Firestops provide an important safety measure to help prevent fire, smoke and toxic fumes from spreading during fires through pathways made for installing cables. The STI firestop sealant and putty tubes available at Discount Low Voltage give you an easy, efficient and effective way to provide firestopping in your installs.
These pre-made fire penetration stoppers are simple and quick to use, and will help you meet fire codes, all while delivering peace of mind. The patented two-step intumescent technology STI uses in its cable sealant makes it expand rapidly when exposed to heat and flame to seal off spaces from smoke and dangerous gases. At the same time, these products are unaffected by moisture or humidity. Many of these sealants may be sanded and painted to match their surroundings.
Common applications for our firestop sealants include metallic and nonmetallic pipes as well as cable, cable trays and bus ducts. Our STI fire caulk comes in convenient tubes for fast application with professional results. Choose from cable sealant tubes in a variety of sizes, ranging from 10.1 ounces to 29 ounces. We also carry Specialized Technology caulk guns designed for 11-ounce tubes.
Our firestop putty requires no tools to install and is non-hardening, making it easy to install or remove. That makes it an ideal choice for cable penetrations requiring occasional retrofitting.
