Hello and thank you for taking time to read this. I have a new outbuilding with cavity wall. Inside blocks are thermal ones. I need advice on whether to plasterboard then skim or carry out Plaster and skim. I understand for plaster, we need to put a mesh on the 'scratch' coat and skim over. Having plasterboard will take up undue space if going the route of dot and dab. Does having plasterboard help the place stay warmer? Drying speed is immaterial as I have lots of other work going on so having a wet plaster solution seems ok to me. In both cases, i need to get a plasterer to carry out the work so I thought it would be better to go for wet plaster all together and not use plasterboard at all? (except for the ceiling). Thank you for your advice and comments in advance.
