Secondary Glazing in Uxbridge & West London

Secondary glazing is a slim, discreet inner window fitted to the inside of your existing window frame. It creates a sealed air gap between the panes that delivers impressive improvements to noise reduction and thermal insulation — without touching your original windows.

It's the first choice for properties in conservation areas and listed buildings, where replacing original windows isn't permitted. It's also ideal for Victorian and Edwardian terraces, sash windows, period properties and anywhere that needs significantly better sound insulation — such as homes near busy roads, flight paths or railway lines in Uxbridge and West London.

AMB Glass designs, manufactures and installs bespoke secondary glazing panels tailored to your exact window dimensions and opening type.

Specialist Glazing Products

Made to Measure for Every Window

Secondary glazing is not a standard product. We measure every window individually and manufacture each panel to precise dimensions so it sits flush and operates smoothly, whatever the window shape or size.

Ideal for Listed Buildings & Conservation Areas

Secondary glazing is explicitly permitted in listed buildings and conservation areas because it leaves the original windows completely untouched. We're experienced in working with planning officers and heritage consultants to ensure compliance.

Dramatically Reduces Noise

The wider the air gap between original window and secondary panel, the greater the noise reduction. With a 100mm or larger gap, secondary glazing can reduce noise penetration by up to 80% — a genuine transformation for homes near main roads, the M25/M40, or Heathrow flight paths.

Improves Thermal Insulation Too

As well as noise, secondary glazing significantly reduces heat loss and draughts. Many customers notice the difference immediately — particularly in older sash windows that rattle in the wind.

Secondary Glazing Options

Horizontal Sliding Panels

The most common type. One or two panels slide horizontally within a slim aluminium frame. Clean, minimal and easy to clean — panels can be removed entirely for window cleaning access. Suited to standard rectangular windows of most sizes.

Lift-Out Panels

The simplest and most discreet option. The secondary panel lifts away from the frame for ventilation or cleaning access. Best for windows that are rarely opened or for maximum acoustic performance where a sealed unit is required.

Side-Hung Casements

Secondary panels that hinge open like a door, providing full access to the original window behind. Ideal where the primary window needs to be opened regularly for ventilation.

Top-Hung Fanlights

For windows with a top-opening fanlight section. We match the secondary panel to the primary window's opening pattern so ventilation is maintained.

Bespoke Shapes

Arched windows, Gothic points, angled frames — we manufacture secondary glazing for non-standard shapes. Send us a photo and your dimensions for a quote.

If you have listed status or planning restrictions, secondary glazing is the right solution. If your property has no restrictions and you want the best thermal performance, double glazing may be more appropriate. We're happy to advise — call us for a free survey.

Frequently Asked Questions

What is secondary glazing?

Secondary glazing is a second, independent window fitted on the inside of your existing window. It creates a thermal and acoustic barrier using the air gap between the two panes. Unlike double glazing, it doesn't replace your original windows.

Is secondary glazing as good as double glazing?

For noise reduction, secondary glazing is often superior to double glazing because the air gap is much larger — typically 75–150mm vs 12–16mm. For thermal insulation, modern double glazing has a slight edge, though secondary glazing significantly improves on single glazing.

Can I use secondary glazing in a listed building?

Yes. Secondary glazing is the standard recommended solution for listed buildings because it doesn't alter or remove the original windows, which must be preserved. We have extensive experience working in conservation areas and listed properties across Uxbridge and surrounding areas.

Will secondary glazing work on sash windows?

Absolutely. Sash windows are one of the most common applications. We design the secondary system to allow your original sashes to continue operating — using a lift-out or horizontal sliding panel to maintain access.

Can I open the window if I have secondary glazing?

Yes. We choose an opening system for the secondary panel that matches how you use the original window. Most installations allow full ventilation access.

How is secondary glazing fitted?

A slim aluminium frame is fixed to the internal window reveal (the surrounding wall or frame). The panel or sliding system then sits within this frame. Installation is clean and tidy with minimal disruption.

How much does secondary glazing cost?

Cost depends on the number of windows, their size and the type of opening system chosen. Contact us for a free survey and written quote — there's no obligation.
