R-Values
What is R-Value?
R-Value is the measurement of the insulation's ability
to restrict heat flow. The higher the R-Value, the more
insulating power it provides. Batt insulation works by
restricting the air movement in the insulation.
What is the difference between stated
R-Value and effective R-Value?
Stated R-Value tests measure only thermal resistance.
It does not take into account factors such as:
Air infiltration due to leakage through gaps
Permeability of system components
 Thermal mass of components
 Thermal bridging across the building envelope

Government recommended R-Values
by climate zone
The International Code Council (ICC) publishes the
International Energy Conservation Code (IECC),
which recommends specific thermal performance
requirements.
The U.S. Department of Energy (DOE) bases its R-Value
recommendations for existing homes on specific
heating and cooling needs and the cost of energy across
the country and ZIP code. The R-Values recommended
by DOE exceed those required by most building codes.

While the stated or nominal R-Value of an insulation
product is an indicator of the material's thermal
resistance, the effective thermal resistance accounts
for the structural elements that bypass the insulation.
In real-world performance, the installation of
ROXUL COMFORTBOARD™ IS as the exterior sheathing
and ROXUL COMFORTBATT® as the wall cavity
insulation results in a building envelope that is both
resilient to moisture problems and effective at keeping
the heat in.
What’s more, ROXUL insulation does not absorb water
or hold moisture. It will not sag or lose its shape, and
will retain its R-Value. So, the R-Value installed today
will be the same for years to come.

ASHRAE map of climate zones
®
Every rating agency has its own maps that divide
regions into thermal or climate zones to tailor
codes and standards to what is appropriate for
that particular region.

®
While most attics are insulated,
over time, insulation settles or
compacts, reducing its R-Value.
How to determine an attic’s insulation R-Value
The attic is one of the easiest and most important areas
of a home to insulate.
The DOE recommends up to R-49 for attics in most
climate zones. This is equal to approximately 16" of
typical attic insulation. Most older homes have
between 3" and 6" of insulation.
To learn how much insulation a home might need,
simply measure the thickness of the attic’s existing
insulation with a ruler. Take the insulation thickness
and multiply by 3.14 to get the approximate R-Value of
the existing insulation.
Then check the NAIMA chart to see what the DOE
recommends for the area where the home is located.
How to determine how much insulation
a home needs
It’s easy to calculate the number of insulation packages
needed to complete a project:
ultiply the length by the width to determine total
M
square footage to be insulated.

Measure the distance between joists or studs
to determine correct insulation width for the job
(16" or 24").

hoose the appropriate insulation product (R-Value,
C
thickness and width) for the home insulation project.

Choose the insulation product width to match distance
between joists or studs – 16" or 24". If the joist cavity
is full, insulation width makes no difference because
you should install new insulation across
the top of the joists.

Divide
total square footage to be insulated by
square footage per package. Round up to the next
whole number to determine total number of
packages required.

Site preparation and PPE
Site preparation and personal protective
equipment (PPE)
Insulating is a safe DIY project when the insulation is installed
properly. Refer to the following tool checklist and tips before
beginning insulation projects.
Gather the proper equipment, tools and
protective clothing
Special equipment
 Portable work light
 Boards or sheets of plywood (provide a safe place
to sit or kneel in an unfinished attic and a surface
on which to cut the insulation)
 Insulation supports (for holding the insulation
up under floors)
Basic tools
 Tape measure
 Utility knife or insulation saw – a knife with a serrated
blade is best.
 Straightedge or 2 x 4 (for cutting insulation)
 L ightweight, squeeze-type stapler
(optional - to install vapor retarder)
 S crew gun (drill) and appropriate fasteners
(when applying interior finish over insulation)
Protective gear
 Work gloves, loose-fitting, long-sleeved shirt,
long pants and cap
 O SHA-approved safety glasses for overhead work
 Disposable dust respirator is recommended, but
not required (NIOSH-certified – N95 or greater)

11. Avoid unnecessary handling of scrap materials by placing
them in waste disposal containers before removing them
from the site.
Air sealing
Proper air sealing should be completed prior to ROXUL
COMFORTBOARD®, ROXUL COMFORTBATT®,
OR ROXUL ROCKFILL™ insulation to ensure full performance
of the insulation. Verify all holes and seams between sheet
goods such as drywall, sheathing, and subflooring at the
building envelope are sealed with the durable caulk, tape,
and/or foam seals.

