ASF 1.7-B is a 1.7 lb/ft³ density, closed-cell polyurethane foam insulation designed for superior yield, high R-value, and dimensional stability. This advanced spray foam is applied as a liquid and expands in place to create a fully adhered, seamless insulation barrier that significantly reduces air leakage, enhances structural integrity, and provides exceptional thermal performance.

The closed-cell structure of ASF 1.7-B acts as an air and moisture barrier, eliminating the need for additional vapor retarders. By controlling moisture vapor movement, it helps prevent condensation, reducing the risk of mold growth and improving indoor air quality. Additionally, it serves as an effective sound barrier, blocking outside noise for a quieter and more comfortable environment.
