Crawlspace Depot: Bora-Foam

Bora-Foam is the first termite-resistant expanded polystyrene insulation designed for basements and enclosed crawlspaces. It is an important component in preventing termite infestation and moisture. Bora-Foam is made by a process using a borate-based product (registered by the U.S. Environmental Protection Agency) that is a deterrent to termites.  This product is incorporated into the insulation during the manufacturing process.  Furthermore, Bora-Foam has a vapor permeance ≤0.08 and provides R-11 insulation for up to 20% energy savings, the company says, noting that Bora-Foam is safe for handling and is non-corrosive.
