FROTH-PAK™ Foam Insulation and Sealant

FROTH-PAK™ Polyurethane Spray Foam is a two-component professional insulation and sealant kit. FROTH-PAK comes as a professional sealant for air sealing gaps and penetrations up to 4 inches wide or as a spray foam insulation to fill larger cavities providing both insulation and air sealing properties. The newest member of the FROTH-PAK family is FROTH-PAK ULTRA, a low-pressure spray foam that performs in many ways like a high-pressure spray foam. FROTH-PAK kits comprise two pressurized tanks, linked by hoses, to a dispensing gun. When the contents of the two tanks are dispensed, they chemically react to produce a froth-like substance, which quickly expands to about three to five times the dispensed volume. The foam solidifies in about 60 seconds and fully cures into a solid permanent structure in approximately five minutes. Cured foam resists moisture, insulates, dampens noise, adds structural support, provides an air-seal and fills voids.
