As a reminder, vegetated claddings must meet the same fire resistance and behaviour requirements as other types of facades, as specified in the draft Royal Decree amending the basic standards (2022).

To date, there are no specific fire safety requirements for vegetated facades.
In a recent article on the fire behaviour of vegetated facades, the BBRI recommends measures to limit the vertical spread of fire along 'green' facades.
