SANCTUARY DEFENSE is a high-performance all-in-one cellulose insulation with a proven formula for long-lasting protection against 25 common household pests, including ants, cockroaches, termites and darkling beetles, to name a few. This insulation provides lower heating and cooling bills, comfort, quiet and fire protection.

Treated with BORABARRIER EPA-registered pesticide, SANCTUARY DEFENSE is protected from pests that come in contact with it. There are other access points in a home insects can get into that do not have insulation. SANCTUARY DEFENSE is designed to be an additional layer of protection for use along with ongoing home pest prevention. Blown-in, dense-packed or spray-applied, this cellulose is the smartest way to insulate a home’s attics, walls, ceilings and floors.
