Flammability is NOT the issue. By themselves the products are known to be flammable. The REAL issue is whether any fire is contained to the one flat and not spreading to others. That is meant to be the emphasis in the design.

“The issue is about compartmentalisation,” he says. “Whatever cladding system you use, you have to incorporate fire stops at the line of each floorplate and every party wall around a dwelling to prevent fire from spreading up the facade. The current regulations are robust enough, but they have to be properly followed, and the architects drawings properly executed on site.

Be interesting to know if anybody has done tests using PIR insulation boards and comparing FR(which still contain PE) and PE type external cladding boards. Either they would show that selecting FR or PE would make little difference, or that only FR boards should be used with PIR insulation.
