Window films reduce the excessive solar heat and glare from any existing window. They block infrared radiation from penetrating your home during summer and generate sufficient heat to cut your heating bills in the winter. With today's skyrocketing utility and house maintenance costs, many homeowners realise the importance of having energy-efficient homes. Window films are not just cost effective but are also environmentally friendly.

Common Features of Window Films

In addition to providing energy efficiency, window films or glare control window films are also fast and easy to install. In most cases, anyone can install window films by following the manufacturer's instructions. They have the same features as car window films that reduce the effects of ultraviolet (UV) rays. Window films effectively block off most infrared radiation without necessarily turning your home into a dark room. They can also prevent excessive heat loss during winter. Window films come in different sizes and brands. Other varieties, such as solar films and solar screens, offer the same heat management solutions. They secure optimum heat levels when the temperature gets cold while lessening the excessive heat from the glaring and scourging rays of the sun.

How to Choose the Right Window Film

Look for the total heat reflected and rejected when shopping for window films. By definition, reflected heat refers to the solar rays that window films can bounce off while rejected heat pertains to infrared light that the window films can absorb and give off. Infrared light is the same light that heats up your home. Choose the ones with moderate reflectivity and rejection rates to regulate or control the heat that comes in and out through your window panes. You may also want to look for the Visible Transmittance (VT) value for the film after applying it to a clear window glass pane. Review the manufacturer's warranty before applying the film on your window, and look for the Solar Heat Gain Coefficient (SHGC). You have the right material if the VT value is greater than the SHGC value, according to the University of Central Florida.

Benefits of Using Window Films

Window films reduce energy costs normally needed for cooling purposes. Most brands are easy to install and remove to allow the sun to warm your home during winter. By maintaining just the right level of heat in your home, the entire household will benefit from healthy physical and mental conditions by reducing stress brought about by extreme or lack of indoor heat. Too much heat will also damage home furnishings and even electrical appliances. Window films minimise the effects of UV rays that can ruin furnishings, flooring material and other items in your home. And window films add privacy to your home by blocking the view into your home.

Disadvantages of Window Films

Window films have the tendency to darken your window view. Permanent solar window films may deter the heat of the sun to penetrate your windows when you need it most -- for example, during wintertime. For this reason, choose the right solar window film that would work best for your location to eliminate unnecessary costs in the future.
