FAQ

What is secondary window glazing?

Secondary window glazing is a method of adding an additional layer of glazing to existing windows.

It involves installing a discreet secondary window pane or unit on the interior side of the existing window to improve thermal efficiency, reduce noise, enhance security, and provide other benefits.

What are the benefits of secondary window glazing?

Secondary window glazing offers several benefits, including:

• Improved thermal insulation, reducing heat loss in the winter and heat gain in the summer.
• Noise reduction, creating a quieter and more peaceful indoor environment.
• Enhanced security by adding an additional barrier against intruders.
• Preservation of the original window aesthetics and architectural character.
• Cost-effective alternative to full window replacement.
• Quick and non-disruptive installation process.

How does secondary window glazing improve energy efficiency?

Secondary glazing adds an extra layer of insulation to your windows, which helps reduce heat transfer and minimise energy loss.

It creates a thermal barrier that can significantly improve the energy efficiency of your home or business, leading to reduced heating and cooling costs.

Will secondary window glazing change the appearance of my windows?

The units are custom-made to fit your existing windows, and various frame options are available to match your décor. Our goal is to preserve the aesthetics of your windows while providing the desired benefits.

Can secondary window glazing reduce noise from outside?

Secondary window glazing is effective in reducing external noise infiltration.

The additional layer of glass and the air gap between the primary and secondary windows act as a buffer, absorbing sound waves and reducing noise levels inside your property. Acoustic glass options can further enhance noise reduction.

Secondary window glazing is often the preferred choice for listed or heritage buildings where the original windows must be preserved.

Customised solutions can be designed to ensure the secondary glazing seamlessly integrates with the existing windows, maintaining the building’s architectural character.
