FAQs
How does photochromic film differ from sun control film ?
While both films respond to sunlight, photochromic film changes its color based on sunlight or UV exposure—darkening when the sun is out and returning to clear when it’s not. Meanwhile, sun control film has a fixed tint, which means its appearance and performance stay the same, regardless of lighting conditions.
Why should I use photochromic film instead of traditional tinted film ?
Photochromic film offers both—crystal clarity when you want light and tint when you need privacy or safety. Traditional tinted film is always dark—even when the sun is out or it’s dark and cloudy, it never changes its appearance. Photochromic film adapts to the environment, making it ideal for the people who want natural light without glare or heat.
Does photochromic film help in energy saving ?
Absolutely! When the film darkens, it reduces the solar heat and keeps your place cooler without using or overworking the AC. This results in lower energy bills and more comfortable indoor environments.
Can photochromic film block UV and infrared radiation?
Yes, it can. Photochromic films are designed to block up to 98% of harmful UV rays and infrared radiation. This reduces sun damage and protects your floors, furniture, and fabrics.
