With the UK's commitment to the Future Homes Standard and fluctuating energy prices in mind, homeowners in Wiltshire are increasingly looking for ways to future-proof their properties. At NexGen Windows, a multi award-winning local business with over 40 years of experience, we have seen a significant surge in interest regarding one particular upgrade: triple glazing.
While double glazing has been the industry standard for decades, triple glazing is rapidly becoming the go-to specification for those seeking the ultimate in thermal performance and acoustic comfort. Whether you are living in a period property in Marlborough or a modern detached home on an exposed elevation in Swindon ‘Old Town’, understanding the science behind that extra pane of glass is key to making an informed investment.

What makes triple glazing so appealing for modern homes?
The primary appeal of triple glazing lies in its ability to create a near-impenetrable thermal barrier. While a standard double-glazed unit consists of two panes of glass separated by a single gas-filled cavity, triple glazing introduces a third pane of glass and a second cavity.
This configuration fundamentally changes how heat moves through your windows. By creating two separate insulating layers, typically filled with inert argon or krypton gas, triple glazing significantly reduces heat transfer. For homeowners, this translates to a home that stays warmer for longer, requiring less intervention from the central heating system even during the height of a Wiltshire winter.
Beyond the numbers, there is a tangible "comfort factor." We often hear from clients who find that even with the heating on, they feel a chill when sitting near a double-glazed window. These cold spots are caused by the inner pane of glass being significantly cooler than the rest of the room. Because triple glazing offers superior insulation, the internal glass surface stays much closer to the room’s ambient temperature, eliminating that uncomfortable "downdraught" sensation.
When is the higher cost of triple glazing worth it?
It is important to be transparent: there is a higher cost associated with triple glazing compared to double. This is due to the extra materials, the specialised manufacturing process, and the fact that the units are considerably heavier, requiring more robust uPVC window frames and heavy-duty hinges.
However, the question of whether it is "worth it" depends on your specific goals:
However, the question of whether it is "worth it" depends on your specific goals:
- Exposed Locations: If your home is on a hill or an exposed elevation in the Wiltshire countryside, you will feel the benefit of triple glazing much more acutely. The extra insulation protects against the "wind wash" that can strip heat away from double-glazed units.
- North-Facing Rooms: Rooms that receive little to no sunlight stay naturally colder. Installing triple glazing in these areas is a smart move to prevent them from becoming ice boxes in the winter.
- Property Value: A higher Energy Performance Certificate (EPC) rating is a major selling point in 2026. Buyers are increasingly savvy about long-term running costs, and having triple glazing pre-installed can make your property far more attractive.
- Long term benefits: If you’re planning to stay in your property for the long term, it may be more worthwhile investing in triple glazing. If you plan to move in the next few years, then you’ll be less likely to recoup the outlay in terms of reduced fuel bills.
What customisation options are available?
At NexGen Windows, we believe that high performance should never come at the expense of style. Triple glazing is available across a vast range of our products, allowing you to maintain your home’s character while upgrading its efficiency. Our Gallery showcases some of our recent installations to give you an idea of what’s available.
- Frame Styles: Choose from classic casement windows, elegant sash windows, or modern tilt-and-turn designs.
- Colours and Finishes: We offer a wide palette beyond standard white, including woodgrain foils that mimic the look of timber without the maintenance, and contemporary shades like Anthracite Grey or Chartwell Green.
- Aesthetic Details: You can customise your windows with leaded glass, bespoke hardware or even decorative astragal bars to suit a heritage property.
- Integrated Doors: The same triple-glazing technology can be applied to our French doors, patio doors, and bi-folds, ensuring that your large glass areas don't become a source of heat loss. Our team at NexGen takes pride in a "no-pressure" approach. As a multi award-winning business (including Window Supplier of the Year for three consecutive years), our priority is ensuring you get the right solution for your specific home and budget.
NexGen installed Infinity’s windows combine the elegance and style of traditional timber with the modern performance of uPVC.
FAQs
Is triple glazing significantly heavier than double glazing?
Yes, adding an extra pane of glass does increase the overall weight of the unit. Because of this, it is vital to use high-quality uPVC windows with reinforced frames and heavy-duty hardware. At NexGen, we ensure that every frame is engineered to support the additional weight, guaranteeing that your windows and doors operate smoothly for decades without dropping or catching.
Will triple glazing prevent condensation on my windows?
Yes, triple glazing is incredibly effective at preventing internal condensation. Because the internal pane of glass remains much warmer due to the superior insulation, moisture in the air is less likely to condense on the surface. You may, however, occasionally notice external condensation on very cold mornings; this is a sign that your windows are working perfectly, as it proves that almost no heat is escaping from your home to warm up the outer glass.
Can I install triple glazing in an older property?
Absolutely. While many people associate triple glazing with new-build "eco-homes," it is arguably more beneficial in older Wiltshire properties that are harder to heat. We offer a variety of heritage-style frames that allow you to maintain the traditional look of your home while enjoying 2026-standard thermal performance.
Why choose a local expert like NexGen?
Installing triple glazing requires precision. Because the units are heavier and the tolerances are tighter, the quality of the installation is just as important as the quality of the glass.
At NexGen Windows, we are a Certass-certified installer, meaning our work is regularly vetted for compliance with the latest building regulations. We also provide a 10-year comprehensive guarantee on all our installations, backed by the Consumer Protection Association (CPA).
