Jilly Posted October 20, 2020 Share Posted October 20, 2020 I'm getting overloaded (emotionally, that is!). Please keep things simple.. On our stable conversion, the existing floor is 150mm concrete slab. The architect's technician specified: T & G floating floor 80mm celotex with 22mm DPM (linked to DPC/RIW/tanking as minimum to get the BC regs passed and achieve u value of 0.22 However, now the builders are here it looks like we have 2 courses of bricks to Finished Floor level, which is 150mm. Not sure exactly how this discrepancy has happened... I'm wondering how to improve the floor from that specified. Will this small amount of insulation make UFH perform poorly ? (wanted it from a design and comfort aspect) Would we be better off improving the floor insulation and having radiators? Link to comment Share on other sites More sharing options...
