DAP Wall & Cavity Foam

The DAP Wall & Cavity Aerosol Spray Foam is a versatile and efficient solution for sealing and insulating hard-to-reach areas in both residential and commercial projects. DAP, a Century Club manufacturer and trusted name in home improvement and construction for more than 150 years, is known for producing high-quality, durable products. The company’s commitment to innovation is evident in this spray foam, which is designed to make insulation easier and more effective for both professionals and DIYers.

The product’s user-friendly design features a straw applicator that makes it simple to apply. The foam quickly expands to fill cracks, crevices, and wall cavities, creating an airtight seal that prevents air and moisture from entering or escaping. This enhances comfort and improves energy efficiency by reducing drafts and helping maintain indoor temperatures. The fast-curing formula allows users to move quickly through projects without long waiting times.

With an R-value of 5 per inch of thickness, DAP’s spray foam provides excellent thermal resistance, lowering heating and cooling costs. Its durability ensures long-lasting performance, resisting wear, moisture, mold, and mildew. Unlike traditional insulation, it hardens into a solid material, preventing deterioration over time.

The spray foam is highly versatile and suitable for wall cavities, around doors and windows, and in crawl spaces. DAP’s commitment to environmental responsibility is reflected in the product’s eco-friendly formulation—free of CFCs and low in VOCs—making it a safer choice for indoor use.
