Awarded Innovation – recently with the Bavarian State Prize 2022
At the International Crafts Fair in Munich in July 2022, the inventor, master plasterer Stefan Petry, impressed the jury with his special plaster-finishing profiles for windowsills, which enable windowsills to be plastered easily indoors and outdoors.
The profiles decouple the plaster from the windowsill so that it can move freely in the event of thermal expansion, freezing water or mechanical stress without the plaster being damaged or cracking.
The profiles are installed on the right and left of the windowsill exactly where the plaster will later end. In the outdoor area, the precisely fitted profile is sloping so that the water can drain off. In this way, no more water can penetrate into the plaster in the area of the windowsill. This rules out any consequential damage in the area of the plastered reveal.
