Room is 3 meters high in the middle, and roof slopes down to floor. Room is 4 meters wide and 9 in length. There is small window in the non sloping wall at end of house. This wall is wattle & daub lined with 1/2'' fibreboard on the inside. At present room is "warmed' by a single 4'' steel pipes from ancient but wonderful battleship style central heating. I wish to leave oak roof trusses exposed. Half of the ceiling is currently plasterboard over a woolly black rug mixture. Under this is 1/2' fibre board on top of which is roofing felt and Kent pegs. The other half of the ceiling is just the fibreboard.
I've identified Celotex as a useful insulation that comes in a max thickness of 70mm. However at this thickness I lose the effect of the roof trusses standing proud of the plasterwork. Celotex has thinner products going down to 25mm but will it be any use this thin? Is it worth ripping down the old woolly stuff and replacing with Celotex? Is Thermal Insulation Plasterboard an alternative? This is a laminate I can plaster over but includes an insulating membrane. Are its insulating properties irrelevant as roof insulation?
Any advise on getting the room warm... and yes I'm going to put decent rad's in, although it's a nightmare cutting threads in to the old steel pipes.
