The pleats are preinstalled to mount regarding the tension and easily. To the extent this may be true for pinched pleats, they are unremarkable. The pleats can be moved easily and remain even after repeated operation in a horizontal position. This is in stark contrast to the first purchased at the hardware store. My wife and I had first considered to have prepared pleats for installation in the glazing bead measure justice. Since 1st we had no experience with pleats, this would be considerably more expensive and 3. 2. come we did not know whether we really liked pleats in the long run, we have gradually almost all windows fitted relatively inexpensive with pleats from this product range, to gain an impression. Due to the quality and appearance, we then became friends very well with this temporary and it will remain for the foreseeable future too.
Since there are similar pleats even from the same manufacturer in different quality, I would point out that this is about the range 75 ... goes, in this case 75.075.130.01.
