Hey Folks!
I'm shortly going to be installing a Central heating system - the client wants the boiler to go under the stairs.
I understand that this is permitted, given everything else being equal, if the understairs area can be proofed to withstand fire for 30 minutes.
Sniffin' around this site, it seems that either a double layer of regular plaster boarding or a single layer of the pink fireproof plaster boarding is sufficient.
The area concerned has a left hand side wall of either brick or block, a rear wall of brick or block, the wooden underside of the stairs and I'll have to pop a stud in to make a right-hand wall .... or board the stairs right down to florr level. Kinda assuming I don't have to board the brick/block - if I do, what's the advice on fixing?
The punter [ sorry, Valued Client!! ], has no desire for any addition finish to the board, if the above is ok. They also have no desire for the understairs to be boxed-in. [ So no skimming of boards and no door and front wall requirement. ]
Is that ok? - Tried to explain that flames 'reach out' for oxygen so uncontained could be an issue, but I'd seek advice.
The boiler will be 'sealed to room' but I assume it should still have vents for air to flow?
*Sneakin' in another question*......
What do I do with joints and corners? Is there a fire-proof jointing material? I assume metal screws aren't an issue, even though the heat conducts into the wood, by then the house will have fried anyway?
I'll be seeking advice of the boiler installer guy, of course. But would like my brain to be for-armed with info.
Ta!
