When it comes to passive fire protection, every second counts. In the event of a fire, controlling the spread of flames, smoke, and toxic gases is critical to saving lives and protecting property. Wedge India stands at the forefront of this mission as India’s largest manufacturer of Intumescent Fire Door Seal Strips, delivering high-performance solutions that meet both Indian and international safety standards.
With state-of-the-art manufacturing facilities and a nationwide distribution network, Wedge India supplies INTUR® Rigid and INTUF® Flexible intumescent fire seals that are trusted by leading door manufacturers, construction companies, and safety consultants.
What Are Intumescent Fire Door Seal Strips?
Intumescent fire door seal strips are specialized safety components fitted around the edges of fire-rated doors. Under normal conditions, they are slim and unobtrusive. But when exposed to extreme heat (typically above 180°C), these seals expand 20–60 times their original thickness, filling gaps between the door and the frame. This creates a barrier against the passage of fire, smoke, and hot gases.
