Newly cavity wall with thermalite inner - I'd like to use insulated plasterboard for better insulation but also as there is a steel I beam face set in it. Due to other features (window reveals etc) I've got a total 40mm max from the wall surface to play with so that rules battens out, unless I just use std plasterboard and cut up insulation between the battens.
Any thoughts / suggestions as to which is best way, is there a proven way to fix insulated PB direct to the Therms?
