Load-bearing fire-stopping compounds are a type of construction material that is designed to prevent the spread of fire and smoke through service openings, and horizontal and vertical penetrations in walls, and floors of a building. They can also serve as structural support or as a substitute for other materials when used in the construction of riser cupboards.

These compounds work by expanding when exposed to high temperatures, filling the opening through which the fire or smoke may pass. In doing so, they create a fire-resistant barrier that helps prevent the spread of fire, giving occupants more time to evacuate the building.

Load-bearing fire-stopping compounds are used widely in construction projects where fire resistance is essential. For instance, they can be used to protect riser cupboards, which are critical service shafts that can affect the entire building if not appropriately protected.

When selecting a product, it is essential to check its fire resistance level and ensure it meets the requirements of the local building and fire safety codes. By doing so, you can be sure that your building is adequately protected from potential fire outbreaks.

The critical role of load-bearing fire-stopping compounds in protecting buildings against fire cannot be overstated. These compounds play a significant part in maintaining the fire integrity of a compartment wall or floor. In the event of a fire, load-bearing fire-stopping compounds can provide up to 4 hours of fire resistance before the fire breaches the barrier.
