uPVC window production capacity is determined by the welding machine. With a double head welding machine, one can produce 1 square (frame or shutter) in 6 minutes. A 2 track 2 shutter window as the name suggests has 1 frame (square) and 2 shutters (2 squares). One would need 18 minutes to make a window. In 8 hours one can do 32 windows.
