRock’s external wall insulation systems have been
utilised on further non-traditional house types in the area.

Award Winning High-Rise Refurbishment:
High-Rise Blocks, Glasgow
Client: Glasgow Housing Association
Specifier: Glasgow Housing Association
& Wates Living Space
Substrate: Large Concrete Panels (LPC)
and No-Fines Concrete
System Finish: PermaRock Acrylic K 1.5 mm Finish
A recent and on-going example of how PermaRock
External Wall Insulation has improved energy efficiency
and completely transformed the aesthetics of
multi-storey high rise homes is demonstrated by the
refurbishment programme being undertaken by Glasgow
Housing Association (GHA) in conjunction with Wates
Living Space.
In excess of 40 towerblocks are either on site or
completed to date, transforming what were typical
rectangular concrete towers into an exciting new
skyline. This constitutes one of the UK’s largest ever
refurbishment programmes on multi-storey blocks, with
100 high-rise blocks being given a facelift over the
coming years.
In putting together a performance specification for the
over-cladding systems for the GHA’s multi-storey
residential blocks, careful consideration was given not
only to the thermal performance requirements, in
terms of improvements in the building envelope Uvalue,
but also to fire resistance, resistance to impact,
resistance to water penetration and wind suction
forces. How the system installation could best be
undertaken alongside a concurrent window
replacement program was also taken into account.
GHA, working closely with Wates Living Space, fully
appreciated that the external envelopes of multi-storey,
high rise buildings experience a wide range of
unfavourable influences, such as extremes of
temperature, wind, rain, fog, sunlight, atmospheric
pollutants and the possibility of organic infestation from
mildew, mould and algae.
22
There was also much thought given to the fire
performance requirements for the external cladding
system. Previous fires in high rise blocks at Knowsley
Heights in 1991 and at Garnock Court, Irvine in 1999 had
prompted revisions to the guidance on performance
requirements for external cladding systems on multistorey buildings, and the GHA external cladding
programme required that the cladding system be fully
compliant with the Scottish Building Standards and tested
in compliance with BS 8414-Part1: 2002 ‘Test method for
non-loadbearing external cladding systems applied to the
face of the building’ (Assessed in accordance with BR135).
After a rigorous assessment of systems available in the
UK, and after evaluating the technical support available
from the system designers, as well as the experience and
competencies of the systems approved installers, the
PermaRock external wall insulation system was selected
as a system that could meet all of the client’s
requirements and comply with BS 8414-Part1: 2002.
The results to date at Glasgow have met with approval
from all quarters, and already the occupants of the blocks
have noticed an improvement in internal comfort levels,
as well as being delighted with the improvements in the
appearance of their homes.
Ian Morrison, of Whiteinch & Scotstoun HA (part of
Glasgow HA), comments ‘With no investment in the
external fabric of the building since the blocks were
erected, tenants were delighted with the new windows
and external cladding (PermaRock external wall
insulation) works carried out. Tenants have generally
expressed their relief that the buildings are now warm
and can be heated more cost effectively, while the
outward appearance of the block is now considered to be
attractive. All at Whiteinch LHO were glad that working
with our colleagues in the GHA could see these important
improvements delivered to tenants’.
The regeneration of the Glasgow high rise tower blocks
clearly demonstrates how social housing can utilise the
full capabilities of EWI. Not only are the basic technical
requirements of structural protection and heat energy
saving achieved, but the innovative use of bold
colourful design indicates a level of excellence in a
social housing refurbishment scheme.

