It’s HOT! The sun is a necessity for life but at times a brutal beast. You don’t have to live in the desert to fully appreciate what the sun is capable of. As our Ozone layer continues to dissipate, we require a more proactive approach to solar protection and carbon neutrality. Blocking the sun while utilizing solar are all important factors in how we engage day-to-day. In our need to move towards a carbon-zero future, more energy-efficient buildings are taking precedent. Learning to control how the sun interacts with various buildings affords us all a better quality of life, and heat control window film can help.

What Heat Control Window Film Does

Heat control window film, also referred to as solar control window film redirects sunlight—thus, reducing heat within the structure. In general, heat blocking window films block out as much as 67 By blocking out approximately 97-99% of harmful UV sun rays, window film also reduces glare within the workspace. Additionally, this application allows more natural light to filter through deep into the interior of your building. Thus, providing those with a healthier environment in which to work.

That is an important factor in deciding to implement heat-blocking window film. Curtains or blinds have to be closed to help prevent your interior space from overheating. In doing so, they also keep out natural light that enhances our personal well-being and consequently, productivity.

These attributes alone are reason enough to implement heat control window film for your commercial buildings. By lowering the heat level of the building, particularly in warmer months, you increase your bottom line via a reduction in operating expenses. However, heat-blocking window film also helps prevent fading of your interior furnishings by blocking out infrared rays that are predominately responsible for heat exchange.

How Heat Control Window Film Works

Sun control window films are designed to reduce the amount of solar heat transmission through the glass, albeit windows or doors. This occurs by increasing the heat reflection, as well as solar absorption through the glass. Infrared light is responsible for more than 50 percent of heat inside. With this stated, by reducing the amount of heat that enters a building or structure, you improve your carbon emissions.

Many of the tinted films work via an increase in absorption. The color absorbs the solar energy at the point where it meets the glass. Reflective films are also effective in reducing heat and have their own set of benefits. These heat control window films are precision coated with various types of metals. Furthermore, this application allows more natural light to filter through deep into the interior of your building.

Benefits of Heat Control Window Film

Solar control window film affords various benefits that increase your energy efficiency, as well as improve your business’s bottom line. Typically, a building will see an ROI within 3 years of applying heat-blocking window film.

  • Lowers HVAC output, thus improving carbon emissions
  • Increases comfortability within
  • Reduces fading risk
  • Increases energy efficiency
  • Reduces heat transmission
