Aluminium which is found an ore of Bauxite is one of the most common elements in the earth’s crust. It is widely used while making windows and doors. What are the features that make it popular among windows and doors in Toronto?
It is found that every year, its global percentage of use increases by 5%. This could be because of aluminum’s physical, chemical and mechanical properties. Discussed below are some of the reasons why aluminum is preferred by windows and doors companies.
- Decorative – Aluminium can be powder coated to give a super smooth finish. Thus, doors, windows, and curtain walling made with aluminum-look good. An electrochemical process called anodizing is carried out. Aluminum is immersed in an acid electrolyte bath and an electric current is passed through it. This way, the metal surface gets converted into a durable, corrosion-resistant surface with an aluminum oxide finish. Aluminum oxide is porous and thus needs to be sealed with a special dye or paint, to avoid corrosion.
- Can easily be molded into frames – The process of making aluminum window frames is called extrusion. Here an alloy of pre-heated aluminum is forcefully molded into an aluminum profile. Using this process, even complex designs and intricate patterns can be achieved. The good machinability of aluminum allows its profiles to be correctly fabricated into a finished window frame.
- Completely recyclable – Aluminium is a metal that is 100% recyclable. The quality of virgin aluminum and that of recycled aluminum is almost similar too. Sustainable solutions in any industry are always attractive. Recyclability comes handy here because the demand for aluminum is only going to rise further. Also, it takes approximately 14,000 kWh to produce a tonne of fresh aluminum. However, recycling the same amount takes only about 5% -10% of this. So, higher demands can be met with lower costs and a lesser carbon footprint too.
- Resists corrosion – An aluminum window is easy to maintain. Timber or PVC frames usually swell, crack or split up with prolonged exposure to water or air. With aluminum, this can be avoided. When it comes in contact with air, it produces a layer of aluminum oxide, which is corrosion-resistant. Aluminum frames are also not harmed by cleaning solutions. To keep the frames more protected against corrosion, they can be anodized, or powder coated. This is one of the main reasons why aluminum is used by many companies that make windows and doors in Toronto.
- Lightweight – The weight of aluminum of 2.7 g/cm3. It is very light when compared to steel or copper. Curtain walls can carry only their weight thus a light-weight metal would be ideal. It is also preferred to have light-weight frames for doors and windows.
- Will not break easily – Aluminium possesses good malleability and ductility. It can be pressed into thin sheets or drawn into thin wires without breaking or losing its toughness. Therefore, it can be used to make fancy curved curtain walls and frames as well, without worrying about breaking the frame.
