If your double glazed sealed unit has misting or condensation in the panes of glass, you might be wondering if they can be repaired. In some cases, it is possible. However, replacement is often the better long-term solution because it restores full insulation and energy efficiency. Read more Can sealed units be repaired.

A U-Value measures how well a window or glazed unit insulates — specifically, how effectively it prevents heat from escaping. It’s expressed in Watts per square metre Kelvin (W/m²K), and the lower the U-Value, the better the insulation performance. For energy efficiency compliance in the UK, new and replacement windows must meet or exceed a U-Value of 1.6 W/m²K. Choosing glazing with a low U-Value helps reduce heat loss, improve indoor comfort, and lower energy bills. If you’re unsure which U-Value is right for your project, our team is happy to advise based on your specific needs.

Well-designed glazing can make a noticeable difference in reducing outdoor noise. One effective method is using double glazed units with glass panes of different thicknesses, which disrupt sound transmission. Incorporating laminated glass in one of the panes also helps absorb and block sound vibrations. For even greater sound insulation, consider specialist acoustic glass options.

The main difference between double glazing and triple glazing is the number of glass panes within the sealed unit — two for double, three for triple. Each option offers its own set of advantages, depending on your home and performance goals. Triple glazing generally offers better insulation, helping retain heat and eliminate cold spots. It can also assist in reducing outside noise, especially when combined with varying pane thicknesses and optimal air gaps. However, it’s important to note that while triple glazing performs better in many areas, it also comes at a higher cost. We recommend discussing your priorities — whether it’s energy efficiency, noise reduction, or budget — with a glazing expert to help you decide which option is the best fit for your home.

Argon gas is a safe, non-toxic, and inert gas commonly used between panes in double or triple glazed windows. It enhances thermal insulation by reducing heat transfer, helping to keep your home warmer in winter and cooler in summer. It also contributes to noise reduction, making interiors more comfortable and quiet. Argon-filled units can remain effective for 20 years or more, but over time, some gas may naturally escape. If you notice condensation or fogging between the glass panes, it could indicate a seal failure and gas leakage. In such cases, the unit can often be repaired or replaced by a professional.
Although argon glazing may cost slightly more upfront, it’s considered a worthwhile investment due to its energy-saving and acoustic benefits. Learn how a Local Discovery Powers Tudor Glass Today.
