Quality Double Glazing And Triple Glazing That Performs Exceptionally

Triple glazing uses three panes of glass within a window profile, whereas double glazing uses two. This additional layer of glass improves heat retention and soundproofing, helping reduce both heat loss and sound transmission from busy roads or external noise. While modern double glazing offers significant improvements in reducing cold air intrusion and heat retention, the extra pane in triple glazing provides an even lower U-value, meeting and often exceeding UK building regulations.

Double & Triple Glazing Options

We supply and install double and triple glazing from industry specialists Smart Glass and Planitherm. Each type of glazing provides added levels of security, energy efficiency, and soundproofing. Our double glazing reduces heat loss and cold air infiltration, while triple glazing offers an extra layer of glass for further insulation. Both options contribute to a comfortable living space with less heat escaping through windows.

These glazing options come in various styles, including upvc and aluminium frames, with a wide range of colours and spacer bar options to complement any home style. We also offer UV protection coatings, ideal for areas such as conservatories, as well as self-cleaning glass options for ease of maintenance.

Should You Choose Double or Triple Glazing for Your Home?

When deciding between double and triple glazing, consider the following factors:

Energy Efficiency: Double glazing consists of two panes of glass separated by an air or gas-filled cavity, reducing heat loss compared to single glazing. Triple glazing adds an extra pane, further improving insulation. This additional layer can be particularly beneficial in colder climates, as it helps retain more heat inside your home.
Noise Reduction: Triple glazing offers better sound insulation due to the extra pane of glass, making it a suitable choice for homes near busy roads or noisy areas.
Cost Considerations: Triple glazing is generally more expensive than double glazing. The price difference can be significant, so it’s important to weigh the initial investment against potential energy savings and comfort improvements.
Weight and Frame Compatibility: The additional pane in triple glazing increases the thickness and weight of the window unit. Ensure that your window frames can support this extra weight, especially if you’re considering an upgrade from old double glazing.
Condensation Control: Both double and triple glazing help reduce condensation compared to single glazing. However, triple glazing’s superior insulating effect can further minimise condensation on window glass.

While triple glazing offers improved insulation and noise reduction, it comes at a higher cost and may require compatible window frames. Assess your home’s specific needs, climate, and budget to make an informed choice between double and triple glazing.

Double and triple glazing each offer unique benefits suited to different budgets and home environments. To get a bespoke quote tailored to your budget and specific home needs, contact Great Harwood Windows for a free, no-obligation consultation.
