I am converting my garage to a small home office. The internal walls are bocks and I want to clad them for insulation and appearance. I know I will have to batten the walls first, but because of my health I would find it impossible to handle the weight of plasterboard. I am probably looking for something that does not exist, but may be someone can confirm one way or the other. My perfect solution would be a very lightweight board probably about 10mm thick which I could glue to the battens but would have a smooth exterior finish that could be painted if needed.
Any help would be appreciated.
