Hi
I want to fix Kingspan Kooltherm K17 to a 9" solid wall in a small bedroom. Because the room is so small I will use 32.5 or 37.5mm (total) thickness board and fix it direct to the wall. I wonder if anyone could answer a few questions for me?
1) Should I use adhesive, (special) nails or both?2) I only need 2 boards and will tape the join between them. Will I need to have the boards skim plastered?
3) Do any of the well known building suppiers (Travis Perkins etc) sell them? I looked at planetinsulation but they have a minimum order of =A3200, which is twice the cost of what I need. I live in Surrey.Any advice appreciated,
David
