Great Stuff Fireblock is specially formulated to impede the spread of flames and smoke through service penetrations by helping to slow the spread of these destructive elements during a fire. Designed for residential construction, it provides an easy and effective way to maintain the continuity of an approved fire block material.
Great Stuff Fireblock Insulating Foam Sealant is a minimal expansion polyurethane insulating foam sealant that fills, seals and insulates gaps up to 1/2". Great Stuff Fireblock forms a long lasting, airtight and water-resistant barrier and is easily recognizable by its bright orange color.
In addition to impeding the spread of fire and smoke through service penetrations, Fireblock seals holes, gaps and cracks to help air from leaking out of or seeping into the home. Air sealing and insulating projects around the home can typically save homeowners up to 30% on home energy costs according to the Residential Energy Services Network (RESNET).
