At first sight, a solar rooftop system may seem to run flawlessly for years. But the real risk lies beneath the surface. Installation errors and material ageing can trigger fire — sometimes in the first year, sometimes after 12 or 15 years. Only a non-combustible layer in the roof build-up stops fire from spreading and keeps your property insurable.
Cyber attacks … and roof fires? The EU’s new NIS2 rules demand that critical companies address all risks – including physical ones. Learn how a non-combustible roof coating safeguards facilities and supports NIS2 compliance.
Rooftop fires don’t start in the roof itself, they start in failing solar components. Connectors, cables and inverters are weak points that can ignite a blaze. AllShield ensures that even if these failures happen, your combustible roof will not catch fire.
Roof fires with PV systems can scatter dangerous glass and EVA fragments, harming people and property. Glass and Plastic based panels are the main source of this debris. AllShield explains why only a non-combustible roof build-up makes solar roofs truly safe and insurable.
AllShield Blue is now FM 4484 Approved — the world’s first coating that makes roofs fire-safe and insurable under PV systems. A breakthrough in solar roof safety.
European research confirms: rooftop fires spread because of combustible roofs. AllShield makes roofs inherently safe and insurable — even with solar panels.
FM and other insurers use FM standards to judge if combustible roofs with PV are insurable. ZAG testing proves AllShield BarrierSheet makes them functionally non-combustible, giving engineers the certainty to approve safe, insurable solar rooftops.
Flat roofs across Europe face different fire safety rules—with and without PV. From EN 13501-5 (t1–t4) to CLC/TR 50670, VdS Germany and Italy’s 2025 PV law. Discover how AllShield BarrierSheet, an A1 non-combustible cover board, complies in all EU + UK scenarios.
Gypsum cover boards have long been used for roof fire protection, but they are heavy and time-limited. AllShield BarrierSheet is thinner, lighter, non-combustible and tested under PV fire scenarios—making it a proven solution for today’s flat roofs.
PV fire risks don’t stop at borders. In Austria hail, in Spain heat, in Poland rapid installs, triggers differ, but spread is always through combustible roofs. AllShield BarrierSheet cover boards stop fire penetration and make solar rooftops insurable across Europe.
Electrical faults in PV are inevitable — but roof fires are not. ZAG testing proves: with AllShield BarrierSheet, even old combustible roofs become non-combustible, safe, and insurable for solar.
At ESFSS 2025, ZAG, Istituto Giordano and global researchers confirmed: PV faults are inevitable. But only non-combustible roofs stop them from escalating into catastrophic fires. AllShield BarrierSheet & Blue deliver the protection insurers demand.
