Modern business buildings tend to have a lot of glass. Whether it is because of glass panelling that this so common nowadays, or simply the fact that there are many more windows, these buildings tend to face more issues related to glass than other structures. For instance, too much heat due to sunlight and glare, which translates into escalating energy bills.
There are different types of window films, designed to combat several problems related to glass. When it comes to sun control, there are tinted films that can reduce the intensity of sunlight entering through the window. This not only prevents glares but also keeps the temperature from rising, which results in lower energy consumption. Tinted films are also used in situations where privacy is needed. Offices, clinics and other spaces can benefit from tinted glass films on partitions and other transparent surfaces.
Glass is an inherently fragile material. Toughened glass is available, and is indeed used in many commercial buildings. However, additional security can be ensured by installing a safety film on all windows. These films are typically made of polyester and are fixed directly onto the glass. Even if the glass is shattered, the film holds it in place, preventing anyone or anything from being able to break in through the window.
Window films may also be used for aesthetic purposes in commercial buildings. Fully transparent glass is not always the best option, especially for buildings with a lot of unified glass panelling. In such structures, tinted or matte finish glass can sometimes work better, as it not only looks sleeker but also affords more privacy. A variety of window films are available, in various colours as well as textures. Etched glass films are particularly popular as they provide a far cheaper alternative to actual etched glass.
The main reason why commercial buildings opt for window films is sun control and the resultant energy savings, which practically pay off the cost of installation. Installing tinted window film is a relatively hassle-free process in comparison to replacing or reinstalling windows, and can be very effective. In fact, tinted films are able to block out as much as 80% of the sun's heat. This also slows down fading of the interiors, which will be another long term saving!
Glass reflects sunlight and therefore increases the ambient temperature. As such, glass buildings are not the best choice from the point of view of environmentally friendly structures. A green building is one that makes use of natural resources, such as sunlight and wind, to its advantage. Instead of working against natural forces, it harnesses them and in doing so minimises the energy consumption of the building. However, vast use of glass in buildings has been on trend for many years now, and the trend does not seem to be waning.
