There are an abundance of benefits that come from lining your windows with solar window film. Besides the cost savings, the interior of your house will also be more comfortable and less damaged by sunlight. That being said, there are a few drawbacks. These films are thin plastic or polymer layers that line your windows, controlling the amount of light or heat that is able to enter. Although new developments in solar film has solved many existing issues, there are still a few things to consider when choosing the right film.
The Uses of Solar Window Films
Solar window films were developed to limit the amount of light entering windows in order to ease heat and lengthen the appearance and lifespan of furniture affected by sunlight. They are “aftermarket” products, meaning that they are not part of the original windows, but rather applied later on. They are a great alternative to purchasing new windows. If you life in a warmer climate, it may be especially beneficial to you as the Window Film Association claims that these films provide the best return on investment, particularly in homes fitted with single-paned glass.
These polyester films have the ability to prevent long-wave infrared heat from going beyond the glass. Besides cooling the interior down in the summertime, these films also improve heat retention during colder months, allowing you to save money on electricity. They also impede UV rays from entering your home or office, saving your skin and your furniture. Nowadays, these films can also come clear rather than tinted, so you can still enjoy the bright natural light while not having to endure the heat that usually comes along with it.
When selecting a film, be sure to look for one that has been tested and certified by an outside party. Third-party testing helps you to ensure that the film is up to the standard when it comes to health and safety, such as fire safety and glass fragment protection. Additionally, it will also make sure that energy performance is up to par. The National Fenestration Rating Council is one of the more prominent third parties, having certified over 250 different films for their performance when it comes to energy.
Prior to making the purchase, also check that you have selected the right film for your climate. Take a look at the product information and note the visible transmittance (VT) and the solar heat gain coefficient (SHGC). Hot climates call for a VT value that is higher than SHGC, and vice versa.
Finally, take note of the light-to-solar-gain ratio. If your primary purpose of buying film is to keep heat out, choose a film with a ratio above 1. A high ratio such as this indicates that the glass is able to transmit more light than heat. In a cold climate, the opposite is true.
