Everkem Thermal Seal is a professional-grade, low-pressure polyurethane foam that functions as an all-in-one air sealant and fire block. Engineered for window and door applications, it’s perfect for sealing gaps, penetrations, and cavities in crawl spaces and basements where both air sealing and fire safety are priorities.
This 24 oz gun-grade can dispenses with precision, ensuring minimal expansion for controlled fills that won’t distort frames. It blocks air infiltration while providing an orange, code-compliant fire barrier seal around pipes, wires, and utility penetrations.
Features:
Minimal expansion ideal for framing, windows, and doors
Fire-block formula helps slow the spread of flames, smoke, and gases
Gun-applied for precise control and reduced waste
Great for crawl space and basement air sealing projects
Excellent adhesion to most building materials
Orange foam for code visibility and compliance
Tack-free in under 10 minutes; fully cures in 4–6 hours
