Foam sealants are essential for achieving airtight, weather-resistant, and fire-rated seals in residential and commercial applications. Whether you're tackling minor home repairs or large-scale insulation jobs, SPRAYMAN’s polyurethane-based spray foam sealants deliver excellent coverage, adhesion, and durability. These expanding foam solutions are ideal for closing off gaps, sealing around windows, doors, and pipe penetrations, and improving thermal insulation.

SPRAYMAN’s collection includes a wide range of foam sealants formulated for specific applications—from gap sealer and crack sealer solutions to fire block and rodent-proof formulations. Our polyurethane foam sealant products are easy to apply and designed to resist moisture, mold, and air infiltration. Whether you're sealing a drafty window or fireproofing a basement wall, we offer the right foam for the job.

What Are Foam Sealants?

Foam sealants are expanding materials that fill cavities, joints, and small openings in buildings. Once applied, they harden into a solid barrier that prevents the transfer of air, moisture, noise, and heat. Foam sealants work alongside traditional insulation materials to enhance overall energy efficiency.

SPRAYMAN’s spray foam sealants provide durable, long-term protection. They serve as air seals, help prevent mold and pest intrusion, and maintain indoor comfort by reducing noise and drafts. Depending on your needs, you can choose low- or high-expansion options with features like fireproof insulation, fireblock foam, or waterproof foam sealant performance.
