I am thinking about building a laundry chute from landing to uitlity room beneath. This ends up being a poorly sealed vertical duct, perfect for transmitting fire between floors. Anyone know how this can be done to satisfy regs ? Cheers, Simon.
AFAIK, it will need a fireproof door at the top, with a spring closure.

Intumescent seals on self closing doors or an intumescent baffle in the chute

So, what's the difference to the vertical ducts in a warm air heating system? They don't have intumescent baffles or spring loaded vents.

A bit more information needed. What kind of building (hotel, flats, within a single house)? How many storeys?
If this is in a "normal" house i cant see how it is affected by an regs. A fire can go straight up the stairs if it cares to. There is n requirement to fireproof the downstairs ceiling in my little semi, if choose to cut a hole in my kitchen ceiling so that the wife can pass m tea up to me thats entirely up to me. Now if it went from the landin into an integral garage that would be different as there is requirement to fireproof the garage. Otherwise I reckon you can do what you like
