By creating an additional barrier and an insulating layer of air, secondary glazing reduces heat loss. This can cause a reduction in energy expenses and a more constant internal temperature, getting rid of the “cold spots” frequently found near old windows.
3. Condensation Control
Condensation takes place when warm moist air strikes a cold surface. Expert installers can consist of well balanced ventilation within the secondary frame to permit air to distribute between the panes, substantially lowering the risk of mold and lumber rot on initial frames.
