Five Great Reasons to Recommend Fullback®
Independent testing facilities—certified by the American Society for Testing and Materials (ASTM)—conclude that the Fullback Thermal Support System excels in these ways:
Saves Energy - An ENERGY STAR® partner
Siding with Fullback inside can reduce energy bills. Installed behind the vinyl siding as an underlayment or adhered directly to the siding through a lamination process, Fullback provides an “R”-value of up to 5.0. As an ENERGY STAR partner, we work with the EPA and U.S. Department of Energy to provide homeowners with quality, fuel-efficient products and educational materials.
-
Durable - Resists Impact
In tests performed by an independent laboratory, panels insulated with Fullback can absorb impacts from 160 PSI to 340 PSI depending on the type of vinyl siding. The Fullback Thermal Support System increases the impact resistance of vinyl siding by more than 500%.
Water Vapor Permeability
Fullback discourages the development of mold and moisture condensation behind the wall. Fullback 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 Fullback 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
Fullback even repels termites with PreventolTM®, a patented additive made with a material that is safe for humans and pets
