Abstract (en)
A synthetic plate material comprises at least two substantially parallel synthetic-resin plates (2, 3) which are kept at a substantially constant distance from one another by means of strip-shaped spacers (4). The two plates (2, 3) and the spacers (4) together enclose a plurality of parallel, elongate cavity channels (5). The cavity channels (5) are sealed at their ends so that they are dustproof but transmit water and water vapour. This seal (6), according to the invention, comprises a foamed material with an open pore structure which is dustproof but allows of a certain degree of ventilation, so that water and water vapour can pass through it. A device for sealing up the ends of a cavity plate comprises a frame (10) with a practically flat base (12) provided with guiding means (13) for guiding the device along the cavity plate (1). The device further comprises a nozzle (14) for injecting a viscous foam substance into the ends of the cavity plate (1) and driving means (19) for conducting the device along the cavity plate (1) at a substantially constant speed. <IMAGE>
