DAP FireBreak Flame-Resistant Foam Sealant – Orange, 12 oz

Overview

DAP FireBreak Spray Foam is a flame-resistant, all-purpose foam sealant designed to exceed industry testing standards and provide fire protection in high-risk areas. Its self-extinguishing formula works by eliminating oxygen flow through service penetrations, critical points where fire can spread rapidly. FireBreak effectively fills and seals gaps in HVAC, plumbing, and electrical penetrations, as well as joints, partitions, stud walls, stair stringers, soffits, and drop ceilings. The bright orange foam color ensures easy identification after application, while the can includes a stop-and-restart adapter and an extra straw for reuse across multiple projects. For best results, apply in temperatures between 60 and 100 degrees Fahrenheit and use for interior and exterior applications.

Key Benefits

• Self-extinguishing by eliminating oxygen flow in service penetrations where fire spreads most quickly.
• Seals gaps and cracks to block drafts and air infiltration around HVAC, plumbing, and electrical openings, as well as joints and through penetrations.
• Dries tack-free in 10 minutes and reaches full cure in 1 hour; paintable and sandable after cure.
• High-visibility orange foam supports easy post-installation inspection; includes a stop-and-restart adapter and an extra straw for reuse.
• Performs well in UL-175, UL94 V-0, and modified ASTM E-814 tests, indicating robust performance under standard evaluations.

Application and Use Cases

Designed for interior and exterior projects, FireBreak seals penetrations in walls, partitions, and ceilings, including gaps around HVAC, plumbing, and electrical openings. It also fills joints and through penetrations in stud walls, stair stringers, soffits, and drop ceilings. For best results, apply within the 60–100 °F range and fill gaps thoroughly to create effective seals. Once cured, the foam can be painted to blend with surrounding surfaces for outdoor or visible installations.
