Heat reducing film

Information

Heat rejection window film is a thin layer of material that is applied to the interior or exterior of a window. It's designed to reduce the amount of heat and UV rays that pass through the glass, making it an ideal solution for keeping your home cool during the summer months. Window film can also reduce glare by up to 95%, improve privacy and increase the security of your home.

Net Curtains/Blinds vs. Window Film
Light Filtering.

Tightly woven net curtains: Allow some natural light to pass through, varying with weave and density. They may not be suitable for glare control. Typically have a Visible Light Transmission (VLT) of 10% to 30%.
Loosely woven net curtains: These curtains have a higher VLT of 30% to 50%.

Venetian blinds: have a 20-50% VLT, depending on the material and slat width.
Roller blinds: 10-70% VLT, depending on the fabric.
Vertical blinds: 30-50% VLT.

A clear toughened double glazed window has a VLT ranging from 70% to 80%.

Window Film: Offers a wider range of light filtering options, from light diffusing to significant light blocking. Some films provide glare reduction for comfortable viewing. Our dual reflective 25 has a VLT of 27%, other films vary from 8% to 35%.
All tinted window films will reduce fading by 70-80%.

+Higher VLT means more light passes through, resulting in a lighter appearance. Lower VLT means less light passes through, resulting in a darker appearance.

Visual Acuity
(Important when looking at a window film sample on a window)

The human eye has a logarithmic response to light, which means that small changes in light levels at low light levels are more noticeable than at higher light levels. This phenomenon is known as the Weber-Fechner law.

So, when a window film with a 30% VLT rating is applied, it blocks 70% of the light from passing through. However, the reduction in perceived brightness by the human eye might not be as significant as the percentage of light blocked. Due to the logarithmic response of the eye, the perceived reduction in brightness might be closer to 7% or even less.

This means that even though the VLT rating suggests a substantial reduction in light transmission, the actual impact on the perceived brightness might be relatively minor. It's an important consideration when evaluating the visual effects of window films.


Window film is a cost-effective solution for keeping your home cool and comfortable during the summer months. It's energy-efficient, provides protection from harmful UV rays, increases privacy and enhances the security of your home.
