Cavity Barriers

Cavity barriers are an important part of passive fire protection, designed to help prevent the unseen spread of fire and smoke through concealed cavities within a building. By closing gaps within roof and wall cavities, they help maintain compartmentation and improve overall fire safety.

At FireSealsDirect, we stock the FIREFLY® Roof Cavity Closer, a fire-tested cavity barrier solution designed to close the void between the roof membrane and tiles at compartment lines. Suitable for use within roof spaces, it helps restrict the movement of fire through concealed areas while supporting compliant passive fire protection.

The FIREFLY® Roof Cavity Closer provides a reliable solution for protecting roof cavities and maintaining the integrity of fire compartments.
