Bissett Low Expansion Insulating Foam, Straw Can

Doors, Windows & Gaps | All-Season Use

The Bissett Low Expansion Insulation Foam is a professional-grade polyurethane foam designed for controlled sealing and insulating around doors, windows, and gaps where precision is critical. Its low-expansion formula helps prevent frame distortion while delivering a reliable air and moisture seal.

Ideal for both new construction and renovation work, this foam adheres strongly to common building materials including wood, concrete, brick, and masonry. It improves energy efficiency by reducing drafts and air leakage, making it well suited for residential and light commercial applications.

Engineered for all-season performance, the foam applies cleanly in temperatures from -20°C to +35°C. It becomes tack-free in approximately 15 minutes and can be cut after 40 minutes, allowing for efficient workflow on the jobsite. The straw-applied design makes it a practical choice for smaller jobs and touch-ups.

The Bissett Low Expansion Insulation Foam delivers clean, controlled performance for precise sealing tasks, an essential solution for professionals who need accuracy without excess expansion.
