Diall 2.2mm Extruded polystyrene (XPS) foam Laminate & solid wood flooring Underlay panels

Very brittle and splits along the folds when trying to lay out the underlay. Also it doesn't lay flat, and as it's stiff you can't fold it around architrave for cutting to shape in place, everything has to be measured or marked from a template. I much preferred the grey underlay B&Q used to sell.

Only bought this because I needed a thin underlay, but it needs an extra vapour barrier and is expensive

Bought this underley for doing my laminate floor just too easy to break apart. In a narrow space like my lobby kept tearing at every seam to the point it was very frustrating going to do my living room next will not be getting this stuff for that will definitely be looking for something better. Used to sell similar Gray underlay this was much better.

This one the only underlay in store so he no choice as the job was urgent. It's impossible to lay without tearing. Even after the fight each step you make leaves an imprint if your lucky... most of the time it just tears again. Utter rubbish. Never had a complaint about B&Q products before but this is just the pits. Avoid at all cost!!!

I bought this in January 2017 because i could not find the underlay i used before. I used it in the kitchen and found it ideal. I walked on it whilst laying the laminate boards and it did not flatten under foot. If you keep the main part under control and cut it roughly to size there is no splitting. Great product.
