I'm soon going to be insulating our new build, and want to dry line the inner side of the external walls downstairs. I'm trying to find out what the best way to do this is. I will be using 'warmboard' - platerboard with an insulation board all in one, for the dry lining.
I know these can be fixed directly to the block walls with a special mushroom fixing, but I'm wondering does any gap need to be left between the wall and the insulation to allow for air circulation? I don't really want to leave a gap unless it's really necessary as it's eating into room space.
thanks,
dj

. Seal the perimeter of the boards in particular the bottom with the compound. quote]
do you mean seal the back of the bottom area against the wall, or the frame piece actually touching the floor? Preume the edge of the board coming into contact with the floor?
thanks

dj01,
I am currently dry lining the external walls of my new build using 37.5mm insulated boards (Kingspan). Easiest way to fix then is using bonding compound (gypsum). It is a fairly quick process and much easier than I expected. Do NOT allow air to circulate behind the boards as this can cause condensation and mould problems behind the boards. Allow for a 10mm gap for adhesive. Seal the perimeter of the boards in particular the bottom with the compound. As far as I know it will bond to existing finished walls..
Boards are 40Euro each (8x4) and compound is 6euro/bag (1bag=2 boards).
