In the opinion of the BBA, a roof incorporating the system will be unrestricted under the national Building Regulations in the following circumstances:
• Protected or inverted roof specifications, including an inorganic covering listed in the Annex of Commission Decision 2000/553/EC
• a roof garden covered with a drainage layer of gravel 100 mm thick and a soil layer 300 mm thick
• irrigated roof gardens, green roofs and brown roofs.

The designation of other specifications should be confirmed by reference to the requirements of the documents supporting the national Building Regulations.

When classified in accordance to EN 13501-1 2007 Triflex ProTerra Solvent-Free achieved a rating of Euroclass E.

If allowed to dry, plants used may allow the spread of flame across the roof. This must be taken into consideration when selecting suitable plants for the roof. Appropriate planting, irrigation and/or protection must be applied to ensure the overall fire-rating of the roof is not compromised.
