Fire Protection for Solar Roofs

Fire Membrane for PV Panels on Any Roof Type
Solar panel fires pose a serious risk to buildings, especially when combustible insulation is present. Installed beneath any rooftop solar system, FireBlock expands under heat to block flames, radiant heat, and gases before they reach insulation or structure. For both new construction and solar retrofits.

Bridgehill FireBlock Products

Fireblock Membrane Bridgehill Fireblock Fire Proof Membrane (1)
Fireblock Membrane
FireBlock is a fire-resistant sandwich membrane with a multi-layer construction and a FireBlock core technology. The core is engineered to react to high thermal exposure while the outer layers provide mechanical stability and compatibility with standard roofing systems.
Adhesives And Tapes Bridgehill Fireblock Adhesive For Fire Proof Membrane (1)
Adhesives And Tapes
High-temperature-resistant adhesives and tapes are used to bond seams and overlaps, ensuring system continuity under fire conditions. The products retain adhesion and sealing performance at elevated temperatures, eliminating the need for mechanical fasteners.
Soap Bridgehill Fireblock Soap For Fire Proof Membrane
Soap
The installation soap is a surface preparation and installation aid that removes grease and contaminants to achieve consistent adhesion. The product is environmentally friendly and non-toxic, posing no risk to the surrounding environment.

Research & Engineering

Bridgehill Engineering Lab
Developed by Bridgehill’s R&D team, FireBlock is a fire-resistant roof membrane engineered for solar PV systems and modern roofing structures. Suitable for both flat and pitched roofs, it can be installed above or below the waterproofing layer in new builds or solar retrofits. When exposed to high heat, the membrane expands to form an active fire barrier that helps block flames, radiant heat, and airborne embers. This protects insulation and structural components beneath rooftop solar installations. FireBlock provides solar installers, roofing contractors, and engineers with a practical solution for improved roof fire protection, wildfire resilience, and fire safety compliance.

How much does albedo really matter for solar energy production?
Research from NTNU, international studies, and Bridgehill Engineering Lab shows that surface reflectivity can make a measurable difference in bifacial PV performance, delivering up to 10–20% higher annual energy yield on reflective surfaces. This article explains how albedo works and why it matters for system design and return on investment.
Quantifying the Albedo Effect for PV Modules

What Is the Albedo Effect?
The albedo effect describes how much light a surface reflects. In solar energy systems, especially bifacial solar panels, higher reflectivity can increase energy yield. Learn how albedo impacts solar panel performance and system efficiency.

FireBlock
The albedo effect refers to the ability of a surface to reflect sunlight. For bifacial solar panels, which generate energy from both the front and back sides, this reflectivity can significantly impact performance. By increasing the amount of light reflected onto the rear side of the PV modules, high-albedo surfaces can boost total energy output especially during summer months when solar exposure is highest.
