What fire strategy is used for multi-storey timber buildings?

Multi-storey timber buildings typically use one of three fire strategies: full encapsulation (all timber protected by fire-rated plasterboard, timber not exposed — simplest for approval), partial encapsulation (some timber exposed with additional sacrificial layers calculated per EN 1995-1-2), or engineered timber performance (exposed mass timber with calculated charring rates demonstrating adequate residual capacity). Buildings above 6–8 storeys generally require sprinkler systems regardless of structural fire strategy.

Buildings above 6–8 storeys generally require sprinkler systems regardless of structural fire strategy. Compartmentation, escape routes, and firefighter access follow the same principles as for any material.
