Fire Rated Ceilings: A resident’s guide

Can I install downlights, ducted air conditioning, ceiling exhaust fans or manholes in my unit ceiling?
Well yes… but you need to be very careful if your ceiling designed to have a “resistance to the incipient spread of fire to the roof space for a period of not less than 60 minutes”.
Fire rated ceilings are an fire safety measure, designed to slow the spread of fire from one part of the building to another.
