Warmer, quieter, cheaper to run.
Double glazing works by trapping an insulating layer of gas between two panes of glass, with a low-emissivity coating that reflects warmth back into the room. The result is a home that holds its heat, shrugs off outside noise and costs less to keep warm – which is why A-rated double glazing comes as standard on every window we fit.

The insulating cavity keeps heat in, so your rooms stay warmer and your heating works less.

Common questions about double glazing
Thinking about double glazing? Here are quick answers about warmth, noise, cost and installation across Scotland.
What is double glazing?
Double glazing is two panes of glass with an insulating, gas-filled gap between them. It’s the standard for modern, energy-efficient windows.
Is double glazing energy efficient?
Yes. Our double glazing is A-rated – the insulating cavity and low-E coating keep heat in, helping your home stay warmer and your heating work less.
Does double glazing reduce noise?
Yes. Two panes and a sealed cavity help shut out outside noise, and acoustic glass is available for busy or roadside locations.
Double or triple glazing - which do I need?
Double glazing suits most homes. Triple glazing adds extra insulation and noise reduction and is worth considering for exposed or roadside properties. We’ll advise on the right choice at your free survey.
Will double glazing stop condensation?
It significantly reduces internal condensation – a warmer inner pane and warm-edge spacers cut the misting and damp you often see on single glazing.
Is double glazing secure?
Yes. It’s much tougher than single glazing, with toughened and laminated glass options for added security.
Do all your windows come with double glazing?
Yes. A-rated double glazing is fitted as standard on every window we supply, across all styles and in both uPVC and aluminium.
How much does double glazing cost?
It depends on the number of windows, the style and any glass upgrades. The best way to get an accurate price is a free, no-obligation survey – we’ll give you a fixed written quote with no hidden extras.
