Potential problems with insulated plasterboard
Anonymous user 28/02/2024 - 3.58 PM
I want to fix insulated plasterboard (about 38mm) onto a solid wall with no cavity. The most recommended way is to fit 2x1 battens with dpc behind. But I don't want to lose this extra 1 inch floor space. Dot and dab is messy. If I use foam or similar adhesive...are there any potential problems with cold spots on the plasterboard wall or with condensation? The wall is upstairs not ground level.
Are you a tradesperson and able to answer this question?

Dot and Dab isn’t messy if done by someone who knows what their doing and is experienced. It’s the only method I’d recommend other than mechanical fix as other adhesives might not have the correct grab. It’s also the correct method to ensure walls are level and square.

This will depend on the thickness of the insulated board so here it is:
** If it allows, get a thinner insulated board and build a frame (as per your first choice) and you can also insulate in the space of the frame.
** Dot and dab is your next option.
** You can also use the foam adhesive (not expanding foam) but it will need mechanical fixings onto the wall too. Downfall of this is that you will be bridging to the exterior solid wall, therefore you will get some cold spots (depending on how many screws you put on)
Hope this helps

Why don't you put a waterproof sand and cement coat on the block wall tight coat and then cut the bottom of the sand and cement as a air gap then when dry put on the plaster board this will do it
