• How does the installation of energy-saving window film affect the performance of my building's HVAC system?

According to U.S. Department of Energy statistics, solar heat gain through windows is responsible for about one third of a building's cooling costs. Energy-saving window film that can reduce solar heat gain by 75% or more can significantly reduce the run time of air-conditioning systems or allow them to operate at lower load conditions. This can reduce cooling costs in commercial buildings by as much as 30%, lengthen HVAC equipment life, lower maintenance costs for air-conditioning systems, and allow for replacement of cooling equipment with smaller, less expensive equipment.

• ​What type of return on investment or simple payback would these energy savings provide?

Though they provide similar energy savings, window films are much cheaper to install than replacement window - about 5-10% of the cost. Therefore, the capital investment is much lower for window film. Many projects produce a simple payback in less than three years (when including utility company rebates) - equivalent to a 33% return on investment!

• What level of energy savings can I expect with window films?

The energy savings depend on many factors, such as the existing type of glass, existence of overhangs, your location (climate), and energy rates in your area. However, for most buildings, high-performance window films can reduce energy costs from 5 to 15%.

​

• Does window film help reduce the heat in a room when the sun comes shining through?

Yes. Up to 75% of the heat is rejected by Window Film. You need not be afraid of installing beautiful windows for fear of too much heat.

• Can window film be installed on odd-shaped windows?

Yes. Vista™ Window Film is professionally installed and can fit virtually any size and shape of flat-glass window.

• ​Isn't window film dark? And won't application of film cause me to have to use more lighting, which would increase my energy costs?

In many cases, there is so much solar heat gain before window films are installed that shades or blinds must be kept closed. By applying energy-saving window film, blinds and shades can remain open, allowing more light into the building than before film installation. Plus, window films come in a variety of light transmissions, from very dark (0% light transmission) to very light (80% light transmission).

• ​What happens when a window breaks?

If the window breaks, the window film should hold the glass in place, thus reducing an incidence of injury or damage to furnishings.

• ​You say your products are energy-saving or "green." What measures has your company taken to save energy at your manufacturing facilities to show responsibility toward the environment?

In addition to complying with all applicable air and water safety standards for our manufacturing operations, over the past ten years Eastman Performance Films division has implemented a number of energy-saving measures. These have enabled Eastman to reduce the energy required per unit of production by nearly 40% during this period.

• Why is window film necessary if other window treatments are on the windows?

The sun will often damage window treatments such as draperies, curtains, blinds and shades. Window film helps protect furnishings, including window treatments.

• ​I've heard that films with a high Luminous Efficacy are the best films to use and will provide the best energy savings. Is this true?

Films with high Luminous Efficacies, also known as Spectrally-Selective Films, can be the best film in many applications. However, the solar heat rejection of these products is typically less than the highest performance films, so they offer less savings on air-conditioning costs. In addition, films higher in light transmission offer less in the way of glare reduction.

• Can window film help reduce the glare on my television and computer screens?

Absolutely. Window film reduces glare and helps eliminate eye fatigue.

FAQ's

​

• What is the expected lifespan of your window film products and what are the warranties on your products?

Most films carry a 10 or 15-year warranty for non-residential installations. Warranties include total film replacement, including labor and materials. Many of our films are on the job, still providing energy savings and improved comfort, 20 years after installation. (Some restrictions and limitations apply)
