Quick Step 5mm Thermolevel Underlay (9m2)

Thermolevel is the perfect choice for the installation on top of existing tiles or a highly uneven floor. It also provides extra insulation. Note: it is not compatible with floor heating. To install, in the first underlay row, cut the puzzle edge in order to lay the underlay adjacent to the wall. Then connect the underlay row by row with the puzzle edge. Do this strip by strip, as the laying of your floor progresses. Seal the joints between the underlay by removing the adhesive strip and folding the DPM-flap (Damp Proof Membrane) of the following row. To join strips on the short side, always use a dampproof tape.
