Insulate a Concrete Ceiling

Post by teddy » 20 Dec 2010, 11:38

Hi, own a 1920 house that previously had a flat roof when in the 60's a pitched roof was added. The ceiling consists of a 300mm thick concrete slab and I cannot insulate it on the inside because the ceilings are ornate and an original feature.

Should I lay fibre wool on top of the concrete? Will it make much difference to the insulation properties of the house? What options do i have?

It could make a difference if you insulate. I would try a rigid insulation board like Celotex of Kingspan. You have to be careful to ventilate with insulation to prevent condensation points. Im no expert but I guess it would be ok
