What is Window film?

Window film is typically made of polyester film in various thickness and finishes.
How Does Window Film Work? 

Window film can be applied to both the interior and exterior side of the windows. You can enjoy benefits including lower energy costs, safety and security protection.
What kind of maintenance is required for window film? 

Cleaning any of our window films is very easy.

  • Always clean our window films with a soapy water and a soft cloth or a clean synthetic sponge or soft squeegee.
  • A simple cleaning solution for window films is one teaspoon of liquid dish wash detergent added to 32 ounces of tap water.  
  • Do not use any liquid dish wash detergent that contains a degreaser.  
  • Never use cleaning products that contain ammonia or vinegar as a cleaning solution.
  • Always use soft cleaning materials to dry your window films after cleaning.  
  • Do not use brushes or any abrasive scrubbing sponge products when cleaning your film.  
  • Do not clean your window films sooner than 30 days after your installation.
How long will film last? 

Window film can last well over 10 years if installed properly.
How Much Can It Save Me In Energy Consumption? 

This can depend on the region you live in. Typically window film can lower utilities bills in excess of 10%.
What Are The Benefits of Window Film? 

Benefits include Safety, Security, US Protection, Fade Protection, Storm Protection, Heat Reduction, Bomb Blast protection. Visit our Window Film Benefits page to learn more.

Solar Energy Technical Definitions

Tinting Terms Simplified

Visible Light Transmission (VLT)

The % of total visible light that passes through a glazing system.
Visible Light Reflectance (VLR)

The % of total visible light that is reflected by a glazing system.
Total Solar Absorption 

The % of incident solar radiation that directly passes through a glazing system.
Total Solar Transmittance (TST)

The % of incident solar radiation that directly passes through a glazing system.
Total Solar Reflectance (TSR)

The percent of incident solar radiation that is reflected by a glazing system.
Ultraviolet (UV) Radiation Rejection

The % of total UV light that is prevented from passing through a glazing system.
Total Solar Energy Rejection (TSER)

The percent of total solar energy (heat) rejected by a glazing system.

(It equals the solar reflectance plus the part of solar absorption which is re-radiated outward).
Shading Coefficient (SC)

The ratio of solar heat gain passing through a glazing system to the solar heat gain that occurs under the same conditions if the window were made of clear, unshaded double strength window glass.

(The lower the number, the better solar shading qualities of the glazing system).
U-Value

The amount of conductive heat energy (BTU’s) transferred through one square foot of a specific glazing system for each 1°F temperature difference between the indoor and outdoor air. The overall coefficient 
of heat transfer by conduction equals the reciprocal of R-Value (U=1/R).

The lower the U-Value, the better insulating qualities of the glazing system.
