Could an aluminum and polystyrene sandwich help make your home more energy efficient? That is claim made by Billy Ellis Roofing LLC with their popular “green” roof decking product known as ThermaDeck. Their claim has a lot of backing thanks to laboratory testing by Oak Ridge National Laboratory and pages of happy customer testimonials with lower heating and cooling bills. Lets look a little closer at how ThermaDeck works.

Have you ever been in your attic in the middle of the Summer? If so, I am willing to bet that you did not stay long. Temps in the attic on the hottest days can get near 200 degrees. This cooks your shingles and can cost you a fortune as your air conditioner tries to keep-up. Heat travels into your attic through Radiation, Convection, and Conduction. The ThermaDeck has a aluminum skin that reflects the radiant heat. The Polystyrene adds an insulation value to help prevent heat from being built-up. Then convection currents are used to vent the heat AWAY from your attic space. The conventional decking is installed over the ThermaDeck and a cavity allows the air to vent the attic. Great idea!

This product offers a radiant barrier, extra Insulation, and proper ventilation. This design does much more than a typical vented roof because they are not allowing the heat to build-up in the attic. In fact, the hotter the outdoor temps, the greater the flow of hot air evacuated by the ThermaDeck venting process. Bill Ellis has been in the building business since the 1960′s so he is no “Johnny come lately”. He has developed several outstanding products that are featured at his website http://www.billyellisroofing.com. We appreciate Bill’s contribution to improving the Building process. He is truly a man with New Building Ideas. :-D
