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. Micro-E Insulation acts as not only an underlayment that will not absorb moisture but also as an insulator. Installed correctly it will seal around fasteners, provide a complete vapor barrier, and stop radiant heat gain/loss. While most underlayments will deteriorate over time Micro-E 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. Therma Sheet reflects up to 97% of the radiant heat that is normally transferred into the attic by super heated roofing materials. It greatly reduces attic heat gain making this space more usable and the rest of the house cooler.
