Prevent the spread of smoke and fire by sub-dividing cavities in your building
National building regulations state that cavities and concealed spaces must be sub-divided to prevent the spread of fire. Partition walls in houses and offices often stop at the ceiling, leaving a shared roof void. This allows smoke and fire to spread between rooms quickly. Cupboards and wall panels can also be shielded with fire barrier materials to protect specific rooms and walkways.
Fire barriers will form part of your fire risk assessment (FRA).
