Cavity barriers and fire stops are both passive fire protection components, but they address different weaknesses in the compartment line.
A cavity barrier is installed inside a concealed void, typically the gap behind external cladding, inside a timber frame or in a roof space, to block fire and smoke spread through that continuous cavity. Barriers are placed at compartment boundaries, at floor junctions and at building envelope edges. The ventilated cavity fire barriers hub covers the full Tenmat product range for this application.
A fire stop seals a specific hole where a pipe, cable, duct or conduit passes through a fire-rated wall or floor. That penetration creates a direct path for fire to bypass the compartment line. Pipe fire sleeves, intumescent seals and fire collars close individual penetrations to the same fire resistance period as the host element.
