Fire Safety

In the opinion of the BBA, a system comprising a 12 mm thick gypsum glassrock roof board, primed with Starcoat PMMA P Primer and coated with Starcoat PMMA (grey) reinforced with Starcoat PMMA Fleece, can be classified as BROOF(t4) in accordance with BS EN 13501-5 : 2005.

In the opinion of the BBA, a roof garden incorporating the system, covered with a drainage layer of gravel 100 mm thick and a soil layer a minimum of 300 mm thick, will be designated as BROOF(t4).

In the opinion of the BBA, when the system is used in irrigated roof gardens its use will be unrestricted under the requirements of the national Building Regulations.

If allowed to dry, plants used in a roof garden may allow flame spread across the roof. This should be taken into consideration when selecting suitable plants.

The designation of other specifications should be confirmed by: England and Wales — test or assessment in accordance with Approved Document B, Appendix A, clause A1, Scotland — test to conform to Mandatory Standard 2.8, clause 2.8.1(1)(2) (1) Technical Handbook (Domestic). (2) Technical Handbook (Non-Domestic). Northern Ireland — test or assessment by a UKAS-accredited laboratory, or an independent consultant with appropriate experience.
