What is Firestop fireproofing?

A firestop or fire-stopping is a form of passive fire protection that is used to seal around openings and between joints in a fire-resistance-rated wall or floor assembly. Firestops are designed to maintain the fire-resistance rating of a wall or floor assembly intended to impede the spread of fire and smoke.

Is passive fire protection a legal requirement?

PFP provision is required in all buildings, whether domestic or non-domestic. Every service that is installed in a building, such as water pipes, electrical sockets, cable trunking and lighting units, can compromise the fire resistance of a room by creating openings in its walls, floor and ceiling.

Why do fire-stopping products have to accommodate movement?

In many applications, fire-stopping products have to accommodate movement of the services or joints in everyday usage. Sealants used around hot water pipes, or chiller pipes, can be subject to expansion, or contraction of the pipework that will produce both tensile and shear loads on the product.

What is a firestopping board?
