What is non intumescent fire caulk?


One kind of fire-resistant sealant used to fill cracks, joints, and penetrations in fire-rated walls, floors, and ceilings is called non-intumescent fire caulk. Non-intumescent fire caulk preserves its integrity during a fire and stays in its original solid shape, unlike intumescent fire caulk, which swells and expands when subjected to high temperatures.

Non-intumescent fire caulk is composed of silicone, latex, and polyurethane, and it can usually endure several hours of exposure to high temperatures. In structures where fire safety regulations must be followed, such hospitals, schools, and commercial buildings, it is frequently utilized.

This kind of fire caulk is especially helpful for filling in spaces around penetrations such as ducting, plumbing, electrical wiring, and other areas where smoke and flames could otherwise enter a building. To improve fire safety, non-intumescent fire caulk is also used with intumescent products.

It's crucial to remember that, in order to guarantee appropriate performance in a fire situation, the particular type of non-intumescent fire caulk used should be selected based on the needs of your individual application and fitted in accordance with the manufacturer's recommendations. To make sure the fire caulk lasts a long time and stays intact, it should also undergo routine maintenance and inspections.
