99112831 Fire Block Insulating Foam Sealant, Orange, 12-oz.

Great Stuff Fire Block Insulating Foam Sealant is a ready-to-use, minimal-expansion insulating foam designed to fill and seal gaps up to 3/4 inch while restricting airflow. This distinctive orange foam seals electrical wiring run through wall studs and other service penetrations in walls and between floors to help maintain a fire block barrier. It provides a simple, cost-effective way to maintain the continuity of an approved fire block material throughout the house.

Fire blocking is critical to slowing the spread of flames and smoke through building cavities. The bright orange color makes it easy to visually identify sealed penetrations for code compliance inspections, ensuring that fire blocking requirements are met throughout the structure.
