Heat insulation film for windows is a type of film used for applying to residential windows, designed to block heat from sunlight. Heat insulation films for residential windows are typically made from polyethylene terephthalate (PET) combined with various coating or treatment methods to provide heat blocking and sun protection properties.
In addition to its main function of heat insulation, window heat insulation films also have many other features: blocking harmful ultraviolet (UV) rays, reducing glare, limiting visibility from the outside, and enhancing the safety protection of tempered glass windows.
Window heat insulation films can be applied to various glass surfaces such as: window panes, glass doors, glass walls, glass roofs, skylights, etc. These films are considered one of the most effective ways to block solar heat for architectural glass in general, as well as for windows in apartments, condominiums, townhouses, villas, offices, etc. In addition to the films specifically designed for windows, there are also heat insulation films made specifically for cars.
Currently, window heat insulation films are known by various names in the market, such as: window film for residential windows, heat-blocking film, sun-blocking window stickers, window sun protection paper, heat-insulating sun-blocking window film, and window heat insulation film stickers.
Features of NanoX Window Heat Insulation Films
NanoX window heat insulation films offer 7 outstanding features: High-performance heat rejection of up to 90%, blocking infrared (IRR) rays by up to 100%, blocking ultraviolet (UVR) rays by up to 100%, high transparency, glare reduction, privacy protection, and glass protection.
High-performance heat rejection of up to 90%
The total heat rejection (Total Solar Energy Rejected – TSER) can reach up to more than 90%. NanoX window heat insulation films have a strong ability to reject heat by absorbing the heat from the sun that passes through the windows and then releasing it back into the external environment. This is achieved thanks to NanoX’s exclusive Nano Ceramic X-Shield technology, which helps create a perfect barrier to minimize the impact of the sun’s heat on the interior.

Infrared Rejection up to 100%
The ability to block infrared rays (Infrared Rejected – IRR) is as high as the absolute figure of 100%. NanoX heat insulation films do not block heat based on the usual principle of darkening, that is reducing the light passing through windows, glass walls, or glass ceilings… NanoX films block heat by completely filtering out infrared rays. This is because infrared rays carry the majority of the heat in sunlight. Thanks to this technology, NanoX also offers transparent, light-colored heat insulation films that still have excellent heat-blocking ability.

Benefits of Applying NanoX Heat Insulation Films for Windows
NanoX heat insulation films for windows operate based on the principle of preventing the transfer of heat between two environments separated by glass. The high heat from the sun’s rays is absorbed by the film and then released back into the external environment. Meanwhile, the cooler temperature inside the room, especially when using air conditioning, is retained, preventing heat loss.

Cooling the Space: Simply put, the main benefit of NanoX heat insulation films for windows is stabilizing the room temperature. This helps create a cooler environment, even when the temperature outside is rising. As a result, it provides a comfortable feeling, enhances physical and mental well-being, and minimizes the impact of fluctuating temperatures on the body.
Energy Savings: Stabilizing room temperature also brings another practical benefit, which is energy savings. By reducing the load on electrical appliances, especially air conditioners, it helps significantly lower monthly electricity costs.
Health Protection: Another important benefit of applying NanoX heat insulation films to windows is comprehensive health protection, especially for the skin and eyes. UV rays and blue light can easily pass through glass. Therefore, blocking UV rays and blue light thoroughly helps protect the skin and eyes, eliminating a factor that can harm both. Additionally, blocking UV rays helps preserve the durability and appearance of interior furnishings, preventing fading and damage.
Maintaining Natural Light: Maintaining natural light and visibility is also an advantage when applying heat insulation films to residential windows. NanoX’s heat insulation films for windows are designed to reduce glare effectively. Therefore, instead of completely blocking out the view like when drawing curtains, the film will not obstruct visibility while still regulating the light to the most comfortable level.

The operating principle of NanoX heat insulation films for windows:
NanoX heat insulation films operate by using ceramic-based technology, also referred to as engineered ceramics. One of the most remarkable characteristics of ceramic is its exceptional ability to effectively block the transfer of heat, ensuring optimal thermal protection.
This is made possible by the tight crystal structure of ceramics, which contains very few pores. The molecules are tightly bound, making it difficult for them to move and thus limiting heat transfer. In other words, compared to other materials, ceramics have a very low thermal conductivity, allowing heat to be transmitted at a very slow rate. Moreover, ceramics have the added advantage of high heat resistance. Due to the strong chemical bonds between the atoms, ceramics almost never change or deform under high-temperature conditions.
As a result, ceramics satisfy two key factors simultaneously: excellent heat insulation and high durability. This is precisely why NanoX has chosen ceramic as the primary material in the production of heat insulation films for residential windows.
Untreated glass
NanoX coated glass
NanoX heat insulation films operate by blocking heat transfer through the film by retaining heat within the film. It then releases the heat back into the environment outside, thus helping to keep the indoor temperature stable.
The technology used to produce NanoX residential window films
The range of NanoX residential window films is produced using Nano Ceramic X-Shield technology. This technology was developed exclusively by NanoX in collaboration with a team of experts from South Korea, tailored to the unique climate characteristics of Vietnam.
Nano Ceramic X-Shield uses advanced ceramic-based materials (Inorganic Ceramic) as the primary component for manufacturing window tint films for buildings. This material offers several key advantages: excellent heat insulation, high durability, user-friendly and safe for health, and non-interference with signals.
No signal interference
Metal-free & mercury-free
High durability
Health-safe
Notably, the ceramic particles are processed using advanced technology, achieving exceptional purity and an ultra-fine size of only 28 nm (instead of the typical 50-100 nm). This results in the formation of ultra-durable bonds, which significantly enhance not only the lifespan but also the heat-blocking performance of the film.
Advice for Choosing Window Insulation Films
Types of Window Insulation Films
Window insulation films for residential use are typically classified based on production technology, including four main categories:
Dyed Tint Films: This type of window insulation film features a PET layer that is treated with dyeing or coated with colored dyes on the surface. Dyed tint films primarily reduce heat by lowering the light transmission rate. However, the biggest drawback of this film is its relatively low ability to block infrared rays (IRR) and ultraviolet rays (UVR), along with limited durability.
Metalized Tint Films: This type of window insulation film is produced by coating a metal layer onto the surface of the PET layer. Commonly used metals include aluminum or nickel-chromium. Metalized tint films are more durable than dyed tint films, providing better heat insulation and ultraviolet ray (UVR) filtering. However, a drawback is that over time, the metal coating may oxidize and cause signal interference due to the metal components, resulting in lower durability.
Nano Ceramic Tint Films: This type of window insulation film is made from engineered ceramic materials. These films offer several advantages, including high durability, excellent heat insulation, and safety—being environmentally friendly and non-toxic upon contact. Particularly with high-end ceramic films, the transparency and clarity are very high, ensuring that visibility is not affected.
Nano Ceramic window tint films are the most popular choice for many people.
Hybrid Tint Films: This type of window insulation film is produced by combining two of the four technologies mentioned above. This combination helps to complement and address the drawbacks while enhancing the benefits of each technology. Typically, hybrid films combine dyed tint technology with metalized tint films or ceramic films with sputtered metal films.
So, which type of window insulation film is the best today? Among the window tint films used for sun protection in residential and office spaces, Nano Ceramic films and multi-layer sputtered metal films are the most popular. However, sputtered films have the drawback of being costly, which makes them less appealing to some customers. On the other hand, Nano Ceramic films offer excellent heat insulation, effective sun protection, and complete elimination of ultraviolet (UV) and infrared (IR) rays. With a reasonable price, they are a more popular choice.
