I want to replace my current suspended timber floor with a hardwood floor and also to install appropriate underfloor insulation. (Under the current floor there is a void and then mud.) For me the insulation is most important. I’ve read the relevant NSAI standard on energy efficient retrofitting, so I think I know what I need. Most of the web sites I’ve seen focus on supplying and fitting the floor but not on the insulation. So would it be better to get separate contractors? In which case, any recommendations? Or can anyone recommend contractor(s) who can do both the carpentry and install the insulation? (Dublin South area.)
