Solar window films are made of a polyester base coated with scratch-resistant material, protecting the glass. They also reflect heat. Under freezing weather conditions, this coating can be applied in the interior of windows, reducing heat loss. The films also offer a higher degree of privacy.

Selecting a tint with higher reflective properties prevents any outsiders from being able to peer inside your home, but still allows those indoors to gaze outside. In case of impact, the films also make sure that the windows stay intact as much as possible.

Finally, solar window films help reduce room heat by reflecting solar heat. In summary, solar window films are an efficient and cheap way to reduce room temperature and your monthly utility costs.

Here are the different kinds of films and their main uses:


Dye Films

As the name would suggest, these films have a layer of a dyed film attached to the interior of the window. You might think that this will cause the room to heat up because the film will absorb heat. However, what really happens is that the temperature is transferred into the glass and carried away by the wind. Moreover, the dark tint is perfect for those looking for some privacy.


Deposited Films

A deposited film is created through a deposition process. In this process, a film is inserted into a tank filled with metal ingots of either nickel-chrome or aluminium. Air is then sucked out of the container, reducing the pressure and creating a vacuum.

After the air is completely sucked out, the empty space is then pumped full of argon gas. Heat is then applied to the tank. The heat causes the metal to release particles that coat the film. This results in a thicker film than most, which limits its applications. However, this thickness makes the film darker and much more reflective.


Sputtered Films

 Instead of going through a deposition process, the film goes into the sputtered process instead. Similar too the deposition process, the sputtering process takes place in a vacuum chamber. A film is placed in a tank, along with the metals, before the air is sucked out. Argon gas then fills the chamber.

This time, instead of heating up the tank like the deposition process, the metal is put through atomic manipulation. During this process, the metal is blasted by charged ions, discharging the metal atoms and releasing them from the metal. These free metal atoms then land evenly on the polyester film’s surface. Sputtered films are superior in blocking UV radiation, but they cannot effectively prevent heat from passing through the glass.


Hybrid Films

As the name suggests, this film is a combination of metal and dyes. Because of this, it benefits from both applications while limiting its disadvantages. The film is slightly less reflective and lighter in colour compared to its metallic counterparts. Still, it maintains the ability to block the heat because of the dyed layer.
