Reflective films are specialized materials designed to reflect light and reduce heat transfer. They are commonly used in windows, vehicles, and buildings to improve energy efficiency by minimizing the amount of sunlight that enters a space. These films can also enhance privacy and reduce glare, making environments more comfortable. Typically made from polyester or other durable materials, reflective films come in various shades and levels of reflectivity. They can be applied directly to glass surfaces and are often used in conjunction with other energy-saving technologies. The effectiveness of reflective films can vary based on factors like climate and installation quality.
