Avery Dennison SP E Lite 70i window film was installed in Cincinnati to reduce glare and heat, maintaining a natural look.
How Window Film Reduces Glare and Heat##\n\n
Window film is a thin, transparent or tinted layer of polyester applied to the interior or exterior of glass. It works by altering the way sunlight interacts with your windows. This project in a Cincinnati penthouse aimed to reduce intense glare and heat, common issues in high-rise living, especially on sun-facing exposures.\n\n
Understanding the Science Behind Window Film###\n\n
Window films work through several mechanisms:\n\n Reflection: Some films reflect a portion of the sun's energy away from the building before it can be absorbed by the glass.\n Absorption: Other films absorb solar energy, which is then re-radiated, with a portion directed outward.\n Low-E (Low Emissivity):* Advanced films, like the Avery Dennison SP E Lite 70i used here, often incorporate Low-E technology. Low-E coatings are microscopically thin, transparent layers that reduce heat transfer. In summer, they reflect solar heat away from the building. In winter, they help keep interior heat inside by reflecting it back into the room. This dual-action capability makes them effective year-round.\n\n
Glare Reduction###\n\n
Glare is caused by excessive amounts of visible light entering a space. Window film reduces glare by lowering the amount of light that passes through the glass. This is measured by the Visible Light Transmission (VLT), which indicates the percentage of visible light that passes through the film and glass. A lower VLT means less light and less glare. The Avery Dennison SP E Lite 70i has a high VLT, meaning it allows most visible light through, but it still effectively reduces the intensity of the light, thereby reducing perceived glare without significantly darkening the interior.\n\n
Heat Reduction###\n\n
The sun's energy includes infrared radiation, which is the primary source of heat. Window films manage this heat through Total Solar Energy Rejected (TSER) and Solar Heat Gain Coefficient (SHGC). TSER measures the total amount of solar energy that is blocked by the film. SHGC is the fraction of solar heat that enters through the window, including absorbed and transmitted heat. Films with a higher TSER and lower SHGC are more effective at reducing heat gain. The Avery Dennison SP E Lite 70i was chosen for its ability to manage solar heat without drastically altering the window's appearance, providing a more comfortable indoor environment.\n\n
Why Choose Window Film?###\n\n
For property owners in Cincinnati and surrounding areas like Dayton, Ohio, window film offers a cost-effective solution to improve comfort and energy efficiency. It can reduce cooling costs, protect furnishings from UV damage, and enhance privacy, all while maintaining the aesthetic of your building.
