Fire stop barriers are critical components of fire protection systems that effectively seal gaps and openings to prevent the spread of smoke and fire in residential, commercial, and industrial facilities. Made from robust yet lightweight pillow-like silicone-based compound material, our premium pillow barrier provides a dependable long-lasting seal suitable for installation on round ducts with diameters ranging between 4 inches to 20 inches perfect for protecting air transfer openings in HVAC or chimney systems where other fire-stop methods cannot be utilized.
