Expansion joint profile DUO-TEXCorner and fine plaster with 2 x 12.5 cm mesh

Die APU-Expansion joint profile DUO-TEX, for corners W51

The APU expansion joint profile DUO-TEX is used in compound heat insulation systems at building joints. For the flush formation of a clean plaster edge, the profiles for surface areas (W52) and for inner corners (W51) are made.

The profile is made up of 2 plastic profiles, to each of which a strip of mesh is welded. Each bar has a fabric overhang on one side of 10cm in the lengthways direction. Between the profiles there is a mesh-reinforced connecting lug made of soft PVC for absorbing movements. On every bar the connecting lug has a projection of c. 5 cm, so that the profiles are worked on in the area where the pieces abut in overlapping fashion and it is ensured that water gets guided away. The profiles can be connected flush with each other using the plug connectors (Z13) provided. What is created after completion of the plastering work is a clean termination of the plaster. In order to visually cover up the expansion joints, the cover profiles (Z22-F for flat surfaces and Z22-E for corners) are used. These can be painted over using acrylic paints.
