Not All Double-Glazing Is Created Equal

You might be surprised to learn that even if your existing windows and doors are double-glazed, it does not necessarily guarantee they are energy-efficient.

Minimum window energy ratings (WER) didn’t come into effect until 2002, where the minimum WER to meet Building Regulations in England was an E-rating. From 2010 to June 2022, the minimum WER was raised to a C-rating, and even now – following the latest changes in legislation – the minimum requirement is still only a B-rating. To put these energy ratings into perspective, a C-rated window loses up to 94% less heat than an E-rated window.

To this day, many double-glazing companies only install windows and doors that meet minimum Building Regulation requirements. This tends to keep the initial upfront cost to you (the purchase price) down, but having windows and doors with lower energy ratings ultimately means keeping your heating on for longer and spending more on energy bills – not to mention producing more CO2.

Frequently Asked Double-Glazing Questions

There are a few different answers to this question, and it is vital to pay attention to which surface of the glass condensation forms on, as it’s location indicates the cause and points to the solution.

If you’re noticing condensation forming within the two panes of glass in your double-glazed unit (known as the cavity), then this is a visual indication that the seal has failed and the double-glazed unit will need to be replaced.

If you’re seeing condensation form on the room side surface of your glass, this would indicate high levels of moisture and inadequate ventilation in the room. There are different steps you can take to resolve this depending on the type of room (i.e. bathroom, kitchen, bedroom, etc.) and exact cause, but increasing ventilation is always helpful.

If you’ve recently had your windows or doors replaced and are now getting condensation on the external/outside surface of some of them (often described as a light misting or dew concentrated centrally on the glass) after a cold clear night, this is an indication that your windows and doors are incredibly energy-efficient and preventing heat loss from your home. This condensation is temporary, will clear fairly quickly, and won’t lead to any damp problems, so is nothing to be concerned about.

For a deep dive into how and why condensation occurs on certain surfaces, as well as some advice about reducing condensation based on where it’s occurring, please click here.

The lifespan of double-glazing can vary depending on several factors, including its composition, the quality of the installation, and how well looked after and maintained it is.

There are a few different signs that indicate it might be time to consider replacing your double-glazing:

Condensation within the cavity:

If you notice condensation forming between the glass panes, it indicates that the seal has failed and moisture is entering the space between the glass. This not only impairs the thermal efficiency but also affects the appearance of the glass due to the misting and clouding that occurs.

Damage or deterioration:

Physical damage, such as cracks, chips, or warping, can significantly impact the performance and appearance of double-glazing. If the damage is beyond repair or if you notice significant deterioration, replacement may be necessary.

Draughts or air leaks:

Over time, the seals around the windows can deteriorate, leading to draughts and air leaks. If you feel noticeable draughts coming through your windows or doors, especially when they are closed, it might be time to consider replacement.

Energy efficiency concerns:

Older double-glazed windows and doors don’t provide the same level of energy efficiency as newer models with their advances in technology. If you begin to notice a significant increase in your energy bills (that isn’t simply due to energy company price increases) or if your windows and doors are not effectively insulating your home, upgrading to more energy-efficient windows and doors can help reduce energy costs.

Noise reduction:

If you live in a noisy area and your current windows are not effectively reducing the outside noise, upgrading to windows with enhanced sound insulation properties can make a noticeable difference.

But it’s important to note that these are general guidelines. If you have concerns about the performance or appearance of your windows and doors, please do get in touch with your nearest truhouse. team today, and our friendly experts can assess your situation and provide tailored advice.

Unfortunately we don’t currently offer a standalone glass replacement service – we only replace windows and doors in their entirety.
