8 Benefits of Using Aluminum for Windows and Doors in 2023!

It has been said that aluminium is a "magical metal." It is the third most prevalent component in the earth's crust and the most prevalent metal in the world. It is mostly found as bauxite ore. So why is it ideal for curtain walls, doors, and windows?

Modern aluminium alloys have unique chemical, physical, and mechanical qualities that are responsible for the material's significant surge in global utilisation, which is over 5% higher per year.

In this blog, we will discuss 8 benefits of why aluminium doors and windows are driving the market and are expected to continuously grow in the upcoming future!

1. Lightweight 

With a specified weight of about 2.7 g/cm3, aluminium is an extremely light metal that is roughly one-third that of steel or copper. It's one of the lightest metals that are readily accessible on the market. This makes it an ideal choice for door and window panels, but utilising a light-weight frame is crucial for curtain walling. The lighter the better for curtain walls because they are not structural and can only support their own weight.

2. Corrosion-Resistant

Aluminium is your go-to pick if you are seeking a window that requires less maintenance. This is due to the fact that aluminium rapidly develops a protective coating of aluminium oxide upon contact with air. This layer has very high corrosion resistance to anything the weather can throw out, even acid rain, and won't be harmed by cleaning agents. Furthermore, whatever the climate is like, aluminium window frames won't swell, break, split, or warp over time as wood or PVC-U ones will. By covering the surface with paint or anodizing it (often using powder coating), corrosion protection can be further strengthened.

3. Unbreakable Element

In case you forget your GCSE chemistry, aluminium has been both malleable and ductile, which means it can be twisted, pressed into form, or pulled out into a thin wire without reducing the strength or breaking or cracking. It is hence flexible rather than brittle. Aluminum is really the second-most malleable and sixth-most ductile metal. This is great news for anyone who wants a curved wall or window since it makes it possible to bend or press the aluminium frame profiles into the desired form without having to worry about them breaking.

4. 100% Recyclable 

Whenever it comes to recycling metals, aluminium is extraordinary. The grade of recycled aluminium is the same as that of virgin, and it is 100 per cent recyclable. This implies that it can be recycled repeatedly. In fact, today's use stands for close to 75% of all aluminium ever produced. This is fantastic news for the supply of aluminium, especially because the global demand for aluminium has increased to over 29 million tonnes annually since the first industrial amounts of aluminium were supplied almost 100 years ago. The good news for the environment, however, is that recycling and remelting only consumes 5 to 10% of the 14,000 kWh needed to generate 1 tonne of new aluminium. which translates to cheaper expenses and a lesser carbon imprint.

5. A Strong Metal for Windows and Doors

The frames for windows, doors, and curtain walls are made of aluminium alloys. This is due to the low tensile strength of pure aluminium on its own. However, it gains significantly more strength when alloyed with other elements including manganese, silicon, copper, and magnesium. The tensile strength of pure or unprocessed aluminium is about 90 MPa, but when combined with other metals, it may reach over 690 MPa. In reality, when utilised as an alloy, aluminium, which is among the lightest technical metals, has a much greater strength-to-weight ratio than steel.

6. Forms an Alloy Easily

Aluminum is frequently alloyed with certain other elements to enhance its physical qualities.  For instance, by just adding manganese, pure commercial aluminium's strength may be raised by 20%. Along with silicon, copper, zinc, iron, and magnesium, aluminium also forms strong alloys. As a result, a variety of alloys with qualities suited for certain purposes may be created. Aluminium alloys containing silicon and magnesium are a great option for extruded aluminium profiles and are used by aluminium glazing companies. They have great corrosion resistance, and high strength, and are extremely formable, weldable, heat treatable, and versatile.

7. Easily Made Into Panels and Frames

Aluminum window frames or panels are simple to manufacture utilising the extrusion method, which involves pushing the pre-heated aluminium alloy through a die to generate an aluminium profile. The frame or panel then is created by joining these profiles together. The window frame's distinct features are a result of the design of these profiles.

These can have elaborate features, but happily they can be produced using a single extruded segment, making the features sturdy and long-lasting. Moreover, aluminium is well-suited for machining, which makes it simple to precisely manufacture the aluminium features into the completed window frame.

8. Decorative Finish

To give aluminium a decorative smoothness or textured appearance, it may be readily anodized or powder coated. In other words, aluminium windows, doors, and curtain walling not only function well but also look great. By submerging the aluminium in an acidic electrolyte and running an electric current through it, anodizing is achieved. By doing this, an attractive, long-lasting, corrosion-resistant aluminium oxide finish is created on the metal surface. It is incredibly durable because the aluminium oxide is completely bonded with the underlying aluminium and cannot chip or peel. As the aluminium oxide has a pore structure, sealing is necessary to make it corrosion-resistant and also it gives a nice decorative finish to window or door frames and panels.

The Bottom Line,

We have discussed all the benefits of using aluminium doors and windows for your residence or commercial buildings this 2023! It makes sense that more and more people are selecting aluminium windows, doors, and curtain walling for both commercial and residential structures given all of its advantages.
