CLASS A FIRE-RATED PROTECTION WITH R-8.24 PERFORMANCE: BEEST FullStop spray foam insulation is Class A fire-rated & meets ASTM E84 fire safety standards for safer, more confident applications. Delivers strong thermal resistance & acoustic insulation with an R-Value of 8.24 at 2” thickness
ALL-IN-ONE SPRAY INSULATION FOAM KIT FOR ~480 BOARD FT COVERAGE: Our FullStop kit covers up to 480 board ft. with an all-in-one expanding foam, helping you skip a costly contractor. Helps reduce outside noise & build a calmer, more comfortable space. Ideal for basements, roofs, sheds, garages & more.
ADVANCED HYBRID FORMULATION WITH CLOSED-CELL STRENGTH & OPEN-CELL EXPANSION: Unlike standard foam options, the BEEST spray foam insulation kit combines a closed-cell outer skin for strength, moisture resistance & high R-value with an open-cell core for superior expansion, flexibility & coverage.
LOWER ENERGY BILLS WITH A STRONGER AIRTIGHT SEAL: Our open and closed cell spray foam expands consistently within the recommended 68-77°F application range to fill gaps & cracks. High thermal resistance improves year-round comfort by keeping heat out in summer & locking warmth in during winter.
STRONG ADHESION ON WOOD, METAL, DRYWALL, CONCRETE & MORE: BEEST spray foam kit uses an ozone-safe, moisture-cured polymer that securely bonds to multiple surfaces, including drywall, brick, wood & metal. A recommended 2” layer blocks air leaks, moisture entry & condensation buildup
AMERICAN FAMILY-OWNED WITH USA SUPPORT: BEEST FullStop spray foam insulation is proudly owned by a U.S. family. Our U.S.-based customer care team is available 24/7 and ready to help whenever you need technical support, product guidance, or assistance.
