Low-E Reflective Underlayment
What is it?
Therma-Sheet is an energy saving alternative to traditional underlayment. It provides excellent thermal and moisture protection under metal roofing, stone coated steel, clay tile and composite shingles. Therma-Sheet provides an excellent thermal break that can lower temperatures 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..
Why do I need it?
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.
How much does it cost?
Low-E Therma-Sheet runs about 18%-25% of the total roof cost.
