New solid floors

[cloughy513]

Hello everyone

I'm looking for some advice or people that may have done something similar.

I have recently moved into a new property (1910s) it is of solid wall construction and has solid floors (or as they feel at the moment floor freezers). We are planning on digging up all the floors downstairs so we can insulate them and install wet underfloor heating thought the whole house. at the same time we will also be looking to apply internal wall insulation to all external walls.

My query is would you insulate above or below the floor slab and what thickness of insulation would you go for?

if you have done it before is there anything you didn't do that you now wished you did?

Cheers

For UFH, you insulate above the slab, i.e. the heating pipe matrix is clipped directly to the insulation prior to the (75mm+) screed being laid on top.

I have similar property build and installed wet UFH, in my kitchen... it's brilliant. Wish I did the entire ground floor.

After laying concrete slab, I did 100mm kingspan, followed by 75mm liquid screed. This time of year, my floor is on low 24/7. That said never noticed a big increase in the bill, I think it's efficient, feels much more comfortable than rooms with radiators!
