Exploring window films – what makes liquid crystal film superior?
Window films are utilised in building interiors mainly to enhance comfort and spatial functionality. They can reduce the penetration of light and solar radiation, prevent scratching or breaking of windows, and protect the privacy of those inside the building. Additionally, decorative window films are available, designed specifically to decrease visibility while simultaneously enhancing the aesthetic appeal of the windows. Many films integrate a variety of features to achieve the desired outcome. So, what are the types of window films? Is there a film on the market that stands out significantly from the others?
Types of window films – Overview and comparison
Windows are a key element in any building, from private homes to offices and commercial spaces. Their functionality and appearance can be significantly enhanced using various types of window films. Each kind of film has its own unique properties and applications, suitable for different needs and preferences. In this overview, we will discuss the most popular types of films, their benefits, and potential drawbacks.

Sun-blocking film for windows – Specifications and applications
This is one of the most popular types of window films. Its primary function is to reflect solar rays, which reduces interior overheating and helps save on energy costs. Sun-blocking film is available in various colours and degrees of tint, allowing for customization to meet individual aesthetic and functional needs.
The heat-reflective sun-blocking film is available in silver, platinum, blue, brown, green, and steel colours. However, it’s worth noting that the silver sun-blocking film typically provides the best effect.
Thermal insulation film – Pros and cons of isothermal film
To keep our homes, apartments, or offices warmer during winter, we can use isothermal window films. They operate on a principle similar to sun-blocking films, but their function is reversed – isothermal films retain heat inside rather than keeping it out. They are especially useful in buildings with poor thermal insulation or where solid fuels, which contribute to smog, are used for heating.
Isothermal film, also known as thermal insulation film, is usually available in neutral colours that don’t significantly alter the appearance of windows. However, this can vary depending on the manufacturer and specific product line.
UV protection film for windows – Characteristics and use
It’s well-known that ultraviolet (UV) radiation is harmful, as it can damage human and animal skin and harm the retina of the eye. One of the undesirable and destructive effects of such rays is the fading of objects exposed to sunlight and thus UV radiation. Therefore, an important function of UV protection film for windows is to hinder the penetration of these rays into homes, apartments, or office buildings.
This film is designed to block harmful ultraviolet radiation. It can stop about 99% of this radiation, creating healthier living conditions for the entire family.
Photochromic film – What is it?
This is an innovative type of film that changes its properties depending on the intensity of sunlight. On sunny days, the film darkens, providing visual comfort and reducing the heating up of rooms. It contains photochromic molecules that react to light levels – it remains transparent in darkness but begins to tint the windows as it gets brighter, changing to a darker colour. Under full sunlight, it becomes completely dark and opaque.
However, sometimes its ability to darken in response to sunlight may not be quick or effective enough during rapid changes in weather conditions, which can affect the comfort of using the spaces.

SONTE film – How does liquid crystal film work?
SONTE liquid crystal film represents a new generation of window technologies. It operates on the principle of electrically controlling liquid crystals that are sandwiched between layers of the film. When the electric voltage is off, the liquid crystals are disordered, making the film opaque and ensuring privacy. Turning on the voltage aligns the crystals, rendering the film transparent and allowing visibility.
Compared to other types of films, SONTE liquid crystal film offers unique advantages.
- Providing instant control over privacy and light, SONTE liquid crystal film goes beyond the capabilities of traditional window films. Unlike standard films that offer only a fixed level of tinting or protection, SONTE film allows for a dynamic shift from total transparency to full opacity in just a few seconds.
- It combines the functions of UV light protection and temperature regulation. It absorbs over 80% of UV radiation while still allowing sunlight to enter interiors, which is not only healthy for our skin and eyes but also highly practical.
- It does not negatively impact the aesthetics of windows, unlike some traditional films. Suitable for all kinds of windows and large glass surfaces, including skylights, this is an additional advantage.
In this way, SONTE liquid crystal film combines the benefits of other films while eliminating many of their drawbacks, making it a revolutionary solution in the field of window technologies.
How is liquid crystal film installed?
The installation of liquid crystal film does not require the replacement of glass in windows or glazings – it can be applied to any already installed single or double-glazed unit.
