Hi guys.
I have just bought a set of downlights from Wickes.
They each require a 65mm hole in the ceiling and they aren't enclosed.
Can these be legally installed in a 30min fire barrier ceiling without a fire dome?
.
What about an upstairs ceiling through to the loft?
Cheers.
Tests have shown that downlighter holes do not reduce the effectiveness of a 30-minute plasterboard ceiling. 30 minutes does not constitute a barrier between different fire compartments, so if you don't have different compartments, i.e. the ceiling is not in a flat, or over an integral garage, or in a house of more than 2 storeys etc, you don't need firehoods or fire rated fittings.You already know the answer, so why ask?
If the ceiling is a fire barrier you must install fire-rated fittings or witches hats.
It's foolish even though there is absoloutely no point in doing so?
part C is not a consideration
Is there insulation above the lights , if so rigid hoods are required
It doesn't meet the definition of a "hood", but it is rigid.So these are illegal then ?
That's true.And your suggesting that regulation prevents the old fashioned method of simply clearing insulation around the fitting?
It's not up to him.(if thermal loss isnt an issue for the home owner).
23.—(1) Where a person intends to renovate a thermal element, such work shall be carried out as is necessary to ensure that the whole thermal element complies with the requirements of paragraph L1(a)(i) of Schedule 1.Do remember that the op is talking about his existing home, not a new build or extension subject to building control inspections that incorp the full rule book to cover the elements of regs that would apply to a bcs project.
How?
A standard downlighter will withstand fire for about 30 mins, the same amount of time as a standard plasterboard ceiling.

Absolute dribble.
