Hello im converting the garage and im not 100% on the insulation to use.At first i was going to just use 2x2 with either rockwool or kingspan but ive seen the kooltherm boards from kingspan.These are the ones that have foam bonded to plaster board that you dot and dab.Would it be suitable for single skin outside walls? thanks
I'm considering doing the same thing and I'd also thought of using Kingspan. I was originally going to use battens with that in between like drylining a wall but to avoid the difficulty of drilling and plugging concrete my Da suggested I glue it with no-more-nails. I intend to do the sides first, then the roof to wedge it in place, then do the end sections, removable at the car door end and fixed with a separate door at the people door at the other end.
Then I was going to glue plasterboard to the sides. Your special bonded kooltherm kingspan will make that easier.