Safe Occupancy
There are no re-entry / re-occupancy requirements for this
project. You may re-enter the premises immediately following
installation.
Tips for controlling and reducing dust
Safety
Another important safety consideration when handling
insulation is dust control. These recommended work
practices help to minimize itching of the skin.
Section 410-66, of the 1978 National electrical Code states:
Recessed portions of enclosures, other than points of
support, shall be spaced at least ½ inch from combustible
materials. Thermal insulation shall not be installed within
3 inches of the recessed fixture enclosure, wiring
compartment or ballasts and shall not be installed above
the fixtures as to entrap heat and prevent free circulation
of air unless fixture is otherwise approved for that purpose.

A simple way to increase attic insulation R-Value
and lower energy costs for homeowners is to
top up their existing attic insulation.
Attic
If you want to increase home comfort and save energy year 'round, start by reducing the heat loss through the attic,
|the most cost-effective place to add insulation. If the current insulation has settled and isn’t flush with the top of the
joists, add an extra layer of ROXUL COMFORTBATT thermal batt insulation to bring it up to the top of the joist.
ROXUL COMFORTBATT can be be used in a vented or unvented attic, if the attic is vented ensure air flow is not
restricted by installing baffles on the underside of the roof at the eaves/soffit prior to insulating.

Top Up the Attic Insulation In Just 3 Easy Steps
A simple way to increase insulation R-Value and lower
energy costs is to top up the existing attic insulation.
While the attic is probably insulated, over time, that
insulation can settle or compact, reducing its R-Value.
Or if the attic is breezy, insulation can drift and shift,
leaving gaps where heat can escape. When installed,
ROXUL ROCKFILL™ Insulation won’t move or settle over
time. And, ROCKFILL™ is made of inorganic materials
and thus will not grow mold.

2. Aerate
Cut open and remove from bag.
Installing ROCKFILL is easy to apply over existing
insulation by hand, and there is no blowing machine
required. To achieve an R49 rating, top up your attic
insulation to a depth of 17.3 inches. Seal all holes
and penetrations with caulking before installing
ROXUL ROCKFILL. See ROXUL ROCKFILL Coverage
Chart in the appendix for recommended installed depth
needed to achieve various R-Values.

ROCKFILL adds R12 of insulation.
Areas around pipe, wiring and attic vents are
often neglected and can account for the majority
of those gaps and voids. ROXUL ROCKFILL
loose-fill, top up attic insulation makes it easy
because unlike other attic insulation, there is no

