How are High Quality Windows Made?

I always wondered what set apart one window from another, but I have never see how any windows are made let alone high quality windows. This is a very short video showing the steps and what goes into a highly automated process of making windows. Big thanks to SIGA for setting up this tour and Haupt for letting us in to check how high quality winows are made in Switzerland RR Building Post Frame Plans RR Merch RR Hats
