Glare Reducing Window Film: A Complete Guide

Glare from windows can be a real nuisance, whether it’s affecting your work on a computer, making it hard to watch TV, or simply causing discomfort in your living spaces. Fortunately, there’s a solution: glare reducing window film. In this comprehensive guide, we’ll walk you through everything you need to know about this innovative solution for a more comfortable and glare-free environment.

What is Glare?

Glare refers to the excessive brightness or blinding light that can make it difficult to see or focus, causing discomfort or strain to the eyes. It’s often caused by direct sunlight or bright artificial light sources that create reflections on surfaces like windows, screens, or shiny objects. Glare occurs when the intensity of the light overwhelms the eyes, making it challenging to see clearly and comfortably. Glare can impact visibility, hinder tasks like reading or driving, and lead to eye fatigue or discomfort.

What is Glare Reducing Window Film?

Since glare and heat come from the same sources, most solar control window films have good glare control.  Window film is applied to glass surfaces to reduce the intensity of incoming light and minimize glare. It is designed to improve visual comfort by controlling the amount of sunlight that enters a room without compromising the view or the quality of natural light.

How Does Glare Reducing Window Film Work?

Glare reducing window film works by utilizing advanced technology that selectively filters and absorbs light waves. This film contains microscopic layers that can block specific wavelengths of light, such as ultraviolet (UV) rays and certain portions of the visible spectrum. As a result, the film reduces glare and excessive brightness, creating a more comfortable environment.

Our ComforTech™ Ceramic Series film has nano ceramic particles that reflect and absorb the sun’s light to reduce glare. Our Silver 15 Reflective film has metallic particles that reflect the sun’s light to reduce glare.
