Blocking Solar Heat Gain

Probably the most significant benefit of window films is their ability to block solar heat gain. High-quality window films can block a large percentage of the sun’s infrared rays that contribute to heat build-up inside a room. In the Australian climate where the sun can be scorching, films can keep rising room heat at bay when the sun is at its peak, especially during the high-temperature daylight hours of summer. Because on the most extreme summer days, indoor temperatures can quickly rise to dangerous levels, the reduction of heat entering a room through windows is extremely important in maintaining more reasonable room temperatures. As a result, air conditioners can work more efficiently as they are not required to work as hard to cool down the room.

Window Films: reflective vs non-reflective

Window films are made in different types with reflective and non-reflective being two extremes. Reflective films can reflect most of the heat as they contain metal particles which reflect the sunlight. This kind of film is very good for cold and sunny areas where the sunlight penetrates the windows. Non-reflective films, on the other hand, absorb most of the solar energy. Different home or building requirements can guide one in choosing either of the two films. If the goal is to reduce energy consumption during the summer days, a reflective film would be installed to reduce the amount of heat that penetrates the windows.

Glare Reduction and UV Protection

Another important function of window films is to reduce glare, making it easier on the eyes to use screens and work or relax without the glare of direct sunlight, while blocking up to 99 per cent of UV light, shielding the skin and eyes, and significantly reducing the fading of furniture, curtains and carpets. The extra layer of UV protection is yet another advantage to a safer and more comfortable indoor environment.

Energy Savings and Cost Effectiveness

Improving the efficiency of an air conditioning system can result in significant energy savings. As the load on the air conditioner is lowered by the window film, the energy usage drops, resulting in lower electricity bills. This savings over the lifetime of the window film will recoup the initial expense in installing it. In situations where cooling costs can represent as much as half of your home expenditure, coating windows with these films is a low-cost way to increase energy efficiency.

Sustainability Impact

From an eco-friendly viewpoint, this has a great impact because it helps to reduce the demand for air conditioning which in turn reduces the amount of energy used in heating or cooling your home. This will lower the production of carbon emissions into the environment which will help and support our environment goals and sustainability efforts.

Installation and Lifespan

Window films should come with an installation guarantee because for the maximum energy efficiency benefits, professional installation is required. Proper installation will get you the most energy efficiency benefits but improper installation will leave you with bubbles, peeling or an uneven texture, not only does it look bad but it also can degrade performance. Properly installed, window films can be virtually the same energy efficiency benefits over the life of the film.


Before choosing window films for your property, you must consider your specific need, such as the type of windows, the window treatments already in place, your local climate conditions and your budget. Professional advice can be taken regarding the best samples of films to be used based on your need, such as the tint colour, the thickness and even the material properties.


As shown in this article, window films can be a good solution to make air conditioning system more effective by reducing heat gain, blocking UV radiation, cutting glare and saving energy in Australia's climate. It is said that window films provide various benefits in the aspects of saving energy and protecting environment. So I would recommend anyone who wants to improve the energy-saving performance of their home or office to install the window films. Moreover, as environmental concerns grow, Australia will keep on pursuing sustainable lifestyle. The application of window films is a key part of the green building.
