Fire in a building is always unplanned and can be devastating, both to the property and also its occupants. That’s why passive fire protection is so important – it can not only help to protect the integrity of the building but also provide crucial escape time. Firestopping is an essential element in passive fire protection and there are a range of different solutions for ensuring that protection levels meet expectations in any building.
What is firestopping?
Essentially, it’s a fire protection system for a building that is made up of various elements that are used to seal openings and joints. These are applied to fire-resistance rated wall or floor assemblies to provide complete passive fire protection. The purpose of firestopping is to re-instate the integrity of a fire compartment that has been breached, that can enable a rapid and uncontrolled spread of fire and smoke. Although small, these can have a significant impact on the fire resistance rating of structures. Firestopping can be used in a number of different openings, including control or sway joints, electrical and structural penetrations and junctions between fire-resistance-rated wall or floor assemblies.
The different solutions to firestopping
Sealant and coatings
Coatings can help to prevent the spread of a fire by resisting flames and forming an insulated char that protects the materials underneath. There are a range of different coatings available, such as an Intumescent paint. Sealant, too, can provide crucial protection by being used to seal penetrations within walls, partitions, fire rated door frames and glazing systems to improve fire resistance. Many sealants also provide acoustic benefits and most will last several hours if a fire does break out if installed to manufactures guidance.
Firestopping options for plastic pipes include pipe collars or wraps, which are water resistant and provide hours of protection. Pipe collars can be retrofitted over plastic pipe work where it passes through fire resistant walls and floors.
Penetration void fillers
These are specific materials that are available where compartment walls and floors have been penetrated as a result of something like multiservice installation, leaving voids that need to be filled in order to bring fire integrity /performance back to original standard.
Gaps and seals
Gaps in the construction of a building, as well as voids in compartment junctions and construction joints can allow fire and cold smoke as well as hot smoke to pass through and spread.
