We all know how hot attics can get in the summer months, causing HVAC systems to work overtime. Mark Johnson Custom Homes aims to educate both our clients and readers, so we’d like to share with you a Green product that we use in all of our homes called Radiant Barrier Roof Sheathing.
The product name comes from the ability of the foil coating to be a barrier to the transfer of radiant heat. In the middle of summer, the temperature in attics using this product will be approximately 40% cooler than a home using traditional sheathing. The product is made by laminating a thin, durable sheet of aluminum to OSB.
We use LP® TechShield® in our homes because it is the only radiant barrier with VaporVents, incisions that penetrate the foil, glue and OSB substrate. This patented, post-lamination incising process allows LP TechShield panels to dry more quickly from construction moisture than other radiant barrier panels. Without this incising step, moisture could build up and lead to foil delamination.
But how it is Green exactly? Radiant Barrier Roof Sheathing helps reduce energy consumption. It’s ENERGY STAR®-certified and reduces the heat load on in-attic air handling systems, cutting monthly air conditioning bills up to 17%. Several other factors make Radiant Barrier an environmentally friendly building material; for more information on Radiant Barrier Roof Sheathing, click here
Mark Johnson and his team have extensive experience with Green building, including their Green home in Wilmington, NC. The home was not only Energy Star Certified, but also earned a LEED Platinum Rating, the highest attainable certification from the U.S. Green Building Council.
