Low-E™ Therma-Sheet Insulation has always offered the benefits of Low-E™ – an industry-leading thermal and moisture barrier - to the roofing industry. Now, Therma-Sheet has earned certification by the International Code Council Evaluation Service (ICC-ES), meaning Therma-Sheet meets all requirements of a stand-alone roofing underlayment for the building industry. Because Therma-Sheet can now be used as a single underlayment product rather than part of a "sandwich" of products, it offers a more affordable means of energy efficiency to homeowners and reduces installation time and required materials.
Therma-Sheet is a 99% pure polished aluminum facing heat laminated to a closed cell foam core. It provides excellent thermal and moisture protection under metal roofing, stone coated steel, clay tile and composite shingles. With an airspace beneath metal roofing, Therma-Sheet reflects 97% of radiant heat. Without an airspace beneath composite shingles, Therma-Sheet provides an excellent thermal break that, without reflectivity, still lowers the temperature below your roof deck 8-12 degrees. Therma-Sheet reflects up to 97% of the radiant heat that is normally transferred into the attic by super-heated roofing materials, significantly reducing attic heat gain. Conversely, Therma-Sheet prevents heat loss through the attic during colder months, all of which reduces heating and cooling costs for homeowners.
Green building is not just a trend, but the wave of the future as more and more homeowners and builders demand energy efficient homes and products. Low-E™ Insulation products are designed for maximum energy and cost efficiency. Whether it's under slab, under roof, around duct work or wrapping the entire house, Low-E™ Reflective Insulation saves more money on heating and cooling than regular insulation and housewrap.
