Die APU-Window reveal bead with mesh ROMA W31

The APU window reveal bead with mesh ROMA is used in compound heat insulation systems as specified in the latest APU selection criteria. Within the reveal the profile is stuck at the side onto the existing roller shutter guide rail and after completion of the plastering work forms a clean and reliable termination of the plaster.

The profile comes with a self-adhesive PE foam tape, which ensures a watertight, lasting seal. After the protective flap is pulled off, the integrated TPE loop can absorb movements in the area around the joint. There is a fabric window reveal bead welded onto the profile. Each bar has a fabric overhang on one side of 10cm in the lengthways direction. There is a piece of self-adhesive tape on protective flap in order to secure the third-party protective film. This protects the window during the plastering work. After completion of these tasks, the protective flap is pulled off and what is created is a clean edge to the plaster.
