Note: This item comes standard with a self taped edge that runs down the 64' length of the product
The Barrier product family is an EPS foam under slab insulation and vapor
retarder, designed to insulate radiant heating projects from heat loss
and retard moisture migration through concrete. The core of the product
is made of flexible, recyclable expanded polystyrene that provides the
excellent insulation characteristics that are needed to maximize energy
savings and minimize heat loss. The unique core has vapor retarding
films bonded to both sides as well as a patented self-taping edge and
overlapping flange to make the entire installation seam-free.
High-performance insulation values, cost-saving installation, and
unequaled flexibility makes The Barrier product family the most
effective radiant floor insulation and vapor retarder in todays market.
Features & Benefits:
- Durable / Flexible / Walkable
- 100% Waterproof and Vapor-proof
- Expanded polystyrene for real insulating value
- Fast / Easy Installation - 4' x 64' rolls for significant labor
savings
- Seamless - Patented factory applied tape edge reduces
thermal bridging
- Printed layout guides for tubing layout or trimming
- Sustainable = Recycled EPS content
- Improved 3" overlap flange
- Full product coverage - no need to purchase additional
material for overlap loss.
Product Use:
Like a foam cup protects your hand from the hot beverage it holds, The
Barrier product family protects concrete from heat loss and moisture
damage, especially when used in a radiant heat floor application. Use in
all floor heating or snow melting applications where the heat should be
driven upwards as opposed to wasting the energy to the ground. Great
uses are in hydronic, electric slab heating or snow melting
applications. Where higher density material is desired, BarrierHL and
XBoard at 25 psi provides the increased support and necessary R-values
such as in slab-on-slab retrofits with thinner concrete over-pours. The
entire product lineup is strong, durable, and utilizes long-lasting
proven R-Value performance without the use of reflective foil.
Installation is far easier because you can walk on all of them without
breaking - plus, the patented seam taping system makes installation fast
and efficient.

Architectural & Engineering Specifications:
The Barrier™ product family may be specified in
construction specifications using the following division according to
Master Specification format:
- Division 7 -Thermal Moisture Protection
- Section 07210 -Building Insulation
- Section 07240 -Exterior Insulation and Finished Systems
Performance Characteristics
The Barrier™ product family has been tested to meet
code specifications as they relate to thermal performance as well as
vapor, water, and moisture barrier requirements.
The industry standard Thermal Conductivity and
Resistance test method using ASTM Standard C-518 - "Standard Test Method
for Steady-State Heat Flux Measurements and Thermal Transmission
Properties by Means of the Heat Flow Meter Apparatus" was used for
testing.
Test Method(s)
The industry standard Water Permeability Test
Method (ICBO Sections 4.6.1 & 4.6.2) and Water Vapor Permeability
Test Method (Procedure B of ASTM E96) were used for moisture transfer
testing.
The industry standard Water Permeability Test Method
(ICBO Sections 4.6.1 & 4.6.2) and Water Vapor Permeability Test
Method (Procedure B of ASTM E96) were used for moisture transfer
testing.

Additional Comments by testing facility:
"This product meets or exceeds the ICBO
conditions for acceptance. At the end of 24 hours, there was NO
indication that any water had dripped from the underside of the
specimens. In fact, a 3.5" head of water (rather than the required 2.0"
head for 24 hours) was employed, with the same results after a period of
96 hours".
ALL TESTING HAS BEEN PERFORMED BY A CERTIFIED TESTING LABORATORY: GEOSCIENCE LTD. - Laboratory Testing Division.
Note: These typical property values are
intended as guidelines only, and not as specification limits. R-value
means resistance to heat flow, the higher the R value the higher the
insulating power.
