This is the answer to the question What is a pilaster strip to reinforce a window? Who has experience installing it?
Revision 1
It will probably be a multi-part balcony door, where the leaf is 106 x 212 cm. This type of balcony door is often made with insufficient reinforcement for cost reasons. The result is that the entire element wobbles when closing. The applied pilaster strip in the vertical direction is supposed to strengthen the statics and reduce the wobbling. What does this have to do with the permanent grinding of the sash on the frame? Nothing or not much.
As a rule, the construction has between 4 and 12 mm of rebate clearance between the frame and the sash. In addition, the door hardware can still bring the door leaf up by about 2 mm. In addition, a sash lifter should prevent the sash from sinking. Much more can not be said from a distance, without further detailed knowledge in your case.
