LP TechShield Radiant Barrier Sheathing
One of our favorite energy efficient features that we use when building our homes is something called the TechShield Radiant Barrier. Installed in over one million homes, OSB TechShield Radiant Barrier is the #1 selling brand.

The innovative barrier sheathing prevents radiant heat in the roof from entering the attic, keeping the attic cooler, lowering energy costs, and making the home more comfortable. TechShield is the only radiant barrier sheathing that features VaporVent technology, which allows panels to dry quickly if exposed to moisture during the construction process.

Using TechShield in the construction of your new home can reduce monthly air conditioning costs up to 17%. How amazing is that? It keeps your attic 15-20% cooler, which benefits the heating and cooling equipment found in most attics.

If you're thinking about building a new home, consider using TechShield. For more info on TechShield, check out the video below!
