FIRE Stopping
DDF FIRE LTD
What IS Fire Stopping?
Fire stopping involves sealing gaps and openings in fire-rated walls, floors, and ceilings to maintain the integrity of fire compartments. This practice is crucial for preventing the spread of fire and smoke between different parts of a building, thereby enhancing occupant safety and complying with building regulations.
In England, fire safety in buildings is governed by Approved Document B of the Building Regulations. This document provides guidance on measures to reduce the risk of fire and ensure safe escape routes. It covers aspects such as means of warning and escape, internal fire spread (structure and linings), external fire spread, and access for fire services. The document is updated periodically to reflect changes in fire safety standards and practices.
Examples of applications:
Service Penetrations
Sealing around pipes, cables, and ducts passing through fire-rated walls and floors.
Structural Joints
Addressing gaps between building elements to maintain fire compartmentation.
Expansion Joints
Sealing joints that allow for building movement while maintaining fire resistance.
