Closed-cell spray foam is ideal for exterior walls, basements, crawl spaces, and other moisture-prone areas due to its rigid structure and vapor barrier qualities. Open-cell spray foam, on the other hand, works great for interior walls, offering excellent soundproofing and flexibility. Our team will assess your space and recommend the right option for long-lasting performance.
