ABSTRACT:
A spacer for use in connecting the edges of panes of insulating glass, panel walls or the like is coextruded in form of a box-like body together with sealing lips and sealing strips. Its body is preferably composed of a polypropylene filled with glass fibre or mineral powder; its sealing lips of an elastomer and its sealing strips, which effect the adhesion and sealing of the panes or panel walls, preferably of a butyl rubber. The surface portion of its body which is exposed in the application thereof is provided with a vapor sealant such as, for example, a PVDC coating or an adhered metal foil to preclude the occurrence of condensation of water between the panes, wall panels or the like which it serves to space.
