I've got an extension (kitchen) that is very cold. When it's warmed up it then looses it's heat far too quickly once the rads/oven are turned off. I want to reduce heat loss.
The 3 external walls are cavity brick with normal sized double glazing on 2 walls. The floor is suspended timber (half the floor area is insulated underneath, the other half is on my list). The ceiling is plasterboard and then an external flat felt roof. Floor area is about 5x5m, butted onto the back of the house. There is a huge amount of heat loss from the extension that I want to reduce. I suspect most is through the ceiling, and I suspect it's not insulated (old extension). I've got a small cable camera in the post to poke into the void and have a look around. Assuming it's not insulated for now.
Although the felt does need replacing at some stage, probably not for a few years. What's the least intrusive method for adding insulation in there? There is one light fitting in the middle of the ceiling. I can't access it from the house side, so it's got to be through the light fitting or externally - prefer internal is possible. Can you get insulation blown into spaces like this? Any other alternatives? Thanks.