Crawlspace
Many home and cottage owners can enjoy additional
benefits by insulating their crawl spaces. In some
cases, the most difficult aspect of insulating a crawl
space is having enough room to work around to
properly install the insulation. If the crawl space area
is easy to get at, the installation of ROXUL insulation
is quite simple.
Typically, there are two types of crawl spaces – they
are defined by either being vented or non-vented.
The difference in how the two crawl space types are
insulated is defined by either applying insulation to the
exterior wall, or to the ceiling/floor between the heated
living space and the crawl space.
ROXUL Insulation: a two-tiered solution
to insulating crawl spaces
COMFORTBOARD™ IS and the effects of
thermal bridging
ROXUL has two thermal insulation products
for interior crawl space wall assemblies:
ROXUL COMFORTBOARD™ IS (Insulation Sheathing)
and ROXUL COMFORTBATT®. When used in tandem
within the 2 x 4 stud wall cavity, these two products help
create a drier, more comfortable space.
Before recommending the Good, Better, Best
R-Values for the crawl space wall assembly, we need
to understand thermal bridging – the process that
describes a material’s capacity to conduct heat
from one material to another.
®
®
A vented crawl space can be notorious for dampness,
but ROXUL insulation is water-repellent, moistureresistant yet vapor-permeable. The permeance of
ROXUL products allows moisture vapor to pass through
the insulation without being trapped. In the unfortunate
event of basement leak where the insulation becomes
wet, ROXUL insulation quickly dries out and maintains
its R-Value. Unlike other insulations, ROXUL won’t
absorb water and is not susceptible to mold.
In a typical crawl space, cold air transfers from the
outside concrete foundation through the wood studs
and eventually into the living space. The studs perform
as the conduit or “thermal bridge”, lowering the
R-Value of the wall assembly. Insulated sheathing like
COMFORTBOARD™ IS reduces this thermal bridging,
blunting the effect of thermal bridging between the
concrete and the studs.
17
®
Vented crawl space installation
Vented simply refers to the space having air vents,
typically more than one, and they are generally located
across from one another at the upper part of the
foundation wall. The vents allow for an air exchange,
helping to eliminate dry rot, moisture build-up, and
other conditions that can develop in these enclosed
spaces. This type of venting would be very common
in a lot of older homes.
1
A vented crawl space is treated in the same manner as
a cantilever, or insulating a room where the underside
is exposed. The underside of the floor is insulated by
adding batt insulation between the floor joists.
Step 1
Seal all joints and penetrations with caulk and where required by local building
codes, install a vapor retarder to the underside of the sub-floor before insulating.
2
Step 2
Insert, Compress and Release to install ROXUL COMFORTBATT® thermal insulation
between the floor joists.
3
Step 3
Permanently hold the insulation in place by installing strapping on the underside
of the floor joists perpendicular to the insulation. Attach minimum 2 pieces of
strapping using appropriate screw, nails or staples. Some options for strapping
include wood, plastic, wire and chicken wire mesh. At least one piece ofstrapping
should be installed for every 8 inches of insulation.
4
Step 4
Seal all joints and penetrations with caulk and where required by local building
codes, install a vapor retarder to the underside of the sub-floor before insulating.

Non-Vented crawl space installation
A non-vented crawl space is defined as having a heating
or cooling source, or some other source that conditions
the air within the crawl space. Conditioning the room
helps to minimize moisture build-up in the space, and
helps to avoid the growth of mold.
A non-vented crawl space is insulated in the same
manner as a conditioned basement. The exterior
foundation is framed in with studs, and the insulation
is then installed between the studs.

Dirt floors of a non-vented crawl space should be
covered with a suitable vapor barrier before insulating.
All joints of the vapor retarder shall overlap by 6 inches
(153 mm) and be sealed or taped. The edges of the vapor
retarder shall extend at least 6 inches (153 mm) up the

Thermal insulation systems for
residential exterior wall applications
As society demands more energy-efficient houses,
building codes and builders (and DIY homeowners)
are responding by increasing the R-Value of the building
enclosure, in particular, the above grade exterior wall.
Given that the cavity of the standard
2 x 6 wood frame wall used in residential housing
(new construction) is already filled with insulation,
the clear path forward to higher R-Values is to
add layers of exterior insulation.
ROXUL COMFORTBOARD™ IS is a rigid stone wool
insulation board fastened to the outside face of the
exterior studs used in residential construction and
designed to provide increased thermal performance
to the building envelope.
What makes ROXUL COMFORTBOARD™ IS
a superior exterior insulation sheathing
Greater drying potential than foam llastics
COMFORTBOARD™ IS is a moisture-resistant, yet
vapor-permeable insulation (30-40 perms) and
will allow transient vapors to pass through without
restriction. This unique vapor-permeable quality of
ROXUL's cavity wall insulation allows for an increased
potential for drying without trapping moisture
in the wall assembly.
Lower permeable insulations, such as foam plastics,
can act as vapor retarders and negatively affect the
drying potential of many typical residential
wall assemblies.
Fast outward drying
Highly permeable insulation like COMFORTBOARD™ IS
has the added benefit of allowing fast outward drying
during cold weather. This dries the wood frame cavity
very quickly, even if the framing is wet from construction
or becomes wet because of incidental water leaks.
How to insulate a typical above-grade
exterior wall
Exterior walls should be insulated to their maximum
R-Value. If the walls are constructed with 2 x 6 studs,
then COMFORTBATT® R-23 batts should be used.
R-23 batts are 5 ½ inch thick and snugly fit into
a 2 x 6 cavity wall.
When installing COMFORTBATT between the wall studs,
eliminate any gaps and ensure the ends butt snugly
together. Ensure the surface of each batt is
flush with the interior surface of the studs.
If the home is older and built with 2 x 4 studs
for the exterior walls, never attempt to squeeze
COMFORTBATT R-23 into the wall cavity.
Compressing the insulation will cause it to
lose its effective R-Value – instead install
ROXUL COMFORTBATT R-15.
Another option to improve the wall’s thermal
performance is to build out the studs by adding
2 x 2 strapping/furring to the existing edges
of the 2 x 4 studs, which will create a 2 x 6
stud wall. COMFORTBATT R-23 can then be
added to the expanded deeper cavity and end up
with increased insulation R-Value.
Vapor retarders in cold climates
Typically, a vapor retarder is installed on the warm
side of the wall, over the insulation and studs. Use the
least amount of staples that will hold the vapor retarder
up, seal all vapor retarder seams with suitable tape
to completely seal the wall. This reduces the chance
of warm air getting into the wall cavity, where it can
contribute to condensation and cause mold problems.
25
*Check the local building code for approved vapor barrier/retarder information.

