The systems described in Table 1 have been assessed for use with a range of claddings (outside the
scope of this certificate) shown in Table 2 below which are not supplied by Kingspan Ltd but for which
performance assessments have been made in relation to use with the KBS and AFS systems.
The characteristics of The Kingframe Building and Architectural Façade Systems have been reviewed
with respect to the current Building Regulations, British and European Standards and other
publications in the United Kingdom and Ireland in January 2011. The assessment is described in the
following pages which form integral parts of this certificate and which should be read in its entirety.
CONDITIONS OF USE
0.1
The structural adequacy of the KBS and AFS systems for each use shall be assessed and
designed by Kingspan Ltd who use competent and qualified structural and design engineers
experienced in steel frame design. These structural assessments shall be site and project
specific and demonstrate that all the requirements of relevant Building Regulations have been
met. The engineer is responsible for confirming that the design is consistent with those that
have been examined by BRE Certification.
0.2
In addition to use with the KBS system, the AFS system is suitable for fixing to both hot rolled
steel and reinforced concrete multi storey framed structures. The fixing methods “to the
primary structure” shall be specified by Kingspan Ltd. The structural adequacy of these fixings
has not been assessed by BRE Certification as they form part of the project specific design.
0.3
BRE Certification has not assessed elements of structure not supplied by Kingspan Ltd, for
example main structural frames, foundations, ground floor structure and roofing structures
other than roofs formed from Kingspan joists.
Page 2 of 38
0.4
This certificate has not assessed the performance of conventional elements supplied within
the building (e.g. staircases, door sets, fittings, plumbing, drainage, mechanical or electrical
services). It is required that these satisfy all necessary Building Regulation and legislative
requirements.
0.5
Assessment has been made of the performance of walls and floors when using specific lining
and cladding systems referred to in this certificate. It is the responsibility of the constructor to
ensure that correctly specified components are installed in accordance with Kingspan Ltd’s
installation instructions.
0.6
The KBS and AFS systems shall not be used as part of external wall systems on buildings
with a floor more than 18m from the ground.
0.7
The systems are designed to be erected within a short period of time. Any structure shall be
made fully weathertight through provision of the external cladding and roof covering as soon
as reasonably practicable. Suitable protection shall be afforded to elements of construction
susceptible to damage.
0.8
The U-values of building elements not covered by this certificate shall be determined and
used with information in the certificate to demonstrate overall compliance with the
requirements for thermal performance. Where appropriate, field measurements of the building
shall be undertaken to demonstrate compliance with the requirements for airtightness.
0.9
The current policy of NHBC, as detailed in their technical standards, requires provision of a
drained cavity for light steel frame construction and precludes the use of face sealed panel
systems as cladding. Therefore some finishes specified in Table 1b of this certificate will not
be acceptable on NHBC projects.
0.10
Acoustic testing on completed constructions has demonstrated that suitably defined walls and
floors can meet the required performance standards, see section 2.5. However, precompletion testing shall be conducted where necessary to demonstrate compliance with the
Building Regulations.
0.11

Composite concrete floors
2.3.6.1 An assessment has been made of the Kingspan Multideck composite concrete flooring
system for use with the KBS system. This assessment has determined that published
Kingspan Multideck load-span tables, which include consideration of fire performance, may
be used to specify the floor details. The use of KBS walls to support the composite slab, via a
fire protected steel channel, has been assessed by BRE Certification to have no significant
influence on the fire resistance performance specified in those load-span tables.
2.3.6.2 The floor shall be designed in accordance with BS 5950-8 by appropriately qualified
engineers to individual project specification requirements to include:
•
Appropriate selection of Multideck MD – V2 profiled steel decking
•
Minimum Grade 30 concrete with maximum 10mm lightweight or normal weight
aggregate
•
Reinforcement to meet anti-crack and/or fire resistance requirements
•
Appropriate floor and/or ceiling finishes.
2.3.6.3 The connections between the floor and the KBS supporting walls shall be fire protected in
accordance with relevant Kingspan Ltd details KBS-01-U-00427 (sheets 1 and 2). An
illustration of a typical location of the fire protective board is defined as (F) in KBS-VRC-00204 on page 37 of this certificate (informative).
2.3.7
Cadeby White Limestone cladding Fire Performance
An assessment of the fire performance of a wall system with Cadeby White Limestone
cladding. This assessment was based on fire resistance tests conducted to BS EN 1364: Part
1: 1999 Fire resistance tests for non-load bearing elements. Walls. The assessment
concluded that the when the system is exposed to fire from the inside of the building it can
achieve a fire resistance of at least 90 minutes; and when the system is exposed to fire from
the outside of the building it can achieve a fire resistance of about 60 minutes. Full details of
the construction and assessment are included in BRE Global report CC 263224
2.4
Thermal performance
2.4.1
BRE has assessed the hygrothermal performance of the AFS system as detailed in this
certificate. The assessment involved calculation of the U-values of the plane building
elements (façade panels including external finish where appropriate), the risk of interstitial
condensation and checking for potential for compliance with Approved Document L1 and L2
of the Building Regulations (England and Wales), section 6 of the Building (Scotland)
Regulations, and Technical Booklet F of the Building Regulations (Northern Ireland).
2.4.2
A summary of the calculated U-values for typical systems covered by this certificate is given
in Table 5 below. The U-value calculations have been made according to the calculation
method of BS EN ISO 6946: 1997 Building Components and building elements – thermal
resistance and thermal transmittance – calculation method. Where required, improvement in
the thermal performance can be achieved by increasing the insulation thickness.

calculations for studs spaced at centres less than 600mm and/or different dry linings should be carried out in
accordance with BS/IS EN ISO 6946 and further advice should be sought from Kingspan Ltd.
2.4.3
The risk of interstitial condensation was assessed for the plane building elements of selected
facade groups. The assessed facade constructions pass the criteria in BS EN ISO
13788:2002 Hygrothermal performance of building components and building elements.
Internal surface temperature to avoid critical surface humidity and interstitial condensation.
Calculation methods for assessing the risk of interstitial condensation. Other elements of
construction such as floor and roof have not been assessed.
2.4.4
Junctions between building elements and openings have associated with them a linear
thermal transmittance that quantifies the additional heat loss and a temperature factor that
quantifies the risk of surface condensation. The factors for, and details of, junctions that have
been assessed by BRE Certification can be found at www.kingspanprofiles.com/TechnicalInformation/Kingframe-AFS-Documents.aspx clearly marked with the BRE Certification logo.
2.4.5
As detailing for each project will vary reference should be made to BS 5250:2002 Code of
