Hi both, thanks for the replies. In my instance do you think it would be advisable also putting some internal insulation on the external facing walls (as well as insulating the floor and installing UFH)? Maybe 50mm as Jayc89 suggests? I’m concerned if I internally insulate I’d be trapping moisture and causing damp issues. I did first start thinking to do this but stopped after I read so many negative views about it possibly causing damp. Thanks

Hi, I’ve purchased a detached Victorian property (c1900) and we’re about to embark on a renovation project. I’ll probably have a number of questions but thought I post the first one on here To the rear of the property is a ground floor extension, c7 years old with wet underfloor heating. One of the rooms at the front of the house, adjoining this has old quarry tiles which look like they’re laid on a small layer of screed and just soil (maybe even just soil). One of our aims is to make this room warmer and we’ve asked a builder to extend the underfloor heating system. Plan is to dig up the floor, lay hardcore (100mm), a damp proof membrane, concrete (125mm), 100mm celotex, then the UFH pipes, then screed. Does anyone see any problems with this method, especially with the potential to push damp into the walls? Ps we’re planning on re-laying the quarry tiles which I’m told are a good conductor for UFL, anyone have an opinion on this as well? many thanks brett