Frequently asked questions
What is R-Value?
R-Value is the measurement of the insulation's ability
to prevent heat flow. The higher the R-Value, the more
insulating power it provides. Batt insulation works by
restricting the air movement in the insulation.
What is the difference between stated R-Value and
effective R-Value?
If a vapor barrier is installed in an attic, is ventilation still required?
Yes. Even with a good vapor retarder, proper
ventilation is considered essential to prevent damage
from condensation. Soffit vents – openings at the roof
overhang – combined with a ridge vent, roof vent or
gable vents are effective ways to create a positive
movement of air in and out of the attic.
Stated R-Value tests measure only thermal resistance.
It does not take into account factors such as thermal
bridging across the building envelope.
If the vapor retarder is accidentally torn, is repair necessary?
While the stated or nominal R-Value of an insulation
product is important, accounting for the thermal
bridging will influence the effective R-Value
of the wall system.
Not usually. The edges should lie close enough together
to block most of the water vapor. To fix a large tear,
seal the two edges together with a proper contractors
sheathing tape. It is important to fix if the vapor retarder
is also acting as part of the Air Barrier System.
What is a vapor retarder?
A vapor barrier or retarder controls vapor transmission
and helps prevent condensation and excessive relative
humidity levels within the walls, floors and ceilings of
the home. Vapor barriers/retarders are particularly
important in Canada, and in states in the U.S. that
experience winter temperatures below freezing.
The three most common types of vapor retarders –
kraft paper, foil-backed paper and polyethylene
(a separate 4- to 6-mil polyethylene film applied
over installed insulation). There are a few other less
common vapor retarder products such as smart vapor
barrier or latex paint combined with gypsum board.
Do higher insulation levels create condensation
problems?
Yes, potentially, but not if the building envelope is
designed properly.
Insulation helps keep heat in during the winter
months, but what is the benefit to having it during
summer months?
Insulation helps slow the process of summer heat
entering the home, which helps keep the inside cool and
reduces the need for continuous air conditioning.
How does one add layers of attic insulation to a joist
cavity that is only half full?
If a joist cavity is only half full and the recommended
insulation level in the home's area is R-38, fill the joist
cavity flush with the top with the appropriate thickness
of unfaced ROXUL COMFORTBATT® insulation. Then lay
a second layer of unfaced insulation perpendicular to
the existing layer to give a total of 12” (or an R-Value of
38) in the joist cavity. Covering the attic joists with the
second layer will reduce heat loss through the wood.
27
®
What is ROXUL insulation made of?
®
ROXUL insulation is a rock-based mineral fiber
insulation comprised of basalt rock and recycled slag.
Basalt is a volcanic rock, which is abundant in the
earth, and slag is a by-product of the steel and copper
industry. The minerals are melted and spun into fibers.
The end product is called “stone wool.”
®
Is ROXUL insulation safe?
Yes. A study showed that there were no increases in
risk of cancer for users or workers for the production
of rock wool. The International Agency for Research on
Cancer (IARC) has updated the previous Monograph and
classification of 1987, concerning the health effects of
various MMMF (Man-Made Mineral Fibers), excluding
them from Group 2B (possibly carcinogenic).
In addition, ROXUL insulation is fire-resistant.
It can withstand temperatures up to 2150 ºF
(1177 ºC). Consequently, it does not contribute either
to the development and spread of fire or the release
of toxic gases.
It is water repellent, which means that the insulation
cannot absorb water. Plus it resists rot, mildew, mold
and bacterial growth, contributing to a safer indoor
environment.
What happens if ROXUL insulation gets wet?
ROXUL insulation is moisture-resistant yet vaporpermeable. In the event the insulation becomes damp or
wet, the insulation, when thoroughly dried, will maintain
the original performance characteristics.
Is ROXUL insulation mold-resistant?
ROXUL products are inorganic, providing no food
source for mold to grow. ROXUL products are tested
to ASTM C1338 – Standard Test for Determining Fungi
Resistance – and pass with zero fungal growth.
Does ROXUL make blowing wool insulation?
ROXUL insulation is only manufactured in batt, board,
loose wool and pipe forms.
Is there any "off-gassing" from ROXUL products?
No, “off-gassing” is a term that was started when
blowing agents were utilized in insulation materials
and ROXUL does not incorporate blowing agents
in our products.
28
Can ROXUL insulation go around the pipe of a gas
fireplace where the pipe meets the exterior wall?
Although ROXUL stone wool insulation is a noncombustible material, which has a melting point of
2150 ºF, ROXUL does not have any approvals for this
application. We recommend contacting the manufacturer
and/or follow local codes for this application.
What is the fire rating of a ROXUL product?
A fire rating is determined by testing a complete
system, such as a wall with all its components,
and not the insulation alone. ROXUL products are
non-combustible and have an approximate melting
temperature of 2150 ºF, but cannot hold a fire rating
by itself, as is the case with any other insulation.
Contact ROXUL Technical Services at 1-800-265-6878
for a specific fire rating.
What is the difference between ROXUL
COMFORTBATT® and ROXUL SAFE‘N’SOUND®?
ROXUL Inc produces stone wool insulation products
designed and optimized for specific applications.
ROXUL SAFE’N’SOUND acoustical fire batt insulation
is designed, tested and optimized for acoustical
performance in interior wall assemblies; it is not
intended or routinely tested for exterior wall thermal
application where R-value is of interest.
ROXUL COMFORTBATT® thermal batt insulation is
designed, tested and optimized for thermal (R-Value)
performance in exterior wall assemblies; it is not
intended or routinely tested for interior acoustic
application where decibel reduction is of interest.
It is always best to use the correct ROXUL® stone
wool insulation product, optimized for a particular
application – i.e. use ROXUL® SAFE’N’SOUND for
interior acoustic and fire applications and use ROXUL®
COMFORTBATT® for exterior wall thermal applications.
Is a vapor retarder required on all applications using
mineral wool insulation?
A vapor retarder is only required when the application
involves an exterior wall. A vapor retarder is meant to
restrict water vapor transfer from the warm side and
condense on the cold side of the wall. A vapor retarder
is always attached to the warm side.

