Joint flank profileWith straight edge and 12.5 cm mesh

Die APU-Joint flank profile W81

The APU joint flank profile is used in compound heat insulation systems for flush plaster joints with existing structural components such as door and window elements and frames. It is put directly on top of the insulation at a distance from the structural element. The watertight seal (e.g., with a PUR sealing strip) is not included and must be done in ac- cordance with the respective manufacturer’s specifications on planning and dimensions. After completion of the plastering work the profile forms a flush, clean termination of the plaster.

The profile has a welded fabric strip. Each bar has a fabric overhang on one side of 10cm in the lengthways direction. The rear mounting limb is available in 2 different overhang lengths:
W81-30 APU joint flank profile, 30mm limb width
W81-60 APU joint flank profile, 60mm limb width

The included plug connectors (Z14) connect the profiles as a flush joint in the area where the pieces abut. The corner is formed using prefabricated corner pieces (Z81-30 or Z81- 60). These are not included in the scope of delivery.
