This two-part, latex-based foam seals cracks and penetrations through a building envelope, and from floor to floor. Approved for use as a fireblock, and around plumbing penetrations and electrical wireways, it’s the only self-forming gasket system offering energy code compliance. By keeping airborne moisture from entering wall cavities, EnergyComplete also reduces the chance of mold growth, and creates a first line of defense against insects and other pests. This sealant is non-allergenic, and safe to use without a chemical mask or ventilation suit.

This open-cell, semi-rigid, polyurethane foam does away with ozone-depleting propellants by being completely water blown. With a density of 0.5 per cubic foot and a minimum of 3 percent bio-based material, this product expands 100:1 when sprayed, filling voids and crevices and reducing infiltration—and consequently, energy demand. With an R-value of 3.8 per inch—R-20 at 5.5”—Bio-Based 501W contributes to a tight building envelope, while reducing the risk of moisture accumulation and sound transfer.
