PiperJ Posted October 25, 2023 Share Posted October 25, 2023 The ground floor of my project is concrete. I’m not having UFH. I believe building regs require me to have a DPM launder, 100mm Celotex with 75mm screen on top. I will be laying reclaimed wooden floorboards over. My question is regarding screed. Is there any type of screed that I could lay thinner that 75mm that would give the same amount of support? also what is the best type of screed to use?

Mr Punter Posted October 25, 2023 Share Posted October 25, 2023 Liquid screed can go down to 45mm. Link to comment Share on other sites More sharing options...
PiperJ Posted October 26, 2023 Author Share Posted October 26, 2023 Have been talking to someone today who recommended I use 150mm Celotex then click clack chipboard with the floorboards on that. Would save a lot of time. Any thoughts as to why I shouldn’t as I think it might be the way to go. Link to comment Share on other sites More sharing options...
Mr Punter Posted October 26, 2023 Share Posted October 26, 2023 Floating chipboard will work out and be cheaper. Use 22mm chipboard and glue the floorboards to it. Link to comment Share on other sites More sharing options...
PiperJ Posted October 28, 2023 Author Share Posted October 28, 2023 Thank you. I’m hoping the extra 50mm celotex will satisfy building regs not using the screed. Link to comment Share on other sites More sharing options...
