More underfloor progress

Normal underfloor heating installations might use a concrete screed but because of the wooden joist construction which is dictated by the fact that we are building a log house, we have to put in plywood trays on battens, 50mm of Cellotex FF grade insulation (this is slightly denser than normal Cellotex to help the pipe holding clips stay in place) and then use a pug mix of soft sand and cement to cover the underfloor pipes. This is a bit more laborious than other methods of underfloor heating installation. We also went this route because we did not want to loose any ceiling height.
