Hello
The upstairs bay windows in my house are single brick and over time mould grows on the inside wall.
I was planning to insulate the area with 90mm Gyproc ThermaLine SUPER insulated plasterboard and bond the boards to the wall with Gyproc Dri-Wall Adhesive.
My concerns were:
1. do i need to strip the wall back to the bare brick?
2. do i need to treat/paint the wall to seal it before I fix the boards.
3. should i use wooden battons instead of Gyproc Dri-Wall Adhesive.
4. the insulated boards have a perforated layer covering the insulation - is this the vapor barrier? or should i just peel this off as it looks like it'll come off anyway!
5. I was going to butt joint the boards together. do i need to cover the joints with anything?
