2. Improved Thermal Efficiency
By producing an additional barrier and an insulating layer of air, Secondary Glazing Wooden Options glazing decreases heat loss. This can lead to a decrease in energy costs and a more constant internal temperature, eliminating the “cold areas” often found near old windows.
3. Condensation Control
Condensation takes place when warm damp air hits a cold surface. Professional installers can consist of well balanced ventilation within the secondary frame to permit air to distribute in between the panes, significantly lowering the threat of mold and wood rot on initial frames.
