Larger Service Openings

Fire Stopping Larger Penetrations

Fire stopping compounds are used within passive fire protection systems to seal larger service penetrations through fire-rated walls and floors.

They are typically mixed and installed around building services to create a solid fire-resistant seal within the relevant tested configuration.

The correct compound, installation depth and supporting construction must match the services and dimensions covered by the manufacturer documentation.

Installation

How Fire Stopping Compound Is Used

Compound systems are commonly specified where a robust fire stopping seal is required around larger or multiple service penetrations.

Mixed for Installation

Many compound systems are supplied as a dry material that is mixed with water before application in accordance with the manufacturer's instructions.

Forms a Solid Seal

Once installed and cured, the compound forms a solid seal around the services within the opening.

Multiple Services

Tested compound systems may accommodate cables, cable trays, pipes and combinations of services depending on the approved detail.

Specification

Choosing the Right Fire Stopping Compound

Check the complete penetration detail rather than choosing a compound by fire rating alone.

Wall or Floor

Check the supporting construction, its thickness and whether the tested detail applies to a wall or floor.

Service Type

Identify the cables, trays, pipes or mixed services passing through the penetration.

Opening Size

Check the aperture dimensions, seal depth and service arrangement covered by the system.

Tested Detail

Confirm the product, installation depth and service configuration against the relevant manufacturer documentation.
