Hi, I'm after a bit of advice regarding PIR boards.
I've got an existing garage conversion which was converted before we moved into the house. The room is almost unusable in the winter as it is so cold.
I know from having many people round to look at it that there is no cavity. I've now decided to sort it out myself so I thought I would use Ecotherm pir board (only because i can easily get it from local building supplier). Now the easiest was to do this would be to attach 1x2 battens and then attach the EcoTherm Eco Liner to the battens, skim, job done. The only thing is that they are really expensive.
So i then thought about using 2x3 battens and putting 75mm Eco-Versal pir board in between each batten, then cover with plasterboard and skim. Would this be an acceptable way of doing it and would it give the same amount of insulation as thermal plasterboard. This would be my preferred option cause it will be much cheaper.
