Insulation behind plasterboard

treascon

Has anyone any suggestions on how I can insulate behind plasterboards which are dabbed to the wall? The walls are built using ICF and the problem is that air is coming down from the roof space behind plasterboards and out at switches, sockets, skirting, etc. It is also cooling the floor and the underfloor heating can't keep up. I have looked into pumping foam insulation behind the boards but as far as I can make out they all expand and I'm worried it would push the plasterboard off the wall. All the rooms are fully finished and decorated and the budget is very tight so I need to find an economic solution. I was considering drilling small holes near the top of the wall and using the cans of expanding foam but not sure if this would work.
Any suggestions welcome. Thanks.

Expanding foam will burst out the boards so that is not an option.

I looked at a house in Ennis with problems with the external plaster with this system. The builder is gone burst and gone into hiding. The word on the grapevine is that he is in trouble (BIG TROUBLE).

I believe that a new political party is going to address this in their manifesto and call for interest free loans for repairs to houses built by these con men. The political partys convention is on the 11 of Feb. So I hope it will get passed.

Also. this system was approved by the Irish agrement board so should you sue them????

look, if you cant post on topic and refrain from suggesting that someone should instigate legal proceedings then you wont post here at all.

Im getting tired and bored now at this stage. I have done my best to help you but it appears that the advice given has fallen on deaf ears.

ive been thinking about doing this also,but in my case it would be between mass concrete wall and plasterboard which is battened,surely theres insulation oam that doesnt expand too aggressivly?

You could check out the ex foam from the tec7 range, it stops expanding on contact, so will not distort the boards,

That sounds very interesting indeed,Martin you may have saved me a lot of sweat and dust!,will check it out immediatly

Forgive me if I'm missing the point here; if the walls are ICF construction surely they're already insulated and your problem is cold air sinking form the roof space = check insulation in the roof space rather than walls???
