Hello, I would be so grateful if anyone can advise me... I am putting some 35W halogen downlights in my kitchen ceiling, annd trying to figure out if I should use fire hoods behind them.
I am in an attic apartment. There is currently a wood ceiling with exposed rafters and no insulation. On the other side of the ceiling there are the roof slates outside, that's it. We are putting plasterboard between the rafters and (still not putting insulation, just leaving an air gap), and we are fitting the halogen downlights into the new plasterboard.
The depth from the back of the plasterboard to the wood of the ceiling will be about 7cm. The lights themselves take up about 3-4cm.
My first choice would have beeb proper fire-rated downlights, but they all seem to be 11cm deep, which does not fit into the allotted space between my rafters. So the alternative seems to be to use the normal downlights, with the firehood. HOWEVER I am now receiving advice saying that ventilation is preferable to a firehood, and now I am confused!
Can anyone help? I would be very grateful.
