At Commerce Windows, we understand that choosing the right glazing for your home is an important decision. Not only for aesthetics, but also for comfort, energy efficiency, and long-term savings. Whether you’re in Northampton, Rushden, Kettering, or any surrounding area, our expert team is here to guide you through the differences between double glazing and triple glazing to help you make the right choice for your property.
Understanding Double Glazing and Triple Glazing
Double glazing involves two panes of glass separated by a layer of air or inert gas, such as argon, which acts as insulation. Triple glazing adds a third pane, creating two insulating layers of gas to enhance thermal efficiency. Both types are now commonly installed in modern uPVC windows, including popular styles like flush uPVC windows or coloured uPVC windows in trendy shades such as grey uPVC windows or black uPVC windows.
Double glazed windows have been the industry standard for years, providing solid protection against drafts and noise pollution. Meanwhile, triple glazed windows deliver even higher insulation, making them ideal for properties in colder climates or those with higher energy efficiency requirements.
If you’re considering double glazing replacement or a new installation, it’s important to weigh the benefits of each option. Our experienced double glazing installers in Northampton and surrounding towns are ready to advise you on what’s best. Discover the advantages of both and get in touch with us at Commerce Windows to explore your options.

Thermal Efficiency and Energy Savings
One of the biggest reasons homeowners consider triple glazing over double glazing is energy efficiency. Triple glazing’s extra pane and insulating layers can significantly reduce heat loss, helping keep your home warmer in winter and cooler in summer. This can translate to notable savings on your energy bills, especially in larger homes or drafty older properties.
However, double glazing remains an effective barrier against heat loss, especially if your current windows are single-glazed or in poor condition. Modern uPVC windows fitted with high-quality double glazed windows can still achieve excellent thermal performance, especially when combined with proper sealing and installation techniques.
If you’re in areas like Wellingborough, Corby, or Daventry where winters can be chilly, triple glazed windows may offer that additional thermal protection you’re looking for. But for many homeowners in Towcester or Northampton, investing in double glazing replacement might be a more cost-effective way to improve comfort.
If reducing your carbon footprint and energy bills is a priority, ask our double glazing installers about the latest energy ratings and how these compare between double and triple glazed units. Want to enhance your home’s efficiency? Get a quote from Commerce Windows today.

Noise Reduction and Comfort
Beyond keeping the cold out, both double and triple glazing can significantly reduce noise from busy roads, neighbours, or nearby train lines. Triple glazing does provide an extra layer of sound insulation, so if peace and quiet are a top priority, it’s worth considering.
However, modern double glazed windows with thicker glass panes and gas fills can also deliver impressive noise reduction. The choice often depends on the specific windows and glazing units chosen, as well as the quality of installation. Our double glazing installers ensure every job is completed to the highest standard, reducing the risk of draughts or condensation inside double glazing, which can compromise comfort.