Will ROXUL insulation products pass building code
inspections?
How much clearance is needed when insulating
around pot/recessed lights?
Yes, the insulation will pass building code inspections
as ROXUL tests to CAN/ULC S-702 Standard For
Mineral Fiber Thermal Insulation For Buildings,
and ASTM C665 Standard Specification for Mineral
Fiber Blanket Thermal Insulation for Light Frame
Construction and Manufactured Housing as required
by the NBCC (National Building Code of Canada), the
ICC (International Code Council) and IBC (International
Building Code). In addition, there are CCMC numbers
on the COMFORTBATT® products. As a result, ROXUL
insulation has met all the criteria needed for Canadian
and United States residential codes.
Insulating around pot lights can vary by manufacturer,
as well as the type of pot light and it may be covered
under local building codes. ROXUL has no set
requirements for insulating around pot lights and
would always recommend following the manufacturers'
recommendations and/or local building codes.
®
®
Can COMFORTBATT be used in my attic?
®
Yes, COMFORTBATT® is designed for exterior walls
and attics. Code requirements for attic R-Value
will vary from province to province, although R-40
is quite common. To achieve R-40 in the attic using
COMFORTBATT®, it is recommended to use two layers
of R-23 for a total of R-46. Lay the first batt between the
roof trusses, then the second layer perpendicular
to the first so as to cover up the roof trusses.
What is the Specific Heat for ROXUL products?
The heat capacity of ROXUL products at 50 ºC is
0.8kJ/kg K (0.191 BTU/lb ºF).
Will ROXUL insulation corrode metals?
No. ROXUL products have been tested and conform to
the stainless steel stress corrosion specification as per
the ASTM test methods C871 and C692.

