    Hi All,

    I am tying to decide which is the best option for sub flooring for my house. I will have underfloor heating downstairs and rads upstairs.
    I had a contractor out for both 'liquid screed' flooring and dry screed flooring. The liquid screed guy said I would get 110mm insulation in the downstairs, the other guy said 100mm, they both checked floor heights. I would like to get as much insulation in as possible.
    Some say liquid screed heats up quicker, but that means it would also cool down quicker, and that it get in around the underfloor pipes better, but that its more prone to cracking, but it is better for tiling as it is more level and I intend to tile all down stairs, that the dry sreed floor retains the heat better and is less prone to cracking.

    Any thoughts or advice as to which is the best option for me, dry screed was about E400 cheaper approx.

    Thank you

    Trying to make the saem decision myself at the minute. What did you go for in the end?

    does anyone here have underfloor heating with self levelling screed - how do you find it?

    likewise anyonie have it with sand and cement?

    Still thinking about, but leaning towards the 'liquid screed', I am told most of the cracking was teething problems, whos mix was used, and the contractor, five of my mates have used liquid screed in the last 3/4 years and no problems.
    I am tiling downstairs so I want to go with which will be most 'level'.
    As for holding heat, IMO heat rises, I have good insulation, siga tapes etc and heat recovery, so I am hoping to cut down on the amount of heat the underfloor will have to generate.
    I am still open to either method, just waiting for that fact or comment that swings you one way or the other.
