XPS Boards Floor Underlay Thermal Insulation Underfloor Heating 600 x 600mm x 6mm Sheets - 1.86m2 to 18.60m2

- Specially built for under floor heating- easy to cut for different sizes- package arrived much sooner than expected so that we could start the work!only downside is that they were slighly different sizes.Overall quite pleased.

....but the sizing wasn't exactly the same on all boards. We used them under 9mm ply so the gaps got covered up but would have been nice to have them all uniform.I would recommend though - it's not as if you see them after the work is done...
