When choosing window films, the amount of light you allow into your space is a matter of personal preference and practical considerations. Understanding Visible Light Transmission (VLT) is crucial for selecting the right film for your specific needs. 

 

What is VLT? 

Visible Light Transmission (VLT) measures the percentage of visible light (the part of the light spectrum humans can see) that passes through a window film. It’s typically expressed as a number between 0 and 1 or as a percentage. 

  • Higher VLT: Allows more natural light to enter the space, making it brighter and more inviting.
  • Lower VLT: Blocks more light, reducing brightness and providing greater privacy or glare control.

 

Balancing Light and Heat 

While maximizing natural light with a high-VLT film may be desirable, it’s essential to consider the trade-off: increased solar energy gain. More sunlight can lead to higher indoor temperatures and added strain on cooling systems. 

The good news? Modern window films are designed to strike a balance between VLT and solar energy rejection. Advanced technologies, such as ceramic and nano-ceramic films, enable you to enjoy bright, naturally lit spaces without compromising on energy efficiency or comfort.
