Protecting the lifeline: The key role of fire-resistant silicone sealants in building safety

In modern buildings, fire safety is a top priority in design. When a fire occurs, the speed of the spread of fire and smoke often determines the extent of casualties and property losses. Among them, building gaps, pipe penetrations, curtain wall joints and other parts often become hidden channels for the spread of fire. Fire-resistant silicone sealants are born to solve this key problem.

Fire-resistant silicone sealant is a specially formulated elastic sealing material with excellent weather resistance, adhesion and critical fire retardant properties. When exposed to high-temperature flames, it can quickly expand to form a dense, hard carbonized layer. This carbonized layer is like a solid barrier, effectively blocking gaps, preventing flame penetration, heat transfer and the spread of deadly toxic smoke, and buying precious time for personnel evacuation and fire rescue.

Its application range is extremely wide: curtain wall joints of high-rise buildings, expansion joints between floor slabs and walls, fireproof sealing of cable/pipe penetration holes, perimeter sealing of fireproof doors and windows, protection of steel structure nodes, etc. Selecting high-quality fireproof silicone sealant that complies with national and international fire protection standards (such as GB/T 24267, UL 2079, etc.) is a key link in ensuring the integrity of the building’s passive fire protection system. It builds an invisible “lifeline” for building safety and is a veritable building safety guard.
