has anyone used it? At the moment there are a few brands competing in this market of uncoupling / underfloor heating combo's, but this ditra duo claims to have a special thermal fleece backing that insulates and pushes 80% of the heat upwards. I'd be interested to know how that compares to an insulation board? Potentially makes this product more cost effective if it can be laid direct to the sub floor. It also sound deadens by 50% to the human ear