CERT & CESP Supportive Funding
PermaRock’s range of products and services is
complimented by the ability to facilitate funding / grant
support under the Carbon Emissions Reduction Target
(CERT) and Community Energy Savings Programme
(CESP) initiatives for residential external wall insulation
(solid wall insulation) refurbishment projects.
PermaRock, part of energy efficiency specialists Eaga
plc is able to source funding contributions for the
PermaRock external wall insulation element of a
contract, subject to qualifying criteria.
Carbon Emissions Reduction
Target (CERT)
What is CERT?
CERT - which came into effect on 1 April 2008 and will
run until 2012 - is an obligation introduced by the
Government on energy suppliers to achieve targets for
promoting reductions in carbon emissions in the
household sector and combating fuel poverty.
CERT will maintain a focus on vulnerable consumers
and now includes new innovative and flexible
approaches to energy efficiency, including PermaRock
external wall insulation systems.
What information is required?
We would be pleased to investigate the opportunity to
facilitate the potential provision of CERT funding for
PermaRock External Wall Insulation schemes. To
enable us to progress matters, we would need several
items of information to calculate estimated values of
any funding that might be available.
The information required would be primarily:
1. The number of dwellings forming the scheme.
2. The type or types of dwellings (eg Flats, Semidetached,
Terraced, etc).
3. Number of bedrooms in each type of dwelling.
4. The Postal Codes for the dwellings.
5. The existing and target U-Value in each case (note that
PermaRock can assist with any necessary U-Value
calculations that may be required if they haven’t already
been prepared).
6. Current fuel type.
24
Furthermore, to qualify for any of the maximum levels of
funding available, the social housing provider is
required to sign a declaration (provided by us) stating
that at least 70% of the homes are in “Priority Group”
status, e.g. the homes are occupied by persons on
qualifying benefits.
CESP – Key Features
• CESP will promote a whole house, house-by-house,
street-by-street approach.
Please contact PermaRock for further information on
CERT funding.
• It is estimated that up to 100 schemes will be funded,
benefiting around 90,000 homes across Great Britain.
Community Energy Savings
Programme (CESP)
• It will focus on low income areas.
What is CESP?
CESP is an initiative designed to help people to reduce
their fuel bills and energy demand which aims to deliver
around £350m of energy efficiency packages between
autumn 2009 and December 2012.
The programme has been developed to further encourage
the use of innovative measures like external wall
insulation, microgeneration, energy saving appliances and
real time displays and aims to promote a ‘whole-house
approach’ of energy reduction measures.
CESP will be delivered through the development of
community-based partnerships (involving local
authorities) along with suppliers and generators.
Thermal image post EWI installation
• It will be delivered through the development of
community-based partnerships involving Local
Authorities.
The following measures are included within CESP:
External wall insulation
Cavity wall insulation
Loft insulation
Loft insulation
Internal wall insulation to solid wall housing
Fuel switching
Heating controls – upgrade with new heat system
Community heating meters
Existing community heat to CHP

Air source heat pump
Ground source heat pumps
Micro wind (1 kWp, 1% LF)
Mini-wind 5 kW, 20% LF
Micro Hydro (0.7kWp, 50% LF)
Photovoltaic panels (2.5 kWp)
mCHP (revised)
Replacing old boiler (65% by 88.3%)
Home Energy Advice (HEA)
Underfloor insulation
Glazing E to C rated
Flat roof insulation (whole house)
Draughtproofing (ie not with glazing)
• Under CESP, external wall insulation gets a CO2
lifetime savings ‘uplift’ bonus of 300%, making it as cost
effective a measure per installation as both cavity and
loft insulation in terms of kg CO2 score per £ spent.
Incentives will also be given to encourage the
whole-house approach, providing a ‘bonus’ for the
delivery of multiple energy efficiency measures taken
within the same property and to multiple properties
within the same targeted area.
Which areas qualify?
It is proposed that CESP should target those areas of
Great Britain that have significant levels of low income
households. It is these areas that have the most dense
concentration of households in need of assistance, and
where energy efficiency improvements should have the
greatest impact on fuel bills whilst also delivering
carbon savings.
The Government concluded that the use of Indices of
Multiple Deprivation (IMD) would identify the most
suitable areas for CESP.
The Government proposes that SOAs (Super Output
Areas) or Data Zones eligible for a CESP scheme must
be within the lowest 10% income decile in England
and the 15% most income deprived areas in Scotland
and Wales, based on comparable level of income
deprivation.
PermaRock, in conjunction with our parent
company, Eaga plc, (and Eaga’s partnerships
with the CESP electricity generators and energy
providers) can check potential eligibility on
postcode verification, though please note
eligibility does not automatically qualify for
funding provision.

