The Precision Sealant That Won’t Warp Your Frames.

Stop worrying about bowing or distorting your expensive window and door installations. The Soudal Soudafoam Window & Door Straw Grade Foam is a professional-grade, one-component polyurethane foam specifically engineered for tight-tolerance applications. Unlike high-expansion foams that can crush frames, our formula is designed to expand minimally, providing an airtight, water-resistant seal exactly where you need it.

Whether you are a contractor sealing a perimeter or a homeowner tackling a drafty window, this straw-grade canister delivers a consistent, controllable application. Its moisture-curing technology creates a durable thermal and acoustic barrier that stops drafts, moisture, and noise in their tracks, all while maintaining its shape without shrinking or cracking over time.
