Everkem Firestop-814+ Intumescent Firestopping Sealant

Firestop-814+ is a flexible, red firestopping sealant designed to seal gaps around pipes, cables, and ducts in walls and floors. It expands when exposed to heat, creating a protective barrier that stops fire and smoke from spreading through building penetrations. This sealant works with electrical, plumbing, and HVAC systems in multi-family and commercial buildings. It's tested and certified to meet fire safety standards (ASTM-E814 and ASTM-E1966) for up to 4-hour fire-rated assemblies. It's also compatible with common pipe materials including CPVC, PVC, PEX, and ABS. Firestop-814+ handles freeze-thaw cycles well, applies smoothly, and meets low-emission standards for LEED v4 projects. The bright red color makes it easy to identify during installation and inspection.