Systems Overview
External Wall Insulation & Render Systems
PermaRock offers a range of high quality products and
systems that enable existing buildings to be refurbished
or remodelled to improve both the thermal performance
and to enhance the visual appearance.
PermaRock’s façade products are equally suitable for
high and low rise schemes and in sheltered or exposed
situations.
Technically, PermaRock systems insulate and reduce
temperature variations within the structure, creating a
stable internal environment and achieving the dual
goals of maximising thermal performance and saving
interior room space. They also reduce structural
movement and protect, waterproof and preserve the
fabric of the building.
Aesthetically, PermaRock systems are complimented
by an extensive range of decorative finishes including
acrylic, silicone and mineral textured renders, brick and
stone finishes, traditional spar dash aggregate finishes
as well as architectural profiles and waterproof coatings
which can dramatically improve the visual appearance
of a building.
The following groupings outline the principal brand
ranges offered by PermaRock.
External Wall Insulation Systems
PermaRock’s range of render protected external
insulation systems are designed to provide significant
improvements in the thermal performance of buildings
in both new-build and refurbishment applications.
PermaRock Phenolic System
The PermaRock Phenolic System is a high thermal
resistance, low-profile rigid phenolic foam insulation
board system. The high thermal resistivity of phenolic
foam insulation enables a high level of thermal
performance to be achieved for thin sections of
insulation and the system is extremely versatile. It is
suitable for application onto existing buildings, both
high-rise and low-rise, and for most construction types
including solid and cavity wall construction, timber and
metal frame.
On multi-storey buildings Phenolic EWI systems may
require the incorporation of fire breaks in accordance with
BRE Defect Action Sheet 131 and BRE 135-Second Edition.
PermaRock EPS / EPS-Premium Systems
The PermaRock EPS and EPS-Premium Systems are
lightweight, low density systems employing expanded
polystyrene insulation. The low density of the system
makes it especially suitable for situations where low
imposed loads are critical and is suitable for most
construction types on multi-storey buildings. EPS
systems may require the incorporation of fire breaks in
accordance with BRE Defect Action Sheet 131 and BRE
135-Second Edition.
EPS-Premium is a low conductivity EPS insulant which
is particularly suited for super-insulated buildings.
Exterior Render Systems
A range of high performance exterior renders that offer
levels of weatherproofing and crack resistance
unmatched by conventional cement-based render
technology.
PermaRend System
PermaRend is the leading brand of high impact resistant,
polymer-modified cementitious renders. The
basic PermaRend system is a two coat, thin render
system (up to 5 mm per layer) that provides a tough,
durable, lightweight and flexible alternative to
traditional sand-cement renders. In addition to being
highly resistant to impact damage, PermaRend renders
are weatherproof, waterproof and water vapour
permeable, allowing structures to breathe.
PermaRend renders can be decoratively finished in any
of PermaRock's extensive range of acrylic, silicone or
silicate renders / plasters, mineral aggregate renders,
silicone paints, stone chip coatings as well as with tile
finishes and brick and stone effects.
PermaRend Scratch Render is a high quality textured
render based on natural limestone sand that can be
used to provide a naturally textured ‘scraped’ finish or to
create traditional stone effects including rustication,
ashlar and simulated blockwork. Scratch Render is
available in a range of natural shades and can be
produced in special colours to order, subject to
minimum order requirements.
PermaRock’s range of systems for the refurbishment
sector are based on three key insulation types and
include:
PermaRock Mineral Fibre System
The PermaRock Mineral Fibre External Wall Insulation
System incorporates fire-safe mineral fibre insulation
boards. The system is extremely versatile and is suitable
for use on existing buildings, both high-rise and lowrise,
and for all construction types including solid and
cavity wall construction, timber and metal frame, and
non-traditional house types. The system is particularly
suited to residential buildings (especially high-rise) and
public buildings where the highest levels of fire
resistance and non-combustibility are required and
where the added acoustic noise reduction properties of
mineral fibre insulation are of benefit.

