The Science Behind Heat Gain, How Window Tinting Can Help

Strong sunlight can have negative effects on a work environment

If you are looking for a way to reduce your business’s heating and cooling costs, reduce hot and cold areas in your home, or make an investment in your property, you should investigate the benefits of window tinting. Exploring the science behind tinting and heat gain can help clarify the positive effects that window tinting  provides.

Understanding the Solar Heat Gain Coefficient

Solar Heat Gain Coefficient, or SHGC, is a number between zero and one assigned to a window corresponding to what fraction of the heat from the sun the window allows to pass through. SHGC can vary from about .8 for normal clear glass to as low as .2 on very reflective tinted glass. Because most of the heat coming into a building enters through windows, SHGC  has a huge effect on a building’s heat gain and thus on how much energy is needed to cool it. On top of this, areas by windows tend to be much hotter than those elsewhere, so making a building more comfortable for a room in the sun would require you to cool the entire building down more. This wastes a lot of energy and cools areas which are not in sunlight to uncomfortably cold temperatures. This causes problems even in the winter as warmers areas near windows may become unpleasantly warm. Additionally, warmer regions will lose heat more quickly to the outside. Window tinting decreases the solar heat gain of windows, which lowers heating and cooling costs and reduces hot and cold areas in a building.

Benefits of Lowered Visual Transmittance

Window tinting also reduces the amount of bright sunlight that passes into a building. This is measured by a window’s Visual Transmittance, or VT, value. Like SHGC, VT is also a number between zero and one, this time corresponding to what fraction of the visual light passes through a window. Reducing the amount of bright sunlight that enters a building has several benefits. Bright light causes annoying glare on television and computer screens, which makes them much more difficult to use. This will often cause people to close blinds, eliminating all sunlight and wasting energy by relying solely on artificial sources. High levels of sunlight have also been shown to discolor and damage furniture over time. American Solar Tinting can work with you to determine the perfect level of window tinting for you to take full advantage of your natural solar light while reducing the negative effects that too much sunlight can cause.
