Over the last few decades, aluminium doors and windows have become a lot more popular. Things have really changed since the days when people thought you could only get aluminium fixtures in just that silvery colour. That’s why for so long they were used in commercial and business applications more than for residential buildings and homes.
However, due to the improvements in coatings, fabrication and manufacturing, they have become slimmer, with greater energy efficiency and available in a huge variety of different colours.
If you are considering aluminium as an alternative to the ever-present uPVC and more traditional wooden sash window, casements or doors, you need to understand the benefits they offer, in addition to better efficiency and versatile colours.
Require Less Maintenance
When compared to uPVC and timber solutions, they require less maintenance in general. They only really need a quick wipe with a damp, clean cloth if they get dirty and inspected to make sure the tracking is free from small stones and grit so the doors or windows can open, shut and function properly.
Incredibly Environmentally Friendly
Aluminium can continually be recycled. It’s interesting to note that around 70% of aluminium that’s ever been produced is still being used today. When aluminium is recycled it uses around 5% of the energy used to create it from scratch. Giving it a relatively small environmental impact.
Strength and Profile
Compared to the likes of timber and uPVC, aluminium is arguably the strongest material, which is why you will see modern aluminium windows and doors with much slimmer and lighter profiles. This is perfect when you need bi-fold or sliding doors and want to let as much natural light in as possible. Aluminium windows can be made to have huge sheets of glass held in the smallest frame of aluminium.
Because of its strength, aluminium windows and doors are resistant to the effects of changes in heat and therefore won’t contact, expand, twist or flex.
While it’s true that a huge part of what gives windows and doors their thermal efficiency is the type of glass and how thick it is, the frame also factors into it as well. In the past, aluminium windows and doors were always considered to be inferior when it came to thermal efficiency, because aluminium is a conductor naturally and not considered an insulator.
Many aluminium bifold, for example, are built with a polyamide thermal break that essentially separates the frame into exterior and interior sections. The thermal break functions like a barrier and greatly reduces the thermal energy flow to and from the aluminium.
Durability and Weatherproofing
When compared to other common materials used, aluminium has a better resistance to the harmful effects of the weather. If looked after and installed properly, aluminium windows and doors could last for around 20 to 30 years, without losing their colour or charm. Unlike uPVC windows and doors, that admittedly have a lifespan of between 15 to 20 years but start looking worn out within as little as 4 to 5.
