    HI all,

    I'm in the process of getting my extension signed off by building control and the only thing outstanding that's a problem is they're stating that the lintels above my garage doors (normal catnic cavity wall lintel) need to be fireproofed, even though they're on the outside of the garage door.
    They've suggested I line them with supalux or similar, although looking at this it's about £100 a sheet so not a cheap fix.

    Does anyone know if this is a normal request and if so are there any better ways of doing the job? Might have to have a look at fireproof paints and see if that's a better option.


    Thanks :)

    Normally a layer of 15mm fireline (fire resistant plasterboard) or two layers of normal plasterboard satisfies the BCO.

    Does the lintel support any wall, or just part of a roof?

    Can't use plasterboard as it's outside.

    The garage door is a roller shutter and is attached to the rear face of the opening.
    The lintels are supporting the front walls of the extension, a room above the garage.

    I've found a product this afternoon:

    http://www.fermacell.co.uk/en/content/wet_areas_1216.php

    The local merchants has it in stock and from looking at the specs it looks like it'll do the job, and it's much better on price, £19/sheet.
    There will need to be a join though as my opening is 2.6m and the sheet is 2.4m but hopefully that'll be OK.
