The frame is really a quality product. That you pay a little more than the competition is only logical. Compared to competitors' plastic frames, the frames are already more stable and sturdy. The possibility to place the windows in different ventilation positions is really great. The planning of the Knipping company is a bit messy, improvements can be made here. You only hear a few days in advance what the exact start date is and then it is indicated that everything is ready in 2 days. The installation took 3 days and there was some discussion about the finish. When the discussion was held, everything was really neatly finished. The technicians who have placed everything Fred, Nick and Jan are really top professionals who understand their profession.
I would certainly recommend this company to everyone.
