Aluminium and Glass in construction

Aluminum is the third most abundant metal in the Earth’s crust, and the third most abundant element overall. Aluminum is popular because it is lightweight, strong, resistant to corrosion and durable. It is also ductile, malleable, and conductive and has no odour.

Buildings made with aluminum are virtually maintenance free due to aluminum’s resistance to corrosion. Aluminum is also thermally efficient, which keeps buildings warm in cold seasons and cool in hot seasons. Add the fact that aluminum has a pleasing finish and can be curved, cut and welded to any desired shape, it allows modern architects unlimited freedom to create buildings that would be impossible to make from wood, plastic, or steel.

The first building in which aluminum was widely used was the Empire State Building in New York, built in 1931. Today, aluminum is regularly used in the construction of high-rise buildings and bridges. The lighter weight of aluminum makes it easier, faster and more convenient to work with. It also helps reduce other costs. A building constructed of steel would require much deeper foundations due to the added weight, which would drive up construction costs.

Aluminium is widely used together with glass in modern construction projects especially on doors, windows, partitions and curtain walls. The combination results in an aesthetically appealing final product.


Glass has been a fascinating material to humankind since it was first made in about 500 BC. At first thought to possess magical properties, glass has come a long way. It is one of the most versatile and oldest materials in the building industry.

Types of Glass

Float Glass: Float glass is also called soda lime glass or clear glass. This is produced by annealing the molten glass and is clear and flat. Its modulus of rupture is 5000-6000 psi. It is available in standard thickness ranging from 2mm to 20mm. and has weight range in 6-26kg/m2. It has too much transparency and can cause glare. It is used in making canopies, shop fronts, glass blocks, railing partitions, etc.

Tinted Glass: Certain additions to the glass batch mix can add color to the clear glass without compromising its strength. Iron oxide is added to give glass a green tint; sulfur in different concentrations can make the glass yellow, red or black. Copper sulphate can turn it blue, etc.

Toughened Glass: This type of glass is tempered, may have distortions and low visibility but it breaks into small dice-like pieces at modulus of rupture of 3600 psi. Hence it is used in making fire resistant doors etc. They are available in same weight and thickness range as float glass.

Laminated Glass: This type of glass is made by sandwiching glass panels within a protective layer. It is heavier than normal glass and may cause optical distortions as well. It is tough and protects from UV radiation (99%) and insulates sound by 50%. Used in glass facades, aquariums, bridges, staircases, floor slabs, etc.

Shatterproof glass: By adding a polyvinyl butyral layer, shatter proof glass is made. This type of glass does not from sharp edged pieces even when broken. Used in skylight, window, flooring, etc

Extra clean glass: This type of glass is hydrophilic i.e. The water moves over them without leaving any marks and photocatylitic i.e. they are covered with Nanoparticles that attack and break dirt making it easier to clean and maintain.

Double Glazed Units: These are made by providing air gap between two glass panes in order to reduce the heat loss and gain. Normal glass can cause immense amount of heat gain and upto 30%of loss of heat of air conditioning energy. Green, energy efficient glass can reduce this impact.

Chromatic glass: This type of glass can control daylight and transparency effectively. These glass are available in three forms- photochromatic (light sensitive lamination on glass), thermochromatic (heat sensitive lamination on glass) and electrochromatic (light sensitive glass the transparency of which can be controlled by electricity switch.) It can be used in meeting rooms and ICUs.

Glass wool: Glass wool is a thermal insulation that consists of intertwined and flexible glass fibers, which causes it to “package” air, and consequently make good insulating materials. Glass wool can be used as filler or insulators in buildings, also for soundproofing.

Glass blocks: Hollow glass wall blocks are manufactured as two separate halves and, while the glass is still molten, the two pieces are pressed together and annealed. The resulting glass blocks will have a partial vacuum at the hollow center. Glass bricks provide visual obscuration while admitting light

Choosing the Right Glass

Accounting for up to 90% of the thermal performance of windows and doors, glass is the most influential factor in determining window and door energy efficiency. Not all glass products are created equal and it’s vital to select the appropriate glass for specific purpose.

Glass is more than a building material; it offers endless aesthetic and practical benefits.

  1. It’s a great source of knowledge; I think it will be helpful for lot of people who are looking for learning more about the aluminium and glass in construction. Thank you very much for sharing this article.

  2. Am a distributor of Trellidor aluminium shutters in Uganda. Calling for connection to market

  3. A curtain wall system is thin and lightweight, usually aluminum and glass. These walls are not structural, and by design, they are only able to carry their own weight, while transferring the load of wind and gravity to the structure of the building. The design makes it air and water resistant, to ensure that the interior of the building remains airtight.
