At Envirograf, we are committed to developing products which exceed the minimum requirements of the Building Regulations. Our products are designed to increase the fire resistance of every aspect of a building to a point where both lives and the building itself can be saved in the event of a fire.
Given that the fire resistance of an entire building is based on the fire resistance of its constituent parts, holes in any element of the building will compromise the integrity of the building as a whole. The same can be said for doors, as an open door provides no fire resistance at all.
It is in circumstances such as these that the need for passive fire prevention arises.
