Are uPVC or Aluminium windows better for me?


There are a number of benefits for both uPVC and Aluminium windows. As we think both are great choices, we have put together some pros and cons for you to get an idea of what is right for you and your home.


All windows and doors fitted by Salop Glass have an excellent life expectancy. However, there will be a difference between the lifespan of uPVC vs Aluminium.
uPVC windows on average have a life expectancy of 30 years. However, this will be greatly impacted by the conditions that they face. If they are fairly sheltered from bad weather, they will have a far longer lifespan than those on the seafront.
Aluminium windows have a much longer lifespan of 45 years. This material is not as susceptible to the elements as uPVC and therefore will not show weather-related marks. Aluminium also does not rust, meaning you won’t find any unsightly rust patches.


Where the lifespan may have you already favouring the Aluminium windows, efficiency must also be taken into consideration.
Aluminium windows have always been known for being temperature conductors, meaning that in the winter the cold has access to your home, and the summer heats up the room. However, recent changes in technology have helped to improve this issue, meaning that they can now boast up to an A++ rating in most circumstances.
uPVC has always been known and favoured for its energy efficiency. And with the introduction of triple glazing, this will only increase the efficiency. uPVC also boasts up to an A++ rating.


Both uPVC and aluminium have an excellent security reputation. However, the frames themselves cannot be held solely responsible for security. They will also need to be paired with secure and efficient locks.
Both types of frame will begin to lose their strength as they come towards the end of their lifespan, so if security is a concern for you, you may need to reinvest.

Visual appeal

Previously Aluminium windows have been seen as outdated and boring metal, while uPVC has been known to be basic white frames.
However, modern fashions and choices have now changed these views. Aluminium windows are now considered to be sleek and elegant with minimalist lines. They are also a firm favourite with those who like large open view windows, as the strength of the aluminium allows them to hold larger panes of glass.
Modern advancements in uPVC mean that they are no longer only available in plain white, they are now available in multiple styles and colours. Allowing you to customise them to suit the look of your home.
