Strips must be manufactured and tested in accordance with BS476 pt22 and BS EN 1634-1. 

Do fire doors need special hinges?

Yes, fire door hinges must be CE marked and made from a non-combustible material with a melting point of at least 800°C (such as brass, stainless steel and phosphor bronze). The size of the hinge fitted should be outlined in the fire door test, although the most common sizes are 100mm and 76mm. The CE and UKCA mark should be clearly displayed on the hinge.

What are intumescent hinge pads?

Intumescent hinge pads are fire-resistant pads that should be fitted behind the hinge leaf on both door and frame side. The intumescent material will expand when exposed to heat to seal fire doors to their frames and prevent the spread of fire. 

What are the advantages of intumescent hinge pads over traditional fire seals?

The main advantage of intumescent hinge pads is that they are designed specifically for the hinge area of fire-rated doors. Traditional fire seals typically work on the perimeter of a door, but hinge pads address the unique fire risks posed by the hinge gap, ensuring a more comprehensive fire protection solution. 

What is intumescent material?
