Home Fire Protection Fire Caulks & Sealants
Properly filling construction gaps and blank openings in walls and floors with sealant is absolutely essential to
prevent the spread of fire and/or noxious gases. We offer many different varieties of fire caulk and sealing products, designed to adhere to a variety of materials including glass, metal, non-oily wood, plastics and rubber. Silicone and latex caulks, putty, and expanding foam options are all available, and while tubes are the most common dispersal method for small scale operations (often via a caulking gun), we also have a selection of buckets for spray applications.
