Fire-rated partition walls are non-negotiable on commercial schemes — yet they are also one of the most misunderstood elements of interior fit-out. “Fire board” on a drawing is not a specification; a tested system build-up is.
FD30 and FD60 in plain language
These ratings describe how long a partition will resist fire spread in a standard test. FD30 = 30 minutes, FD60 = 60 minutes. Your building control or fire strategy document dictates what is required where.
Common failure points
- Unsealed penetrations for cables and pipes
- Incorrect board type or insufficient layers
- Non-rated doors fitted in rated walls
- Partitions stopping short of the slab without fire stopping to structure
