Solar Window Film

The efficacy of solar window films in numbers:

Depending on the model, these tinting solutions, including solar reflective window film, can block up to 80% of sunlight and reflect up to 90% of solar heat penetrating through the glass. The effectiveness may vary based on geographical latitude, solar angle incidence, and window design.

Key Technical Indicators: Glass Film Sun Protection

Solar films for windows come with technical data, allowing for an evaluation and comparison based on standardized parameters. The primary indicators are VLT% and IR%, measured in percentages.

• IR% - solar heat reflection. A higher IR% indicates that the solar window film more efficiently reflects solar heat. For instance, if IR is stated as 80%, it means the tint reflects 80% of solar heat while letting through 20%.
• VLT% - sunlight transmission. It indicates the percentage of sunlight the film allows through, and to what extent it darkens. A higher VLT% means the film is lighter. For example, if VLT is 35%, the solar protection film only allows 35% light transmission, darkening by 65%.

It's essential to understand that darker solar control window films (with higher VLT) have a higher percentage of IR. When choosing tints, attention should be paid to both these indicators to find a balance between IR and VLT.

Sun Protection Glass Film 10%, 20% or 35%

Sun protection films can be broadly grouped based on light transmission:

• 10% are very dark, used on rare occasions
• 20-25% are dark
• 35-50% are light
• 60-80% are very light and barely noticeable or even more so

This classification is quite approximate and is based on our extensive experience. When selecting solar window films, it is advisable to consider the window size. Larger windows generally require darker coverings (with higher VLT), meaning, darker coverings are usually selected.

Diverse Colour Range of Sun Blocking Window Film

The market and online retail spaces offer solar films in a variety of colours, albeit with a limited selection due to the intricacy of the technology involved. The primary colours include:

• Silver
• Bronze
• Gold
• Semi-transparent and virtually colourless heat reflective window films.

These colour variants are available in our inventory and can be ordered by the linear metre, cut to size, or in rolls.

Solar Films for Windows 10-20%

The most effective sun blocking films are the darker, highly metallised solar window films. For larger windows, darker films are necessitated. A standard choice would be a window solar film with a 20% tint, ensuring a reduction in solar impact along with maximum protection from glare and UV radiation.

For Larger Windows (e.g., 1.6 metres by 2 metres or similar)

• Omg 20% in silver for internal application
• Omg 20 EX glass film sun protection in silver for external application
• Bronze AT 20 EX solar glass film in bronze for external application
• Omg 10% in silver (very dark, mostly used for technical rooms)

Sun Reflective Window Film 35-45%

These are relatively light films, often chosen for windows of smaller dimensions or if there's no desire to significantly darken the glass. These solar reflective window films mitigate solar heat without substantially dimming sunlight and the indoor illumination as a result.

For Smaller Windows (e.g., 1.4 metres by 0.8 metres or smaller)

• Omg 35%, glass film sun protection in silver for internal application
• Omg 30% EX solar reflective window film for external use
• Bronze AT 35 EX glass film sun protection in bronze for external application
• Infinity 45% window solar film in semi-gold for internal application

These coverings, including solar reflective window film, are selected if there's a desire to reduce the heat from sunlight without fearing a darkened aftermath following the covering installation.

Solar reflective window film 50-60%

Light tints reduce heat by 3-5 degrees but barely darken the glass, making them a compromise solution. Solar reflective film of 50-60% will not provide substantial heat protection but will maintain the sunlight passing through the glass, preserving the room's brightness.

• Bronz AT 50 EX window solar film in light bronze for external application
• Omg 50% glass film sun protection in light silver for internal application
• Jubilee 60% -light window solar film for internal application

These tints, including the glass film sun protection, also exhibit a mirrored effect, albeit very subtly expressed.

Important Note!!!

Many believe that automotive tint coverings can be employed on building windows. THIS IS INCORRECT! Car tinting is usually black and induces glass heating. They absorb more heat than they reflect. Automotive glasses can withstand any degree of heating (automotive glasses are tempered). On the other hand, solar reflective window film is designed to reflect solar heat, making it a suitable choice for building windows.

Decorative and matte tint do not reflect solar heat as they lack a metallised layer, unlike the solar reflective window film which has a metallised layer to reflect a higher percentage of solar heat. Review the technical data, and you'll observe that their heat reflection percentage is minimal compared to that of solar reflective window film.

For shielding building windows from the sun, among the entire assortment of window films, it is imperative to use heat reflective films specifically. This ensures the desired effect and safeguards your windows!
