Product Overview

A wet crawl space leads to mold, musty smells, and water damage. Water damage lowers your home’s value while mold can threaten your family’s health. However, with the Armorboard Radiant GPS Form Insulation, you can insulate your crawl space against moisture, increase your home’s value, and protect your family.

Our product is infused with graphite. This infusion creates higher R-values than our competitors. Furthermore, Armorboard outperforms traditional rigid foam insulation by up to 20% and gives you better protection. Lastly, Armorboard is easy to install with a nail-gun or plastic fasteners.
