Window film blocks solar heat and glare, improving comfort and saving energy in commercial buildings. Learn how Avery Dennison Silver 20 film works.
Keeping Offices Cool: How Window Film Works
When the sun shines brightly over Ohio, many commercial buildings face a common challenge: excessive heat gain through windows. This project at John Glenn Columbus International Airport demonstrates how a strategic application of window film can provide significant relief.
Understanding Heat Through Your Windows
Windows, while offering natural light and views, are also a primary source of unwanted heat in commercial spaces. Sunlight contains infrared (IR) radiation, which is the heat we feel. Without treatment, much of this IR radiation passes directly through glass, increasing indoor temperatures and forcing air conditioning systems to work harder. This leads to higher energy bills and decreased occupant comfort.
The Role of Avery Dennison Silver 20 Film
The solution implemented here involved Avery Dennison Silver 20, a type of solar control window film. This film is designed with a micro-thin layer of metallization that reflects a significant portion of the sun's heat-producing IR rays.
- Solar Transmission: This film has a low Visible Light Transmission (VLT), meaning it allows less visible light through, which also helps reduce glare.
- Heat Rejection: Crucially, it boasts a high Total Solar Energy Rejected (TSER) rating. TSER measures the percentage of all solar energy that is blocked by the film. A higher TSER means more heat is kept outside.
- Appearance: The "Silver" in its name refers to its finish, which provides a neutral, reflective appearance from the outside. From the inside, it maintains a clear view, allowing occupants to enjoy the natural surroundings without the discomfort of intense heat and glare.
Benefits Beyond Heat Reduction
While the primary goal was heat reduction, window film offers additional advantages:
- Glare Control: By reducing the amount of visible light that enters, the film significantly cuts down on annoying glare, making it easier to work on computers and reducing eye strain.
- UV Protection: Most solar control films block over 99% of harmful ultraviolet (UV) rays. UV radiation can fade carpets, furniture, and artwork over time.
- Energy Savings: By reducing the load on HVAC systems, window film can lead to noticeable reductions in energy consumption, especially during Ohio's hot summer months.
