Chambers, in appearance

Also, the strength of the number of chambers directly in the window frame will also affect the preservation of heat. In this case, it is about the number of air chambers in the window frame. You yourself understand that the greater the number of air layers between the house and the street, the less heat will leave your home. Accordingly, the more such cameras in the PVC frame, the thicker it is. For example, a frame that consists of three air chambers, in appearance will be very thin. The best option is five air chambers in the frame of the PVC window structure.
