In my home Insulation

Billbo_Baggins

Ceiling/roof insulation. Can any one recommend a way to insulate a concrete ceiling. The room has a pitched ceiling and is very cold in winter. I can’t afford to loose to much in head height. There is no space above the ceiling as the roof tiles are laid directly on the concrete ceiling/roof. I do not have a problem with condensation at the moment and wonder if insulating the ceiling/roof might cause it. Your thoughts on the above would much appreciated. Regards Bill

For insulation to work effectively, it needs to be thick in order to allow for air pockets. The recommendation now is for 10 to 12 inches, though you can buy rolls thinner than that (intention being one roll goes between joists in the loft, and the other goes over the joists). Perhaps you could go halfway? I'd have thought it would be a case of building a frame connected to the ceiling, filling that with insulation, then plaster boarding over. I expect you'd at a minimum need to lose about 8 inches of headroom in all that. I doubt you'd get condensation, especially if you don't already.

How much height can you afford to lose? There are insulating products which perform better than fibreglass or rockwool but cost more. Try looking at something like Kingspan but you will need about 100mm thickness to have any real effect.

I have used polystyrene on a roll in the past, which made the walls feel warmer. You just use wallpaper paste and then wallpaper over it.
