How Aluminum Doors and Windows Enhance the Energy Efficiency of a Building
Buildings that are energy efficient are now seen like a luxury instead of a necessity. Many countries are introducing new laws to improve the energy efficiency of buildings in line with making the world greener.
This has prompted a holistic look into how structures are built. Leading manufacturers are taking this requirement into consideration and are now integrating thermal insulators to aluminum doors and windows so as to comply with regulations on energy efficiency.

Conserving energy is a serious issue. Hence, architects have to consider the energy efficiency of a building since a lot of energy is used in cooling or heating the interior spaces.
A key solution to reducing energy consumption in a home is by cutting down on internal illumination through increasing the number or size of windows to increase the amount of natural light that enters into a space. However, this tends to increase heat gain or loss since most doors and windows tend to be poor insulators.
The energy efficiency of any building, especially the glazing in the building, has always been considered in cold environments due to the obvious high costs of heating the interior spaces.
Today, the costs of keeping an interior space cool are also as important. In cold areas, it is crucial to ensure heat is kept in and cold is kept out. In hot areas, it is important to keep cool air in and hot air out. These measures are vital to reduce energy consumption.
The measurement used in evaluating thermal performance or efficiency of a material is known as U-Value. It is simply a measure of loss of heat through a specific material. In this respect, the lower the U-Value of a building material, the better the material in insulating heat. This means that a material with low U-Value will resist heat loss or gain.
Flow of energy through glazed doors and windows is based on four key factors which are convection, conduction, air leakage, and radiation.
Convection– Air or a fluid tends to move due to heat fluctuations. When hot, air or a fluid becomes less dense and tends to rise. While colder, it becomes denser and tends to sink due to gravity. As a result, there is movement of heat.
Conduction– This is a process through which a material transmits heat directly through it from one side to the other when there’s a difference in temperature.
Air Leakage– This is temperature flow, either out or in, through openings in a poorly sealed material such as a door or window frame. For instance, some windows or doors lack proper seals and this makes them leak both cold or hot air and this means energy inefficiency.
Radiation– This is heat transfer through glass in form of light as an invisible spectra.
Both aluminum and clear glass are known to be poor at insulating heat. These window materials contribute to the energy needed to ensure optimal heat conditions are maintained in a building. Designing aluminum windows that considers all the heat transfer methods is crucial towards improving the energy efficiency of a home to make more savings on energy.
Aluminium– This material is opaque and is usually affected by radiation. It absorbs radiation through absorption and converts it into convectional and conductive heat. It is a good conductor of heat and this is why it is relied on as a reliable heat sink in electronic devices such as computers. It is therefore crucial to control the convection and conductive properties when designing a window or aluminum door.
Glass– This is a transparent material and is not highly affected by radiation, but it allows transfer of heat as infrared radiation, thus heating an interior space. Glass is also poor in insulating heat and has both convection and conductive properties.
Glazing systems contribute a lot towards the cost of a building. Investing in glazing aluminium systems that are thermal efficient will ultimately pay off. When energy costs rise, the energy that is saved through having energy efficient systems will ultimately put the money back into your pocket. Hence, energy efficient systems pay for themselves.
Construction designs for buildings are now changing from less energy efficient systems to more energy efficient systems by using aluminum doors and windows that have effective heat insulators. Quantity surveyors, architects, and other construction professionals are now designing buildings using aluminum doors and windows that fully comply with Australian standards on thermal efficiency.
