Should You Apply Insulation Film to Residential Glass Windows?

While popular worldwide, window insulation film is still relatively new in Vietnam—leading many to ask: Is it truly effective?

Among heat-reducing solutions for homes, insulation film is modern, efficient, and easy to apply. It significantly lowers heat transfer through glass, with proven results users can feel immediately. Beyond heat control, it also enhances comfort, saves energy, protects interiors, and improves privacy.

Key Benefits of Window Insulation Film

• Heat Rejection & Cooling Effect: Insulation film works by absorbing and reflecting heat, preventing solar heat from penetrating indoors. This helps maintain a cooler and more comfortable home environment.
• Infrared Radiation (IR) Blocking: IR radiation is the main cause of heat from sunlight. Premium window insulation films can filter infrared rays, maximizing overall heat rejection.
• Ultraviolet (UV) Protection: UV radiation not only causes skin damage and health issues but also fades interior furnishings. High-quality insulation films can block 99–100% of UV rays, ensuring protection for both people and property.
• Glare Reduction: Insulation film helps regulate light, reducing glare from direct sunlight and enhancing indoor comfort.
• Energy Savings: By maintaining a stable indoor temperature, window insulation film reduces the workload on air conditioning systems, leading to optimal energy savings.
• Enhanced Privacy: By utilizing the difference in light levels between indoor and outdoor environments, insulation film can limit visibility from the outside, increasing privacy and security.
• Glass Safety Reinforcement: Insulation film can also act as a protective layer, strengthening glass and minimizing risks in case of breakage or shattering.

Meaning of Window Insulation Film Technical Specifications

The technical specifications of window insulation film indicate its ability to block heat, infrared (IR) rays, ultraviolet (UV) rays, light transmission, reflectivity, and other properties.

• Total Solar Energy Rejected (TSER) – Heat Rejection: Indicates the film’s ability to reduce heat passing through the glass.
• Infrared Rejection (IR): Shows the film’s capability to block infrared rays from passing through the glass. IR rays are the primary source of heat in sunlight.
• Ultraviolet Rejection (UV): Represents the film’s effectiveness in blocking UV rays, which can cause skin damage, eye problems, and other health issues.
• Visible Light Reflectance (VLR) – Reflectivity: Indicates the level of reflectivity or mirror effect of the film.
• Visible Light Transmission (VLT) – Light Transmission: Measures how much light passes through the film, determining its brightness or darkness.

Experience in Installing Window Insulation Film

When applying insulation film to glass doors and windows, it is necessary to consider the following factors to choose a high-quality product.

Choosing by Manufacturing Technology

Window insulation films are classified into five main production technologies:

• Dyed Tint Film
• Metalized Tint Film
• Sputter Tint Film (Multi-layer Metal Sputtering)
• Nano Ceramic Tint Film
• Hybrid Tint Film

Which type of window insulation film is the best today?

Among the available options, ceramic films (Nano Ceramic) and multi-layer sputtered metal films (Sputter) are the most popular. However, sputtered films have the disadvantage of being expensive, making them less accessible to some customers. Ceramic films, on the other hand, offer good heat insulation, effective heat resistance, and a long lifespan, while being reasonably priced, making them a more popular choice.

Choosing based on building function

Window insulation films can be used for apartment glass, residential glass, townhouses, villas, offices, restaurants, hotels, shops, cafes, etc. However, depending on the function of each building, there will be specific types of window insulation films.

Currently, the market typically separates two main groups: residential glass films and office glass films. For office films, most projects use large volumes, so cost, particularly price, is a priority. In contrast, residential films focus on enhancing the user experience. Specifically, in addition to heat insulation, they often require many additional features such as UV protection, high transparency without affecting the view, and increased privacy.

Within each group, there are various types that meet different requirements. For example, within the office window sun protection film group, films for stores or shopping centers need to be clear so that people outside can easily see the products displayed inside. Meanwhile, films for restaurants, cafes, etc., will focus on sun protection and glare reduction.

Therefore, depending on the specific function of each building, it is necessary to choose the appropriate type of film. Even when prioritizing heat resistance, the chosen window sun protection film should not negatively impact the activities and experiences within the building.

