Firestop Supplies at Capitol Materials

For construction customers across AL, FL, GA, LA, and MS

In construction, firestop is an integral part of a complete fire protection strategy. Openings around pipes, exhaust systems, conduits, and ductwork create voids through which smoke, flames, and/or gas can spread. Firestop materials are used to fill those openings in passive fire protection systems, seriously inhibiting spread and protecting property and lives in the process.

Firestop products come in multiple forms (silicones, mineral fiber, mortars, rubber, etc.). Regardless of type, firestop supplies should be vetted and approved by Underwriters Laboratories® or a similar reputable organization for adherence to updated regulatory and safety standards.

For builders in Alabama, Florida, Georgia, Louisiana, and Mississippi and construction professionals worldwide, having the right firestop products on hand helps make jobs faster, safer, and more efficient. Capitol Materials is here to help.
