This is the most economical irreversible option. It involves a single frame that does not open. It is perfect for windows that are utilized strictly for light and where ventilation is not needed. Since there are no moving parts, the maintenance costs are essentially zero.
Horizontal Sliders

Designed particularly to mimic standard lumber sash windows, these are the most aesthetically pleasing option for Victorian or Georgian homes. They make use of spring balances to hold the weight of the glass. Due to the accuracy engineering needed, these sit at the higher end of the rates scale.
Hinged Units
These function like a door, swinging inward. They are often utilized when the main window has an unique opening mechanism or when completely unblocked access to the initial window is needed. They require premium hinges to support the weight of the glass, contributing to a greater price point.
The Benefits: Why the Investment is Justified
While the preliminary expense may appear significant, secondary glazing provides a measurable return on financial investment through several avenues:
Reduction in Energy Bills: Secondary glazing can decrease heat loss through windows by up to 60%. Over time, the savings on heating bills can balance out the setup expenses.Sound Reduction: For residential or commercial properties near busy roadways, airports, or railway, secondary glazing is typically more reliable than standard double glazing for acoustic insulation. It can decrease external noise by up to 80% (approx. 50dB).Condensation Control: By providing an internal seal and eliminating cold spots on the primary glass, secondary glazing considerably lowers the risk of condensation and subsequent mold growth.Preservation of Property Value: In listed structures, changing windows with uPVC double glazing can really reduce residential or commercial property value or result in legal fines.
