HandiFoam® low-pressure spray polyurethane foams (SPF) and low-pressure pour-in-place polyurethane foams (PIP) are chemically cured and designed for the professional to fill large voids and surfaces. Compared to standard insulation products, HandiFoam® products offer higher insulation values, are easy to install, and provide complete air tight coverage when properly installed. Stopping unwanted air infiltration is one of the most important and cost-effective ways to reduce heating and cooling costs, improve indoor air quality, and provide a more durable, energy-efficient structure.
