<p>Plastics cladding panels made of e.g. foam material, for insulating the walls of buildings, and used for applying a plaster layer, incorporate a pattern of grooves on both sides. These grooves are dovetail grooves, and large grooves alternate with smaller grooves. In addn. two edges can incorporate sloping sides grooves to interlock with correspondingly shaped tongues on the edges of adjacent panels. Special panels include a sloping edge so that they can be used in pairs for corners of walls.</p> |
