Active Expansion

When exposed to extreme heat, the membrane rapidly expands to form an insulating barrier layer. This reaction is triggered by intumescent technology built into the material.

Thermal Shielding

The expansion creates a dense, heat-resistant barrier that prevents flames, radiant heat, and hot gases from reaching the insulation and structural layers below.

Roof Preservation

By blocking thermal transfer, the membrane helps maintain the integrity of the roof deck, preventing ignition of combustible materials and structural collapse.

Fre Safety Layer

Bridgehill FireBlock Membrane functions as a fire safety layer, protecting roof structures from wildfire heat and wind-driven embers.
