On PV roofs we keep meeting the same question: how do I get a non-organic layer to the place where the fire load of a fault arrives, without compromising the roof build-up? The answer differs from roof to roof. That is why we work with three clearly defined lines, each with its own position, installation method and documentation.
We supply per project. That means a concrete proposal with the selected board or system, the associated data sheets and classifications, the detailing of seams, outlets and upstands and an honest list of points still to be agreed with the structural engineer or roofing contractor.
