Hi all,
Quite a few posts on this area already I know but can't find anything about this specific question.
We've moved into a 1920's solid walled place that gets cold in the winter (surprise surprise) even with new central heating up to full. The radiators are old mind, and we're having those changed for newer efficient ones asap. Also had draughty old front and back doors, both of which've just been changed too.
The walls are pretty aesthetically crap and whilst the plasterwork's solid it needs reskimming. We though that at the same time we'd insulate the internal walls, especially as we were also changing the rads that are mounted on them too. But our plasterer recommended that there were a number of ways to do it; dot and dab regular plasterboard and let the air gap act as an insulator or put up thermalboard.
He seemed to think that given the changes that we've already made (doors) and are going to make (more efficient rads) that regular plasterboard dotted and dabbed would be sufficient. But having read a bit about this I'm not so sure. We did talk about thermalboard and whilst it'd add only about 6% to the overall bill it will mean it'd bring the wall beyond the level of the windowsills. But couldn't we just add wood to the sills, filler and re-paint?
Any thoughts on the best way forward much appreciated!
