Thermar8 Insulated Siding
Five Great Reasons to Invest in Thermar8®
Thermar8 Thermal Support System excels in these ways:
- Saves Energy - Nationwide Window & Siding An ENERGY STAR® partner
Siding with Thermar8® inside can reduce energy bills. Installed behind the siding as an underlayment Thermar8 provides a very high "R"-value. As an ENERGY STAR® partner, Nationwide Window & Siding works with the EPA and U.S. Department of Energy to provide homeowners with quality, fuel-efficient products and educational materials and may qualify for Tax Credits.
- Durable - Resists Impact
In tests performed by an independent laboratory, panels insulated with Thermar8® can absorb impacts from 160 PSI to 340 PSI depending on the type of siding. The Thermar8® Thermal Support System increases the impact resistance of siding by more than 500%.
- Water Vapor Permeability
Thermar8® discourages the development of mold and moisture condensation behind the wall. Thermar8® absorbs little water, and has a permeability rating of 5.0 perms per square inch. Material with a perm rating of more than 1 is not considered a vapor barrier, and therefore does not trap vapor behind the wall.
- Fire Resistant
Extensive tests by independent laboratories confirm excellent performance when exterior walls containing Thermar8® are exposed to a radiant heat source. In addition, the thermal support system completely fills the hollow void that exists behind conventional siding products, eliminating the "chimney effect" that can contribute to flammability.
- Repels Pests
Thermar8® even repels termites with Preventol®, a patented additive made with a material that is safe for humans and pets.
