What is window film?

Window film is a polyester base material, sometimes referred to as Polyethylene Butylene. This material starts out as a clear product with various metal, oxides or nano particle technology added to it to block UV and infrared rays and glare from the sun.

Will window film save money on my energy bill?

Yes, window film can help you save money on energy costs. When installed in residential and commercial buildings, window film reduces the amount of the heat transfer through the windows in the summer, reducing the energy needed to cool the space. In the winter, the window film can help keep heat in, reducing the energy needed to heat the space. Llumar Window Films block up to 99.9% of UV rays and reject up to 80% of the sun’s heat. The exact amounts blocked, as well as the amount of visible light blocked, depends on the type and tint of the film you select.

Window film will adhere to all glass and will have varying degrees of results depending on your situation. We offer free consultations to discuss your specific needs, but in nearly every case the answer is yes.

We can apply film to glass front doors, French doors, skylights, high-rise hotels and office buildings, dual pane windows, tempered glass windows and more.

How long does installation take?

Installations will vary in time. For example, four sliding glass doors using a 2 ml sun control product can take as little as three hours. Removal of existing film, smaller windows and excessive calking from the glass manufacturer will add to the installation time.


Residential installations can often be completed in a day. Larger homes may take longer, and commercial projects will require custom estimates of the time needed to complete installation. We can usually work with your schedule and adjust to fit your needs. In addition, window film can be installed either on the interior or exterior of your windows. We’ll help you determine what’s best for your needs and the type of windows of you have.
