Window reveal bead with mesh PUR-EX-proWith shadow gap and 12.5 cm mesh, grey

Die APU-Window reveal bead with mesh PUR-EX-pro, grey W29-pro

The APU window reveal bead with mesh PUR-EX-pro is used in compound heat insulation systems as specified in the latest APU selection criteria. Within the reveal the profile is stuck flush to the structural element there and thus forms a clean and reliable termination of the plaster with shadow gap.

The profile comes with a self-adhesive PE foam tape, which ensures a watertight, lasting seal. The PE foam tape is covered and protected by the profile contour. The integrated expanding PUR sealing strip is able to absorb relatively large movements in the area around the joint. This is activated by removing the protective flap. 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.
