ABSTRACT:
A plastic sheet is disclosed which is used as a subcarrier for insulating linings of building surfaces. The sheet is formed by parallel, alternating, dovetail-shaped channels and grooves. A coarse-meshed lattice matting, having filaments, is glued or partially fused to the backside of the plastic sheet and serves to anchor the sheet to the underlying foundation. This lattice matting stretches over the entire backside or inner surface of the sheet. The webs of the plastic sheet are expandable and can compensate for stresses occurring between the underlying foundation and the external facing material such as ceramic tile.