Fastener guidelines
Design Basis
1. Mechanical attachment
For permanent attachment, ROXUL stone wool
(mineral wool) insulation should be mechanically
attached or pressure held by supporting members.
®
2. Adhesives
Adhesives and adhesive applied stick-pins should
NOT be used for permanent attachment of ROXUL
stone wool insulation. Adhesives, and adhesive based
systems can used for temporary attachment, but
mechanical attachment (or supporting members)
must be used for permanent attachment.
3. E xposed insulation
ROXUL stone wool insulation is not intended to
be left exposed to the elements. Protective layer
should be installed immediately after insulation
attachment. If the insulation is to be left exposed,
or installation takes place in bad weather, ROXUL
recommends a minimum of 5 mechanically attached
insulation fasteners per standard board. Designers
can increase number of fasteners to meet specific
conditions and design requirements (including
wind-driven rain-loads).
6. Wind load (Live Load)
Fastening connections should be designed to
withstand horizontal loads imposed by wind
pressures. Wind loads often govern lateral
load scenarios.
7. Fastener selection
Fasteners should be:
a) appropriate type for the substrate;
b) capable of withstanding applied pull-out
and shear-loads;
c) numerous enough and of large enough
cross-section to prevent tear-through of the
insulation under expected conditions;
d) s uitable for use outside if being used in
exterior applications.
8. Engineered design
The design of fastened connections is a task normally
completed, or reviewed, by a structural engineer.
The primary purpose of this fastener guide is to
provide suggestions for attachment design of
ROXUL stone wool insulation attachment to
various structures and buildings.
4. Design loads
withstand all the combined applied loads, including
(but not limited to) Dead-Load and Wind-Loads.
Where applicable, consideration should also be given
to Seismic- Load, Live-Load and Wind-Driven
Rain-Load (Not covered in this guide).
9. Limitation
ROXUL stone wool insulation boards are suitable for
mechanical attachment using a number of fasteners
and fastening systems. Mechanically attached
fastening systems are subject to various loads
including dead load, wind load and seismic load;
all of which vary with location and over time.
5. Dead load
withstand all the combined applied dead loads,
including (but not limited to) the insulation, fasteners
and any other supported members or cladding.
Warning: Failure to include safety factors or adequately design for
applied loads can result in failure of mechanical attachment. The
determination of the specific design requirements and safety factors
regarding a fastener system is the sole responsibility of the installer
and/or end user. ROXUL Inc assumes no responsibility whatsoever
for any failure of insulation attachment or related fastening systems.

®
Strapping
1. General
Strapping, attached to the building structure, will act
like giant clamps to hold insulation in place. ROXUL
insulation boards will be permanently mechanically
supported by the strapping attachment if the
attachment is designed to withstand live loads and
total applied dead loads. Insulation boards can be
temporarily held in place prior to strapping unless
the insulation is to be left exposed without strapping
or installation takes place in bad weather; in which
case guidelines for Plain Insulation attachment in the
previous section should be followed.

Masonry ties
1. General
Wedges / clips installed over masonry ties can
be used to attach ROXUL insulation boards.
Non-proprietary or proprietary masonry ties
can be used.
®
2. Design
Spacing and design of the masonry tie pattern
should follow accepted practice and be adequate to
support wind and dead loads. Where permissible
by codes and design, the spacing of ties should be
made to be 16” or 24” in at least one orientation
(vertical or horizontal) to allow easy installation
of ROXUL insulation boards with little or no cutting
of the insulation.
3. Insulation Attachment
Wedges or clips over masonry ties can be used to
hold the insulation in place at board edges. Additional
fasteners can be used in the middle of boards if
needed. The average number of masonry tie wedges
and / or fasteners holding a single piece of insulation
should be a minimum of 5. Designers can increase
the number of fasteners or wedges to meet specific
conditions and design requirements.
4. Fasteners
ROXUL recommends wedges or clips designed
for the particular type of masonry tie being used.
If additional fasteners are required in the middle
of boards these can be:
Plastic cap nails
 Screws & washers
 Insulation fasteners
 Impaling pins

5. STPE – Adhesive WRB
Some STPE based WRB (Weather Resistive Barrier)
compounds have adhesive properties prior to
curing and can be used to attach ROXUL stone wool
insulation to the wall when used in combination with
brick ties and wedges around board edges. Follow
manufacturers direction when using an STPE based
WRB as an adhesive for ROXUL insulation.

