The Best Heat Reduction Window Film for Your Home

As the summer months approach, homeowners constantly search for ways to keep their homes cool without increasing energy costs. One of the most effective solutions is installing heat reduction window film.

At Concord Window Film, we understand the importance of maintaining a comfortable indoor environment, which is why we offer our top-of-the-line ceramic window film: ComforTech™ Ceramic Series designed to reduce heat.

What is Heat Reduction Window Film?

Heat reduction window film is a specialized film applied to windows to block a significant portion of the sun’s heat. This type of film works by reflecting and absorbing solar energy, which helps to keep your home cooler.

It’s an ideal solution for homeowners who want to reduce their reliance on air conditioning, lower energy bills, and create a more comfortable living space.

How Heat Reduction Window Film Works

Window film reduces heat by either reflecting it or absorbing it. Most films do a combination of both.

Benefits of Heat Reduction Window Film

Energy Efficiency

One of the primary benefits of heat reduction window film is improved energy efficiency. By blocking up to 99% of harmful UV rays and reducing solar heat gain, heat reduction window film can significantly decrease the need for air conditioning. This results in lower energy consumption and reduced utility bills

Enhanced Comfort

Installing heat reduction window film can help maintain a consistent indoor temperature, reducing hot spots and cooling rooms. This creates a more comfortable living environment, especially in rooms with large windows or those that receive direct sunlight during the day like East, South and West facing windows.

Protection from UV Rays

Excessive exposure to UV rays can cause fading of furniture, carpets, and other interior decor. Heat reduction window films block up to 99% of UV rays, protecting your valuable belongings from sun damage and prolonging their lifespan.

Improved Privacy

Certain types of heat reduction window films also offer increased privacy. These films come in various shades and reflective finishes, allowing you to enjoy natural light without compromising privacy.

At Concord Window Film, we have two solar control window films that offer heat reduction: our flagship product, ComforTech™ Ceramic Series Window Film and our Silver 15 Reflective Window Film.

ComforTech™ Ceramic Series Heat Reduction Window Film

Our ComforTech™ solar control ceramic window film is one of the best options for reducing heat while maintaining a clear view. Made with advanced ceramic technology, this film offers superior heat rejection, UV protection, and glare reduction while providing a neutral charcoal palette.

ComforTech™ comes in five shades (or colors) from lightest: 45 to darkest 05.  All of the shades offer solar control, but the darker the film, the better the heat reduction capabilities. For big heat issues where you want to block the most heat, ComforTech 05 and 15 offer the best performance.

ComforTech™ Solar Control Performance

According to the IWFA and NFRC, the two most important performance measurements for solar control window film are Total Solare Energy Rejected (TSER) and Solar Heat Gain Coefficient (SHGC):

  • Total Solar Energy Rejected is the percentage of the solar energy rejected by a filmed window to the total solar energy that hits the window. The higher the number, the more solar energy is rejected.
  • Solar Heat Gain Coefficient is a measure of how much solar radiation passes through a filmed window. Specifically, it indicates the fraction of solar energy that is admitted through a window, both directly transmitted and absorbed and subsequently released inward. SHGC values range from 0 to 1. The lower the SHGC, the less solar heat the filmed window transmits.

The chart below lays out the TSER and SHGC for ComforTech™ Ceramic Series film.

Silver 15 Reflective Film

For homeowners seeking maximum heat reduction at a lower price point, our Silver 15 Reflective film is a great choice. Using an older metal technology, Silver 15 is a mirror or reflective film with a shiny, silver finish.

It has a pressure-sensitive adhesive and is not dual reflective, so the same mirror effect will be displayed inside and outside the home as lighting conditions change.

How to Choose the Right Heat Reduction Window Film

Choosing the right heat reduction window film depends on several factors, including your specific needs, budget, and aesthetic preferences. Here are some tips to help you make an informed decision:

  • Choose the darkest film you feel comfortable with – the darker the film, the better the solar control and heat reduction
  • Dual reflective films have a lower indoor reflectivity, which is nicer for the inside of your home as night falls.
  • If you are installing yourself, a film with a dry adhesive is easier to work with than one with a pressure sensitive adhesive.

If you are unsure what film or shade of film is right for your home, take our product recommendation quiz to narrow down your options.

Then, to ensure the film matches your aesthetic before purchasing, order a window film sample kit. Tape the samples to your windows to see what the film will look like in your space. Be sure to view it from the inside and the outside and at different times of the day.
