Once you have decided to upgrade to double-glazed windows, your decision-making is not quite yet over. You’ll also need to think about tint, hinges, energy considerations and more. But one of the most important decisions you’ll need to make is deciding what material you want your window frame to be made of. Several options are available to you, but in this article, we’ll look at UPVC double glazing and aluminium double glazing window frames. We’ll define the two materials and compare them to get a good idea of the pros and cons of each. And if you are struggling to decide between uPVC and aluminium frames for your double-glazed windows, hopefully this blog can help.
Defining Aluminium
Aluminium is a very recognisable silver-grey metal, is a very popular material used in construction, and is praised for its durability. It is probably the most common choice of window frame material for double-glazed windows, but many people do not realise its potential drawbacks, including lack of energy efficiency.
Defining uPVC
uPVC is a relatively new material that is slowly growing in popularity thanks to its energy-efficient benefits and affordability. It is a very strong plastic material that is used to make double-glazed window frames and door frames. It has become incredibly popular in the UK and Europe over recent years.
Comparing Aluminium And UPVC
| Aluminium | uPVC | |
| Insulation | Not great when it comes to insulation as the lack of airtightness lets cool breezes in during winter. Heat is trapped in the metal during summer. | uPVC window frames provides both sound insulation and thermal insulation, keeping your home at a comfortable temperature. |
| Durability | Aluminium windows can last a very long time, but they need to be coated properly to avoid corrosion. | It can last more than 20 years if the right maintenance steps are taken. Very stable material. |
| Maintenance | Cleaning and coating your window frame is essential. Wiping away condensation is also necessary to avoid moisture build-up. | Very little maintenance is required as there is no risk of rust or corrosion. It can be washed with soapy water. |
| Affordability | Aluminium is expensive to buy. | The biggest advantage to uPVC is its affordability. |
