Hello folks,
Just looking for a little guidance please. I am sure that this is something that many of you have come across before.
I am replacing the four existing downlights in the upstairs bedroom of our bungalow and am fitting Loceco LED units.
I have run into a problem inasmuch that above the ceiling plasterboard there is what appears to be 100mm thick Celotex insulation panels. I have adjusted the holes for the light fittings to the recommended 75mm but of course the hole is now a more or less solid 75mm by about 115mm thick. This means that the Celotex is stopping the spring-loaded arms from working as they should, i.e. coming down onto the plasterboard and pulling the light uptight against the board.
I wonder if the fitting will hold in the correct position or will I have to dig the Celotex away completely. I should add that there is no access to everything from above as it's all in the apex of the roof.
Many thanks for any input that may be offered.
