Nowadays, almost everyone is familiar with APU mouldings and they are commonly used in plaster spraying for lining. Over time, different manufacturers of these mouldings have appeared on the market and the main problem is that over time, a crack develops between the apu moulding and the window. The reason for this is that the window moves due to weather conditions and this creates unwanted cracks and this is very disturbing. The solution is to use the APU moulding with cover sleeve No. 37111 from the manufacturer PROTEKTOR. This profile contains a 3 millimetre wide covering cuff and covers the foam adhesive tape that is taped over the window. In the event of movement of the window, it will cover the resulting crack. Another advantage is its sealing function. Builders who did not use sealing tapes on the windows when fitting the window, this APU strip can perform the sealing function.
