Why St Albans Homeowners Are Choosing Secondary Glazing

Since it is installed on the interior side of the building, it generally does not change the outside appearance of the property, making it far easier to get planning approval. Beyond regulatory benefits, there are several engaging reasons to consider this upgrade:
1. Thermal Insulation and Lower Energy Bills
Single-glazed timber windows are infamously bad insulators, enabling important heat to leave outdoors. Secondary glazing creates an airtight thermal barrier by trapping a layer of insulating air between the two panes of glass.
- Decreased Heat Loss: Can lower heat loss through windows by approximately 60%.

4. Condensation Control
Condensation occurs when warm indoor air strikes a cold glass surface area, leading to dampness, peeling paint, and mould growth on lumber frames. Secondary glazing keeps the inner pane of glass warmer, drastically lowering condensation accumulation and securing the fragile woodwork of initial sash windows.
