    Question Did you get under floor insulation in your home?

    ... and did it make much difference to feeling warm? With a govt subsidy and a time payment plan, we are thinking of getting the foam type of under floor insulation (pressed into the floor joists), rather than foil. Moisture proof ground sheeting is part of the installation.

    We have an older house, timber, with no insulation in the walls but plenty in the ceiling. Getting insulation in the walls is much more expensive.

    Thats on the to do list within the next few months.

    I know someone who has had it done last year, and the difference was really noticeable afterward, stops the coldness from coming up through the floor Expol is what was used, we are going to do the same.

    Looked into the govt subsidy - problem being, they wont let you install it yourself, they say you have to use a certified contractor to install it .

    Yep. Recently installed foam type underfloor as you describe along with black plastic on the ground.

    Do I feel warm? Yes.

    Evidence? Power bill has gone down compared to this time last year.
    There again I'm in a flat and brick construction and once again no wall insulation.

    Only heater is in the lounge.

    HTH.

    What a quaint 18th century idea, they called it "frigoric" the flow cold, a fluid substance to a warmer body, alternatively warm bodies had "caloric" which if it leaked away they became cold.

    Remember that house asked about in the original post was made of timber?

    Or did that point escape you entirely?

    And the point being what ??

    Our own floor, is only wooden T&G, you can feel the cold coming up through it, and the persons place I was at was the same. After the Expol was put in (or under as the case being) the rooms were warmer, less heating was required as the place wasn't so cold.

    When I was doing the walls last year in our kitchen, and the skirting was off the the walls/floor, there was a noticeable draft - the Expol works well.

    The house behind mine, built on a slope, is about 1.5 metres above ground level at the front.
    I just don't understand why the owner, who is forever potching around with minor DIY jobs, still hasn't blocked off the front. It would be a half-day job at max. Perhaps he likes listening to the Southerlies blowing under there straight off the Cook Strait.

    Yep. And I apologise but I felt the OP wanted actual experiences from anyone that had installed underfloor insulation on a timber floor.

    Talking about a concrete floor is somewhat different in my opinion.

    But to answer your question I suppose you could install foam insulation under a concrete floor. Whether you would get any benefit as in being warmer is another matter.
