lookseehear Posted November 24 Share Posted November 24 I think IceVerge covers this in the video, with the main points being you can use standard gypsum plasterboard but don't use latex based paints that will seal it all up. On the point of only insulating 1st and 2nd floor, it would probably make sense to try and remove and refit the coving if you can. Link to comment Share on other sites More sharing options...

If I were using flexi WF (c50kg/m3) I would (and indeed did) use Intello. Can i ask what the logic is that drives that decision? Moisture-buffering due to the density.

Ground floor has some beautiful age old coving which other family members want to retain. It's theoretically possible, but may make airtightness harder to achieve and, of course, you loose the benefits of the insulation downstairs. It may be possible to buy the same cornice pre-made and install that, but if not then there are companies that will cast an identical replacement for you. 10 hours ago, ab12 said: would you cover this with standard gypsum plasterboard OR wood wool board? Standard plasterboard is OK provided you don't paint it with regular vinyl paint. Link to comment Share on other sites More sharing options...
