Fire Block Membrane
Pitched Roof – Under Roofing
The Bridgehill Fire Roof Membrane – Pitched Roof Under Roofing is a high-performance fire protection layer engineered for pitched roof constructions in wildfire and ember-prone areas.
Installed directly above the wooden roof deck and beneath the outer roofing layer, the membrane forms a sealed fire barrier within the roof assembly.
In the event of a solar panel fire, airborne embers, or external flame exposure, the membrane activates under extreme heat, expanding to block flames, radiant heat, and hot gases.
This prevents ignition of combustible insulation, protects load-bearing structures, and significantly reduces the risk of structural failure during wildfire events.
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.
Standalone Fire Defense
Bridgehill Fire Roof Membrane functions as a self-sufficient fire safety layer, even without sprinkler systems or active fire suppression — ideal for remote, off-grid, or wildfire-prone buildings.

One of the primary advantages of the Bridgehill system is that it eliminates the need to remove existing roofing. It is designed to be installed over your current roof, removing the requirement for expensive and time-consuming demolition.
The membrane acts as an intumescent shield. When exposed to fire from the panels, the material expands to create a thermal barrier that blocks heat transfer, effectively protecting the insulation below and keeping the roof intact.
The Bridgehill Fire Roof Membrane is highly versatile and compatible with most standard industrial roofing materials, including bitumen, foil, and asphalt-based roofs.
Yes, the product features documented fire resistance based on comprehensive full-scale tests, ensuring it meets strict safety standards for industrial buildings.
