When people think of a roofing underlayment they most likely will picture asphalt felt paper. ESP has revolutionized the roofing industry by introducing the first underlayment that will actually work for the homeowner. Therma-Sheet Insulation acts as not only an underlayment that will not absorb moisture, but also as an insulator. Weighing only 18 lbs., the 500 sq.ft. rolls are very easy to install. Installed correctly it will seal around fasteners, provide a complete vapor barrier and stop radiant heat gain/loss. It can also be left exposed when "drying out" time is needed. No other underlayment can offer this much for the price. Therma-Sheet can be used as part of a cooling roof strategy and meets stringent California codes. Homeowners will be placing a product on their roof that will pay for itself by saving them money on utility bills. While most underlayments will deteriorate over time, Therma Sheet will last the life of your roofing system.

It is a 99% pure polished aluminum facing heat laminated to a closed cell foam core. Preferably it is used in conjunction with traditional felt paper. Therma-Sheet provides excellent thermal and moisture protection under metal roofing, stone coated steel and clay tile. The product is very lightweight and easy to install. The material composition of Therma-Sheet allows it to outlast and outperform yesterday’s underlayments. Therma Sheet reflects up to 97% of the radiant heat that is normally transferred into the attic by super heated roofing materials. Therma-Sheet used under your roofing system will help cut your summer air conditioning bills. It greatly reduces attic heat gain making this space more usable and the rest of the house cooler.
