Double Glazing: Is It All the Same

So, you’ve decided to install double glazing to your property. However, the next question that comes to mind is whether all double glazing is the same and how to pick the right one.

Differences Between Different Double Glazing


There is a huge difference between different double glazing when it comes to its lifespan. The longevity of double glazing depends on the quality of materials used. Hence, some double glazing might last up to 30 years while other might fail after 5 years. Likewise, if the window frame is made of uPVC, it is likely it will be more susceptible to ultraviolet degradation. Moreover, the installing process plays a major role in the durability of your double glazing. For instance, if not installed properly, the double glazing will have a much shorter lifespan.

Energy Efficiency

You probably know that double glazing is an extremely energy efficient method. However, if of poor quality and failed to be installed properly, it won’t be so energy efficient as expected. In fact, it can be a difference of over £500 a year when it comes to finances.


As a key feature of double glazing, security can differ between different double glazing. It’s extremely important to install double glazing which is resistant to forced entry. Hence, installing proper and good quality double glazing will prevent any unwanted person from entering your home. On the other hand, some double glazing might not offer any resistance at all.
