Allshield Coatings says that the fire -resistant product can be installed under a new roof covering or applied to the roof material of existing roofs. It weighs 2.8 kg/m2 and is said to be a effective fire -resistant layer, so that the risk of fire spread is considerably reduced.
Dutch company Allshield Coatings BV has introduced a new fire brigade solution for flat roofs, making them suitable for PV system installation.
The barriers blue solution can be installed under a new roof covering. If an existing roof is in place, this can be applied directly to the roof material and then covered with a synthetic roof membrane.
“The barriers of Allshield serves as an effective fire -resistant layer, which considerably reduces the risk of fire spread,” the company said in a statement. “Thanks to the unique properties, even a lightweight roof structure can be safely equipped with a PV system. As a result, buildings that would otherwise not be suitable for PV installations can now be safely and efficiently equipped with solar panels.”

Barrierheet Blue consists of a fiber optic-reinforced coating, with a fire classification of A1, made from non-combinable materials. The dimensions are 950 mm x 2,000 mm, with a thickness of 2.4 mm. It weighs 2.8 kg per m2.
The company claims an unlimited lifespan, because it is not exposed to weather conditions and is protected by the roof covering.
“The barriers has also been tested by Kiwa-BDA for the NEN 7250: 2021 and was recently tested in Zor with Grunde Jomaas and his team,” said CEO Olivier Langejan PV -Magazine.
The barriers from Allshield has a fire classification of A1, so that roof systems with synthetic or bitumen roof covering perform better than the guidelines of NEN6063: 2015 for the entire roof structure, according to the company.
“Testing for the FM4470/FM4478 will start and will be completed before Q3 2025,” said Langejan.
