Nassboards XPS Boards Floor Underlay Thermal Insulation Underfloor Heating - 16 x 6mm (11.5m2)

Covered 5m² concrete subfloor for underfloor electric heating, easy to cut. Already feeling the heat benefits and highly recommended using (though trade's people told me not to bother, but these matts stop heat being lost to the concrete so win win I say).

Used to lay under underfloor heating, levelled with self levelling screed then tiled

Fast delivery. Easier to use boards than insulation on a roll. Finshed job seems to heat up conservatory better than I expected. A little pricey for a bit of polystyrene but hey everything is these days.

Used with under floor heating bought from the same company. Both now under Porcelain tiles. The whole lot went down on to a concrete floor and replaced the laminate previously installed. Under floor heating not yet on but floor already feeling warmer underfoot.The one thing i wish i had never done was put laminate in the kitchen should have gone straight to tile.

They feel like hard polystyrene and dent fairly easily when knelt on, very light weight with not much substance but they have done the job and they do insulate well. We cemented them down with tile adhesive onto a leveled floor and used underfloor heating over then tiled on top. It is impossible not to dent them while on hands and knees laying the heat mats. But easy to cut into shape, our floor looks and feels good.

Giving 4* as it is a bit too soft as i expected. While laying boards, i just kneeled and i made a dent on it.

Good product. Easy to shape. Delivery ahead of estimated time.

Good insulation but very easy to dimple, I would not advise placing under vinyl.
