Films to block RadiatioN and heat
Films designed to block radiation and heat from the sun, often referred to as "Anti-Sun," have been available since the early 1970s.
This field has seen continuous technological advancements, with ongoing improvements in the quality of the films to enhance heat and glare rejection while ensuring greater durability over time.
Anti-Sun films are among the most effective solutions for protecting against radiation, glare, and heat buildup in offices and buildings. Window shading is achieved using a special material that blocks over 99% of incoming radiation.
Anti-Sun films are highly popular in stores, public buildings, shopping malls, and even private homes.
TECHNOLOGY
Sources of Heat and Radiation
Heat comes from three primary sources:
- UV (Ultraviolet): 10%
- Visible Light: 45%
- IR (Infrared): 45%
Blocking heat and radiation eliminates the need for curtains or blinds, allowing work on computers without glare or brightness issues (even on the non-sun side).

- Low durability (fades in one year) and contains hazardous adhesives like formaldehyde and benzene.
2. Second Generation: Dyeing Film
- Dye applied directly to the adhesive layer, offering limited thermal and UV insulation.
- Moderate lifespan (two years) but low definition and hazardous adhesives persist.
3. Third Generation: Vacuum Aluminium Plating Film
- Utilises vacuum thermal evaporation to coat aluminium on the film base.
- Offers moderate thermal insulation, higher durability (five years), and improved definition.
4. Fourth Generation: Nano Ceramic Film
- Employs coating or magnetron sputtering to evenly distribute nano ceramic particles.
- Absorbs heat effectively, offers over seven years of durability, and does not interfere with wireless signals.
5. Fifth Generation: Magnetron Sputtering Metal Film
- Uses electromagnetic induction to apply precious metals (gold, silver, titanium, nickel).
- Provides better definition, higher thermal insulation, and lasting durability (over seven years).
6. Sixth Generation: Multi-Layer Magnetron Sputtering Metal Film
- Sprays multiple layers of precious metal alloys using electromagnetic induction.

What is the most important parameter to measure heat?
Total Solar Energy Rejection (TSER) is the most crucial parameter for measuring heat.
It represents the percentage of solar energy blocked by the film, including visible light, infrared, and ultraviolet radiation.
A higher TSER indicates better heat reduction capabilities.
What is exactly VLT?
VLT, means Visible Light Transmission, measures the percentage of visible light that passes through the window film.
For example, a 5% VLT means only 5% of visible light passes through, while 70% VLT allows much more light to enter.
Lower VLT means darker film.
What is the Ultraviolet (UV) range?
The UV (Ultraviolet) spectrum typically ranges from 100 nm to 400 nm. Here's a breakdown of the different sub-regions of the UV spectrum:
UV-A (Long-wave UV): 320 nm to 400 nm
This is the least energetic and longest wavelength UV radiation.
UV-B (Medium-wave UV): 280 nm to 320 nm
his range is more energetic and is responsible for sunburns.
UV-C (Short-wave UV): 100 nm to 280 nm
This is the most energetic and harmful form of UV radiation, but it is almost completely absorbed by the Earth's atmosphere.
What is the Infrared (IR) range?
Infrared (IR) radiation is a portion of the electromagnetic spectrum that lies beyond the red end of the visible light range and extends to longer wavelengths. Generally, the infrared region covers wavelengths from about 700 nanometers (nm) to 1 millimeter (mm), although the exact boundaries can vary slightly depending on the classification system used.
To further break it down, the infrared spectrum is often subdivided into several regions:
Near-Infrared (NIR):
Approximate range: 700 nm to 2.5 micrometers (µm)
Close to the visible spectrum and commonly used in fiber-optic communications, medical imaging, and remote-sensing applications.
Mid-Infrared (MIR):
Approximate range: 2.5 µm to 25 µm
Includes the thermal imaging region and is strongly associated with the vibrational modes of molecules, making it useful for spectroscopy and chemical analysis.
Far-Infrared (FIR):
Approximate range: 25 µm to 1 mm
Corresponds to lower-energy, longer-wavelength radiation often emitted as thermal radiation by objects at or near room temperature. This region is used in studying the thermal properties of materials, astronomical observations, and certain applications in climate and weather research.
Why do some films have metal, and what is its role?
Metallic films contain thin metal layers that reflect solar radiation.
The metal helps to:
Increase heat rejection

What is a low-E layer? Is it like an anti-sun film?
A low-E (low-emissivity) layer is a thin, transparent coating applied to glass to reduce heat transfer. It works by reflecting infrared (heat) energy while allowing visible light to pass through, similar to an anti-sun film but more advanced.
Key Points:
Purpose: Reduces heat loss in winter and heat gain in summer, improving energy efficiency.
Application: It is usually applied during the manufacturing process as part of the glass itself, not after installation (unlike aftermarket window films).
Technology: Made from ultra-thin metal or metal oxide coatings.
This makes low-E glass ideal for energy-efficient windows in homes and buildings.

TECHNOLOGY
Solar Parameters
TSER (Total Solar Energy Reflectance) is a measure of the reflectivity of a surface for solar radiation, and it is often expressed as the sum of the reflectance across different spectral bands. The formula to compute TSER from the reflectance values in different spectral bands (VLT, IR, and UV) typically involves taking the weighted sum of reflectance across those bands, with the weights representing the relative contribution of each spectral range to the total solar radiation.
If we define:
-
Visible light (VLT): The visible light part of the spectrum generally covers the range from about 400 nm to 700 nm.
-
UV (Ultraviolet): The UV spectrum typically includes wavelengths from about 100 nm to 400 nm.
-
IR (Infrared): The infrared spectrum is generally considered to cover wavelengths from 700 nm to 2500 nm.
Then the formula for computing TSER is generally:
TSER= 43% x VLT + 52% x (1 - IR rejection) + 5% x (1 - UV rejection)
A higher TSER (Total Solar Energy Rejected) means the window film or glazing is better at rejecting solar energy
TSER and SHGC Relationship:
TSER and SHGC measure related but opposite effects: TSER represents the percentage of solar energy rejected, while SHGC indicates the fraction of solar heat allowed inside; together, they sum to 100%.
Thus:
TSER = (1 - SHGC) * 100%
In practical applications, the exact values for α depend on the specific material, and the SHGC will often be calculated taking into account both transmitted and reflected radiation, as well as other thermal properties.
