Underfloor heating and underlay

    I have put in underfloor heating (in screed) which I intend finishing over with an engineered wood. I have a concern about certain types of underlay acting more as an insulator rather than easily allowing heat through. In people’s experience, what is the best underlay to us, cork, rubberised or other material? I am not overly concerned about noise from walking on the floor.

    Our engineered wood was glued to the screed (glue that is ok with UFH) and we haven't had any problems.

    I would be very interested in this one, I have u/f heating on both floors with a screed and will be at the flooring stage in a couple of weeks.
    I have heard conflicting answers on what type of flooring to use.
    Some say I HAVE to use engineered flooring, others say semi- solid is not a problem and I didn't even think about the underlay !!
    Any help , much appreciated, Thankyou

    there are low tog underlays available especially for this purpose. google underfloor heating underlay. look for the lowest tog value you can get as this can make a massive difference. i think quicktherm has the lowest tog rating i have seen

    A friend of mine has both engineered and semi solid in his house with underfloor heating. He has had no problems and did not use any underlay. Just glued directly to the screed.
