Caulks and Sealants

Caulks and Sealants

Here you will find Fire Rated Caulks to help you seal joints, gaps and seams for your firestop devices. These caulking products are great for helping you achieve airtight, watertight and fireproof environments in both marine and building applications.

Fire rated sealants are most often used in assembles and joints to prevent the penetration of fire, smoke, dust, noise, gas and water through your firestop barriers.

The three basic functions of a sealant are to firstly fill gaps between substrates, secondly the sealant itself form a barrier via adhesion to the substrate and as a result of its own firestopping properties. Lastly it keeps its sealing properties for the indicated lifetime of the sealant within its service environment and conditions.
