    Hello All.

    I've an "integrated" garage if that makes sense in a 4 bed semi D that I'm going to convert into a room. I've 3.5 inches I need to raise the floor by. Kango'd a small hole in the concrete to see what was below, no insulation.

    What's the best option, half inch insulation and three inches of conc or an inch insulation and 2.5 inch conc?

    Alternatively timber.

    Cheers for any thoughts.

    First they came for the socialists...

    Take it all out and insulated properly.
    75mm slab may be too slender and that’s the max you propose, you offer an option of 62.5mm concrete slab. I’d run a mile if one of my builders done that.

    You could put ridgid insulation and a 50 mm fast flow screed.
    Or else bond ridgid insulation to the floor then bond floor grade osb to the insulation provided the sub floor is level.

    It’s been converted to a habitable room.
    Will this build up, including the sub floor comply with building regulations?