PermaRend Exterior Render System
Design & Application
PermaRend Exterior Render System
PermaRock offers the specifier a range of high
performance specialist renders for new build
applications and for refurbishment projects which are
designed to meet the requirements of all traditional and
modern forms of construction.
PermaRend is the leading brand of high impact-resistant,
polymer-modified cementitious renders. The basic
PermaRend system is a one, two or three coat, thin render
system that provides a tough and durable, lightweight
and flexible alternative to traditional sand-cement
renders.
PermaRend is a high impact-resistant, polymermodified,
cement-based render containing performance
improvers. PermaRend is designed to withstand water
penetration whilst allowing water vapour diffusion, and is
suitable for geographical areas including those classified
as having very severe exposure to wind driven rain (BS
5628: Part 3 and BS 8104).
PermaRend Scratch Render is a silicone based thick coat
render with a scraped or scratch textured surface that is
also suitable for the creation of simulated blockwork,
ashlar detailing, etc.
The range of products and systems available from
PermaRock provides the specifier with individually
tailored solutions that satisfy both the technical
requirements of the substrate and the aesthetic
requirements of the client.
All of the products described provide effective resistance
against water penetration whilst allowing the passage of
water vapour, allowing walls to ‘breathe’.
The incorporation of reinforcing mesh into systems
provides additional resilience and resistance to cracking,
and the use of mechanical fixing methods enables these
products to be applied over existing render or painted
surfaces where the reliance on an adhesive bond alone
would be insufficient to guarantee performance.
PermaRend systems are suitable for application onto
new or existing brickwork, blockwork, dense and nofines
concrete.
PermaRend systems incorporating a lightweight
reinforcement and mechanical fixings can be applied
over existing render surfaces.
PermaRend renders exhibit superb adhesion and ease of
application by trowel or machine. PermaRend renders can
be decoratively finished in any of PermaRock's extensive
range of acrylic, silicone or silicate renders / plasters,
mineral aggregate renders, silicone paints, stone chip
coatings as well as with tile finishes and brick or stone
effects.
Supplied prepacked as a dry powder premix, PermaRend
requires only the addition of clean water on site. The
mixed render is applied by machine or trowel.
PermaRend is suitable for all masonry and mineral
substrates. However, surfaces should be of a good
standard, ideally of fair-faced quality, and true to line,
level and plumbness to avoid the need for preliminary
levelling or dubbing out at extra cost.
For application to existing masonry surfaces, the
PermaRend system is enhanced by the incorporation of
reinforcing mesh giving improved resistance to structural
movement and providing a higher level of tensile
strength.
PermaRend Scratch Render is weatherproof and
breathable, and incorporates special additives that confer
water repellency to the surface, ensuring excellent self
cleaning and resistance to dirt pick-up.
In addition to the standard range of colours, described in
our decorative finishes section, PermaRend Scratch
render can be manufactured to customers individual
shade requirements, subject to minimum order
restrictions and the limitations of natural mineral
pigmentation processes.
PermaRend Exterior Scratch System
On existing rendered surfaces or old surfaces that are
weak or friable, mechanical dowel fixings are utilised
through the reinforcing mesh to enhance the integrity of
the system and to give a failsafe bond to the underlying
substrate.

All PermaRend systems come complete with a fully
comprehensive set of corner and edge protection profiles
and trims, in stainless steel, polyester powder coated
aluminium or pvc, as well as with sealing strips, mastics
and tapes to enable robust and weathertight detailing to
be achieved at windows, doors and abutments.

Environmental Profiling
Environmental Profiling
Ecopoints
Greener Supply And Recycling
In recent years there has been an increasing interest on
the part of the specifier to understand more about the
sustainability of building materials and the
environmental impacts of products and materials
utilised in the built environment.
To improve the usefulness of the environmental data
and make it easier to understand, the BRE developed
Ecopoints ratings – a method of ranking and scoring
different environmental impacts.
PermaRock has an ongoing programme of waste
management and reduction initiatives to minimise waste
as well as providing the opportunity of recycling of
system components. Examples of key benefits to using
PermaRock systems are:
Using methodology developed by the BRE (Building
Research Establishment) and BERR (The Department
for Business, Enterprise and Regulatory Reform),
PermaRock commissioned third-party whole Life Cycle
Assessments (LCA) on two of its key external wall
insulation systems. The LCA measures the
environmental impacts of the systems during their
economic life, from the extraction of the raw materials
and components to the disposal of the product at the
end of a 60 year life cycle (i.e. cradle to grave).
The environmental impact is determined by 12
categories, including Climate Change, Acid Depletion,
Ozone Depletion, Pollution to Air, Pollution to Water,
Mineral Extraction and Waste Disposal. The data
obtained from the LCA is then analysed and weighted,
using the BRE methodologies, and an Ecopoints rating
for each system has been established.
The lower the Ecopoints score, the lower the
environmental impact. The results achieved by
PermaRock are very impressive, estimated Ecopoints
scores of 0.10 per m2 (1) and 0.15 per m2 (1) on
PermaRock’s Mineral Fibre External Wall Insulation
System and Phenolic External Wall Insulation Systems
respectively were achieved.
Such extremely low Ecopoints scores reflect the
extensive work that PermaRock has put in to
environmentally engineering its products, including
reducing the energy costs associated with sourcing and
transporting raw materials, manufacturing the
products themselves, and delivering the products to
construction sites throughout the UK. Significantly,
PermaRock’s drive towards the incorporation of
recycled content into its products has also had a
beneficial impact on the Ecopoints score.
To put the results into context, assessments have also
been made on other construction products: For
example a traditional brick cavity wall construction
achieves a score of 0.48 per m2.
• Greener Supply: Ongoing efforts are being made to
reduce packaging waste. PermaRock are also looking at
other in-house initiatives to reduce waste for raw
materials and recycling as well as liaising with installers
and project teams to produce improved workable
solutions.
• Insulation: Insulation boards are CFC
(chlorofluorocarbons) and HCFC
(hydrochlorofluorocarbons) free and they have zero
ozone depletion potential (zero-ODP) and/or zero global
warming potential (GWP).
• Recycling: Recycling of certain insulation materials is
now available.
• Energy Saving Trust Approved Products: PermaRock
systems are also listed on the EST site,
www.energysavingtrust.org.uk, confirming that
PermaRock systems are amongst the most energy
efficient in their category.
(1) PermaRock systems have been externally assessed using the
environmental profile methods prescribed by the BRE 1999 and 2000 &
likely Eco points calculated as per the BRE publication of 2001

