Hi guys,
I have a 1930s bungalow up the coast. It was originally weatherboard now covered with Tyrolean render which is being renewed. Due to downpipe and guttering problems (now fixed) it had developed bad damp and rot in the subfloor in one room. The entire floor has since been removed and has all been replaced with new joists bearers, t and g chipboard etc. The space between the floor joists will also be celotexed. New studs have also been sistered into the walls where necessary. I am confident that all the damp issues have now been resolved but want to know the best methodology for refinishing the wallls. I was going to celotex with 50 mm then use foil backed plasterboard but do you think I also need a polyethylene DPM over the studs before the foil backed plasterboard or not? Should I ensure a gap between floor and start of plasterboard or fit tight all round? Any advice welcome. Many thanks Bron
