Residential & Commercial FAQs
WHAT IS WINDOW FILM?
Sundown Window Film is a low-cost, high-return energy conservation measure made of micro-thin layers of film combined with high-performance coatings that bond to the glass surface.
WHY DO YOU NEED WINDOW FILM ON YOUR WINDOWS?
Adding Sundown Window Film upgrades your existing windows by improving energy efficiency, cutting glare and reducing damage to furniture due to fading. It also helps make occupants feel more comfortable within the building.
IS WINDOW FILM DISRUPTIVE TO INSTALL?
Most windows can be filmed in 15 minutes with minimal or no disruption to building occupants.
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%.
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!
IS APPLYING WINDOW FILM SAFE FOR MY WINDOWS? WON'T IT CAUSE GLASS BREAKAGE OR SEAL FAILURE?
The installation of window films is very safe. We provide our installers with a list of recommended applications and are confident that the applications are safe when the recommendations are followed. Plus, we provide warranties against glass breakage and seal failure.
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).
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.
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 IS THE EXPECTED LIFESPAN OF YOUR WINDOW FILM PRODUCTS AND WHAT ARE THE WARRANTIES ON YOUR PRODUCTS?
Most films carry a 10- to 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.
CAN WINDOW FILMS HELP WITH LEED CERTIFICATION OR QUALIFICATION AS AN ENERGY STAR LABELED BUILDING?
In fact, window films can assist with as many as 9 LEED Certification points (out of the 32 required for Silver LEED Certification). The energy savings provided by our films can also assist buildings with their Energy Star Labeling requirements.

Automotive FAQs
HOW DOES IT WORK?
We install a micro-thin film on the inside of your car windows. It has a patented adhesive system that bonds the film to the glass and can be placed on the back and side windows of your car.
DOES THE TINT HAVE TO BE DARK TO WORK?
It is a myth that window film has to be dark to be effective. State laws are in effect that outlaw very dark (black-out) window tinting. Our films come in several different light transmissions – all being neutral in appearance. Window film laws vary from state to state. Check your local laws to ensure that your selection is in compliance.
HOW LONG WILL THE WINDOW FILM LAST?
With proper installation by a trained dealer, your window film will last for a lifetime! We are so confident that our film won’t peel, bubble or crack that we back our product with the best warranty in the business.
WHICH MANUFACTURER DO YOU USE FOR YOUR WINDOW FILM?
We use Xpel, one of the world’s leading manufacturers of innovative window film. Xpel has engineered products to exceed expectations in industries across the globe.
WHAT TYPE OF RETURN ON INVESTMENT OR SIMPLE PAYBACK WOULD THESE ENERGY SAVINGS PROVIDE?

Many projects produce a simple payback in less than three years (when including utility company rebates) – equivalent to a 33% return on investment!