PermaRock Clean Concept Technology
PermaRock Nano-Quartz Technology
PermaRock have addressed the long standing problem of
maintaining clean facades to ensure that exterior
surfaces retain their colour and cleanliness better
throughout the lifetime of the façade system. Through
Clean Concept® research, nano-technology has been
adopted into our silicone based through coloured renders
which reduce the tendency of dirt particles to adhere to
surfaces. The technology also introduces a
photo-catalytic effect into the material, resulting in the
breakdown of dirt particles into tiny fragments which are
readily carried away when rainwater washes the surface.
Surfaces treated with Clean Concept® materials offer fast
drying after rainfall, and maintain a clean, fresh surface
appearance for longer.
Taking Clean Concept to the next level, PermaRock has
introduced Nano-Quartz technology into their range of
ThermoSan-NQG through-coloured renders and exterior
façade coatings to offer the latest in façade technology
for unbeatable results.
Nano-Quartz products, the next generation in ‘clean’
renders, provides even greater repellency against water
and further resistance to algae growth than ever before,
keeping surfaces even cleaner and brighter for longer. For
further information on this exciting new technology
please visit www.permarock.com

High Performance Exterior Coatings
PermaRock’s range of coatings for building façades and
interiors provides further possibilities for creative flair,
and enables existing coloured render surfaces to be
uplifted and provided with a new life. PermaRock actively
promotes the use of environmentally sound coatings many are completely solvent-free, emissions-free and
low odour, meeting and surpassing increasingly stringent
environmental requirements for protective and
decorative coatings.
Exterior coatings are available in an extensive range of
standard colours, from the Façade A1 colour range. In
addition, many of these products can be supplied in
shades from other colour collections, such as BS4800
and RAL.
Amphisilan Façade Coating
Amphisilan is a high performance silicone based coating
for exterior façades. Amphisilan combines the advantages
of synthetic resin dispersion coatings with those of the
classic mineral paints. The vehicle has a mineral basic
structural formula that is non film-forming and highly
permeable to water vapour and carbon dioxide.
These properties result in a coating that gives superior
breathability, water repellency and excellent resistance to
dirt pick-up and that is highly suited for application onto
exterior render and plaster surfaces, mineral substrates, as
well as for coating existing, sound silicate paints, flat
synthetic resin dispersion coatings and intact EWI systems.
Amphisilan is available in a wide range of colour shades
from the A1 colour system and now also incorporates
Nano-Quartz technology for outstanding resistance to dirt.

To make full and best use of the breadth of services
available from PermaRock it is recommended that
PermaRock are engaged early on in the project.
Early involvement means that attention can be focused
on achieving the specific project objectives and
specifications can be prepared that are closely tailored to
the individual project requirements.
This process will provide opportunities for reductions in
costs associated with time, materials and material waste
whilst at the same time maximising value for money and
maintaining a high quality standard.
U-value Calculations
In order to demonstrate that wall constructions comply
with the requirements of the Building Regulations for the
conservation of Fuel and Power, namely, approved
Documents L1 (dwellings) and L2 (other buildings) for
England & Wales, and Technical Standards Part J for
Scotland, PermaRock is able to provide U-values
calculated in accordance with the Combined Method
procedures of BS EN ISO 6946: 1997 based on wall
construction information provided by the specifier.
For constructions that cannot be readily handled by the
methods in BS EN ISO 6946: 1997, U-values may be
calculated by numerical analysis. In some cases
correction factors for linear thermal transmittance of
junctions can be provided.
PermaRock also provides, alongside each U-value
calculation, an assessment of condensation risk.
Internal and external environmental conditions can be
adjusted to meet specific building use criteria in order for
accurate assessments of condensation risk to be
provided, therefore tailoring the system accordingly.
