Constructed from materials of limited combustibility

Concrete (cast in-situ/planks etc)

Consider older building construction (e.g. Lath & plaster g ( g pconstruction).

Timber Floors FR measured from underside

Lath & plaster construction – unlikely to provide even 15 minutes FR without additional protection

No timber floors – existing buildings
