How Window Film Reduces Heat Gain
Window tint, also known as window film, is a thin laminate applied to the interior or exterior of a window. It works by altering how sunlight interacts with the glass. Different types of window films are designed to manage specific aspects of solar energy.
Understanding Solar Heat and Light
Sunlight contains visible light, infrared (IR) heat, and ultraviolet (UV) rays. IR heat is the primary cause of unwanted heat gain in buildings, making spaces feel warmer. UV rays can cause fading of interior furnishings.
Types of Window Film for Heat Reduction
### Solar Control Window Films These films are designed to reflect a portion of the sun's energy before it enters the building. They achieve this through micro-thin layers of metals, dyes, or ceramics embedded within the film.
- Tint: The darkness, or Visible Light Transmission (VLT), of a film is a key factor. A lower VLT means less visible light passes through, which often correlates with higher heat rejection. However, advanced films can offer high heat rejection with minimal tint.
- Total Solar Energy Rejected (TSER): This is a crucial metric indicating how much of the total solar energy (light and heat) the film blocks. A higher TSER means more heat is kept out. For example, a film with a 60% TSER will reject 60% of all incoming solar energy.
- Solar Heat Gain Coefficient (SHGC): This measures how much solar heat is admitted through the window. A lower SHGC is better for reducing heat gain.
