Why Choose Double Glazing?

Double glazing offers a range of important benefits for homeowners by improving comfort, efficiency, and overall living conditions. By using two panes of glass separated by an insulating layer, often filled with argon gas, double glazing significantly reduces heat loss, helping to keep your home warmer in winter and cooler in summer while lowering energy bills. It also helps minimise condensation on internal glass surfaces, improving visibility and supporting a healthier indoor environment. In addition, the insulated gap between the panes reduces external noise, creating a quieter and more relaxing living space. Altogether, double glazing is an effective way to enhance thermal performance, comfort, and everyday practicality throughout your home.

Low-E Glass

High performance, Low-emissivity glass (Low-E) glass is designed to reduce heat loss and is an essential component of energy-rated windows. There are two main types of Low E glass: hard-coat and soft-coat. At KJM, we use soft-coat Low E glass because it offers several advantages over hard-coat alternatives, including better light transmission, improved U-values for enhanced thermal performance, and greater clarity with a more neutral appearance.

Our windows also feature low-iron glass as standard in the external pane. By reducing the iron content in the glass, solar gain is improved, allowing more natural light and warmth into your home. This helps contribute to the excellent performance of KJM’s A rated windows, supporting comfort and energy efficiency throughout the year.

Triple Glazing

When this page was first written, we did not offer 44mm triple-glazed windows and doors. Today, however, our VEKA triple-glazed range can improve thermal performance by over 40% compared to our best-rated double glazing. You can learn more about the benefits of triple glazing on our dedicated blog page about triple-glazed windows.

If your home still has older uPVC windows, they are likely to be far less energy efficient than modern alternatives. Upgrading to today’s A-rated windows can significantly improve insulation, enhance comfort, and provide more secure locking systems. For more guidance, take a look at our free blog post, Replacing Your Old uPVC Windows, available to browse on our site

We understand there are many companies offering double glazing, so we work hard to stand out for the right reasons. Our quotes are completely free and our friendly, non-commissioned sales team provide honest guidance on a wide range of window styles and materials to suit all budgets, while also considering important factors such as your local environment and whether additional sound insulation would benefit your home.

We supply the latest uPVC double glazing systems, including Residence 9 and Beaumont windows that closely replicate the appearance of traditional timber, alongside a full range of hardwood and aluminium windows, doors, and conservatories to enhance both comfort and style. For maximum energy efficiency, our triple glazing offers outstanding insulation, and as secondary glazing specialists, we provide one of the most effective solutions available for reducing outside noise, helping you create a quieter, warmer, and more comfortable home.
