Review: Very Good - Was apprehensive on the boards but stuck on a concrete base in my kitchen with flexi adhesive,Heat mat 200w, self leveller, anti crack mat then tiled in porcelain. Turned the thermostat on after 7 days, set on my iPhone & instant heat at 20degrees increased day by day to 22 and is nice & warm on the feet. Maybe wintertime I’ll take it higher but it’s took a very cold ground floor kitchen to a very nice pleasurable place to be.

I found a paint scraper best for trimming them rather than a Stanley knife. **Q: Want to use under vinyl click in garage with lumpy floor would this work?** A: I used it on a concrete floor which was slightly uneven prior to laying down ceramic floor tiles, my suggestion would be to even out any big/excessive lumps or apply some self levelling screed before fitting the boards. **Q: What is the insulating U-value for the 10 mm board?** A: No idea but they are made to go under electric heaters and I have them in the bath room and they work very well **Q: Can these boards be used on bathroom walls to tile on?** A: No these are not designed for wall tile installation ## Customer Reviews ### ⭐⭐⭐⭐⭐ Very Good *by M***C on 19 April 2020* Was apprehensive on the boards but stuck on a concrete base in my kitchen with flexi adhesive,Heat mat 200w, self leveller, anti crack mat then tiled in porcelain.
