Product Properties / Benefits:
Flexible, stabilising and isolating underlay sheet with cross-
shaped latex-foam studs on the underside. The studs pro-
vide an air-layer of approx. 1 mm thickness between the
stabilising underlay and the substrate – the underlay serves
as the surface for the new, bonded covering. It has an in-herent, stabilising stiffness for good load distribution and
