and the stabilising layer underneath. This reduces costs significantly. DIN EN 13 489 specifies a minimum wear layer thickness of 2.5 mm.1 Contrary to solid wood parquets, which are always ground and surface-treated after laying, multil layer parquets are already finished at the factory, making the otherwise necessary initial surface grinding process unnecessary. Although engineered parquets can in principle also be renovated by grinding and surface treatment, the number of times this can be carried out is normally less than for solid wood parquets because of the relatively thin top layer. The elements are given a tongue-and-groove finish all around and glued to each other in the groove. Some glueless click systems 2 1 also exist, which save a lot of installation time. Installation is either floating on a full-face, cushioning intermediate layer or by full-face adhesion to the substrate. An adequately large perimeter joint has to be included to allow free expansion of the glued flooring at the edges when this is laid floating. This is covered by a skirting board.

Wood paving Wood paving is composed of small cuboid wooden blocks with edge dimensions similar to stone paving (Fig. 54 and 56, p. 94). The basic elements with their precisely worked sides are pressed together during the laying process, creating an altogether (planned at least) jointless flooring surface. As opposed to other wood floors, the grain of the elements is not parallel but perpendicular to the floor surface, i.e. vertical. The fact that wood is a pronounced anisotropic (direction-dependent) material (see “Deform ation”, p. 94f.) has far-reaching consequences both for the mechanical and deformation behaviour of this type of flooring. From a mechanical point of view,
