Nassboards XPS Boards Floor Underlay Thermal Insulation Underfloor Heating - 22 x 10mm (15.8m2)

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. Thanks Nassboards will definitely be using again 👍👍

I bought this thinking that might not be working, but a bit of insulation is never bad thing, eh?Turns out this is truly amazing product and retains warmth and doesn’t allow that much energy loss.Really easy to cut and install.

Found these boards to be easy to cut and now the floor is down it feels warm and is quiet when you walk on it

Lovely and warm in the summerhouse