Choosing based on window location

The window location is one of the top factors to consider when applying window film, as it affects the effectiveness of use. Residential windows have many different functions and locations such as glass windows/glass walls, entrance glass doors, skylight glass roofs (glass domes), outdoor glass roofs/balconies, etc.

For example, even within apartment windows, living room windows often need more natural light, while bedroom windows prioritize privacy. Therefore, heat-insulating films for living room windows should allow more light to pass through to both illuminate and maintain the view. For bedrooms, heat-resistant films combined with anti-peeping features are preferred.

Choosing based on sunlight direction

The direction of sunlight directly affects the amount of heat that enters the house through the windows. Specifically, the East receives early morning sun, with temperatures rising quickly but also dropping quickly. Conversely, the West receives strong afternoon sun, absorbing the most heat and keeping the house hot for longer, extending into the evening. The South receives consistent sunlight throughout the year but is not too intense. The North is the least affected by hot sunlight.

Therefore, when applying heat-resistant films to residential windows, it is necessary to consider the direction of sunlight on the windows. For example, if you want to protect a west-facing house from heat, you should choose a window insulation film with high total solar energy rejection (TSER) and anti-glare properties. This is because glass exposed to direct sunlight from the west tends to absorb a lot of heat and cause glare.

Choosing based on technical specifications

Window insulation films primarily function to protect against heat. Additionally, they offer many other features such as infrared (IR) rejection, ultraviolet (UV) rejection, high light transmission & transparency to maintain the view, anti-peeping, glass protection, etc. Corresponding to these features, there are specialized product lines, all of which are clearly indicated in the film’s technical specifications. Therefore, an important tip for applying heat-insulating film is to choose a film with specifications that closely match your actual usage needs.

For example, when you need to apply window film but still maintain the view and avoid changing the color of the glass, you should choose window films with high light transmission, transparency, and infrared rejection. If you prioritize health protection and the protection of interior furniture and equipment, films that block 100% UV rays are the best choice.

If you want to combine sun protection, anti-glare, and anti-peeping features, you can prioritize films with low light transmission, dark colors, black colors, or high reflectivity. If you also want to combine heat resistance and glass protection, choose the thickest film possible, ideally 2 mil or more.

Choosing based on color

Window insulation films come in many different colors. The most popular colors include brown tea, gray, black, blue, green, etc. You can choose the film color based on the interior and exterior space or the homeowner’s preference.

For example, if the interior is white-gray, you should choose a gray film. If you like a cool and comfortable feeling, you can choose a blue film. If you prioritize privacy, you can choose black window insulation films.

How to Check the Quality of Window Insulation Film

There are many ways to check, identify, and distinguish between high-quality and low-quality window insulation films.

• Check technical specifications: The technical specifications of the film can be checked using specialized industry measuring tools and equipment.
• Check heat rejection: The actual heat insulation effectiveness of the film can be tested using infrared lamps, demo application, and direct measurement with a thermometer.
• Check transparency: The higher the quality of the window insulation film, the higher its transparency. Therefore, it is necessary to carefully check the transparency of the film, avoiding choosing blurry, hazy, or glaring films that affect visibility.
• Check brand logo: Most genuine window insulation films have the brand logo and product code printed on them.
• Check in reality: Carefully observe the current condition. A high-quality insulation film will not have scratches, ripples, uneven colors, or peeling adhesive.
• Check warranty policy: Reputable insulation film brands have clear warranty policies and provide a warranty card after purchase. Some brands even offer electronic warranties.
• Check the reputation of the brand/distributor: It is advisable to choose window insulation films from reputable brands and official distributors with transparent information.

Should You Apply Window Insulation Film by Yourself at Home?

Applying sun-blocking window film requires full preparation of tools, especially specialized film application squeegees. In particular, besides mastering the method of applying window insulation film, the installer must also have a certain level of experience to achieve durability and high aesthetics. If applied incorrectly, the film is very prone to defects such as air bubbles, dust, wrinkles, and misalignment.

The current price lists for window insulation film usually include installation costs. Therefore, the ideal option is still to choose a full-service window insulation film application. Using this service ensures professional consultation & installation as well as long-term warranty in case of defects.
