The Open Cell 2-Component Spray Foam Kit is a professional-grade, DIY-friendly solution designed for superior air sealing and sound damping. This kit uses a low-density, flexible polyurethane foam that expands significantly upon application, filling every nook, cranny, and crevice to create a high-performance thermal and acoustic barrier.

Unlike closed-cell foam, open-cell foam remains flexible after it cures. This allows it to move with your home’s structure while providing an airtight seal that prevents drafts and reduces energy costs.
