Learn how window film reduces glare and heat, using a real airport installation as a worked example. Improve comfort and efficiency.
How Window Film Reduces Glare for Businesses
Window film is an effective way to manage sunlight and improve comfort in commercial buildings. This guide explains how it works, using a recent installation at John Glenn Columbus International Airport as an example.
Understanding Glare and Solar Heat
Glare is caused by direct sunlight entering a building and reflecting off surfaces. It can cause discomfort, reduce visibility, and contribute to eye strain. Intense glare, like that experienced by businesses near airport runways, can significantly impact daily operations.
In addition to glare, direct sunlight also brings solar heat into a building. This heat can raise indoor temperatures, making spaces uncomfortable and increasing the demand on air conditioning systems.
The Science Behind Window Film
Window films are thin layers of polyester or other materials applied to glass. They work by manipulating the light and heat that passes through the window.
* **Reflection:** Many films have reflective properties that bounce a portion of the sun's energy back outside before it can enter the building. Avery Dennison Silver 20, used in the airport project, features a metallic layer that reflects solar radiation. * **Absorption:** Some films absorb solar energy, converting it into heat that is then dissipated. * **Filtering:** Films can filter out specific wavelengths of light, such as ultraviolet (UV) rays, which are harmful to both people and furnishings.
Measurable Results with Window Film
For the installation at John Glenn Columbus International Airport, Avery Dennison Silver 20 film was chosen to address intense glare on windows facing the runway. This film is designed to block a significant amount of solar energy.
While specific Visible Light Transmission (VLT) and Total Solar Energy Rejected (TSER) for this exact application aren't detailed here, films like Silver 20 typically offer substantial glare reduction. This means less direct light entering the space, improving visual comfort for those working or present in the area. By reducing the amount of solar heat entering, it also contributes to a more stable indoor temperature.
Choosing the Right Window Film
Selecting the appropriate window film depends on the specific needs of the property. Factors include the desired level of glare reduction, heat rejection, privacy, and aesthetic preferences. For commercial properties in Ohio seeking to improve comfort and energy efficiency, exploring options like [commercial window tint]( /commercial-window-tint-dayton-ohio) is a valuable step. Consulting with a professional installer can help determine the best solution for your unique situation.