®
Clips & girts
1. General
Proprietary clips/brackets or nonproprietary
stand-offs designed to support vertically installed
z-girts or L-channels can be used. Insulation is not
required to provide any structural support with this
type of system.
2. Thermal bridging & z-girts
ROXUL does NOT recommend using z-girts
through the full thickness of insulation. Clips,
brackets or stand-offs should be used to
minimize thermal bridging.
3. Design
Z-girts and fastening system should be designed
to support wind loads and total applied dead loads
independently of the insulation. If clips & girts do NOT
provide structural support to the insulation it should
be fastened per directions for Plain Insulation. If clips
& girts provide structural support to the insulation
then designers can reduce the required number of
fasteners appropriately.

01. General
a) D
etail is applicable to light-weight cladding systems
including vinyl siding, wood siding, and fiber cement
siding or panels with ROXUL COMFORTBOARD™
ISthicknesses greater than 1.5” (38 mm). For
heavyweight cladding systems, see ROXUL
CAVITYROCK™ Application Guide. Detail is applicable for
ROXUL COMFORTBOARD IS thicknesses less than 1.5”
(38 mm), with the exception that “perfect barrier” type
cladding can be directly attached to framing through
insulation as per cladding manufacturer’s instructions.
02. Structure
a) A
wood frame is illustrated in this detail. Alternates
for the infill wall structure include light gage metal
stud with exterior gypsum board sheathing and a
CMU structural wall.
03. Rain water control layer
a) A
drained-screen approach to rain water control
(as illustrated) is recommended.
b) The drainage plane material is the primary rain water
control layer in the wall assembly. Water penetrating
the exterior cladding must be directed to the exterior
by this layer.
c) Material options for the drainage plane shown in the
wall assembly above include:
i. non-perforated housewrap or building wrap
ii. building paper
iii. v apor permeable liquid or fluid applied
membrane
iv. vapor permeable “peel and stick” self-adhered
membrane
v. v apor impermeable membranes may be used
depending on vapor control design (see section
06 below).
04. Air control layer
a) T
he drainage plane may be detailed as the primary
air control layer if made continuous.
b) If an air permeable cavity insulation is selected
an airtight drywall approach should be used.
An airtight drywall approach requires all
penetrations of the gypsum board to be carefully
sealed. c. Multiple planes of airtightness are
recommended where practical to control
convection within the enclosure cavity.
05. Thermal control layer
a) R
OXUL COMFORTBOARD IS insulation is the
primary thermal control layer. b. The amount of
insulation recommended varies by climate region
(see ROXUL COMFORTBOARD™ IS application guide)
06. Vapor control layer
a) T
he assembly as illustrated is a “vapor open”
assembly, meaning that there is a single line of vapor
control and that drying can occur towards the interior
or towards the exterior from this line. Selection of
vaporopen interior finishes should be considered. If
vapor impermeable finishes are used, analysis should
be conducted to assess drying potential.
07. Exterior cladding
a) A
drained and back-ventilated wood or fiber cement
siding is illustrated.
b) Increasing the air-gap reduces the amount of solar
driven inward vapor drive
c) Material options for the exterior cladding include:
i. V inyl siding (see manufacturer’s notes for
installation on furring)
ii. Wood siding
iii. Fiber cement siding or panels
08. Quality control considerations
a) I nspect the lapping of drainage plane pieces to
ensure that pieces are installed in “shingle” fashion.
b) Ensure a tight fit where the exterior insulation
boards are fit together. At mechanical and
structural penetrations, an opening in the ROXUL
COMFORTBOARD IS layer may be cut slightly
undersized to ensure a tight fit.
