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.

New Hanover County, NC Green home builder Mark Johnson Custom Homes’ LEED Platinum rated home was featured on EcoHomeMagazine.com last month. Jennifer Goodman highlighted our first venture into building with Insulated Concrete Forms (ICF’s) and how it led to the highest Green rating for a home by the U.S. Green Building Council. Below is an excerpt from Goodman’s report and to read the complete article, click here!
Nine months later—after a crash course in high-performance building techniques—Johnson not only had produced an innovative home, but an award-winning LEED-H Platinum dwelling constructed with insulated concrete forms (ICFs) that will save $2,200 on utility bills and more than 100,000 gallons of water a year.
‘We weren’t initially planning to build a green home,’ says his brother, Kevin Johnson, director of business development for Mark Johnson Custom Homes. ‘But we knew it needed to be something a bit different, because the market was starting to slide.’
The brothers’ leap into green building began at a concrete symposium in Charlotte, N.C., where they learned of the environmental and storm-resistant benefits of concrete-built homes. They felt that building with ICFs, which boast a wind rating of up to 250 mph, would be just the thing to get buyers in their coastal city to take notice.”
