2. Improved Thermal Efficiency
By producing an extra barrier and an insulating layer of air, secondary glazing reduces heat loss. This can cause a reduction in energy bills and a more constant internal temperature level, getting rid of the "cold areas" frequently discovered near old windows.
3. Condensation Control
Condensation takes place when warm damp air hits a cold surface. Expert installers can consist of well balanced ventilation within the secondary frame to permit air to circulate between the panes, considerably reducing the threat of mold and wood rot on original frames.
