Local Window Fitters

Have you got a specific idea in mind for how you would like your double glazing to look? At GHI, we have a cast range of customisation you can choose from to help you make your new double glazed windows or double glazed doors personal to you and your Carshalton property. Before we talk about what advantages double glazing offers, it’s important to understand exactly what it is as this helps to explain what it does. Put simply, double glazed windows feature two layers of glass with a layer of gas sealed in the gap between them.

You’ll also have peace of mind from knowing the company has undergone thorough vetting. Once the company finishes your double glazing installation, it should provide a FENSA certificate. Check if local installers have photos of their completed projects available for prospective customers to look at. Local companies may even be able to tell you which houses they’ve worked on in your neighbourhood, allowing you to see the quality of the windows and installation for yourself.

With two spaces, or airlocks, the energy efficiency is increased by as much as 50%; however, triple glazed windows are around 20% more expensive than double. The manufacturing process for double glazed windows is quite straightforward; each unit is created by cutting two panes of glass according to set measurements. Then, the spacer bars are manufactured to size by double glazing companies to ensure that they separate the two panes to reduce heat transfer and improve thermal insulation.
