ASF 0.5-B is a high-performance, two-part, water-blown polyurethane foam insulation system designed for superior air sealing and thermal performance. When sprayed in place by trained professionals, it rapidly expands to fill gaps, cracks, and voids, creating a fully adhered, monolithic insulation layer.

With its 0.5 pcf light-density composition, ASF 0.5-B provides excellent control of air infiltration while delivering a high R-value per inch. It serves as an effective barrier against noise, dust, and pollen, contributing to improved indoor air quality and enhanced comfort. Unlike traditional insulation materials such as fiberglass or cellulose, ASF 0.5-B will not settle, shrink, or degrade over time, ensuring long-lasting performance for residential, commercial, and industrial applications.
