R Silver 20i Heat Reflective Window Film | Rejects 79% Infrared Energy | 18% Visible Light Transmission | Blocks 99% UV | Silver Color

Avery Dennison’s R Silver 20i Reflective Window film is designed with commercial projects in mind. While offering an attractive silver appearance, it offers high energy savings rejecting 79% of infrared energy (how most heat is transmitted in the atmosphere) while offering a glare reduction of 80% and only allowing 18% of visible light to transmit through.

The R Silver 20i is an ideal solution solution for an affordable energy-saving project where reducing energy costs and maintaining an attractive look are ideal.

The R Silver 20i is an easy wet application to the interior side of the window.  Please see Application tab for detailed application instructions, our Video tab and Cleaning tab for additional insights.

Available in 25′, 50′, 75′ & 100′ long increments, it also has available widths of 36″, 48″, 60″ & 72″. To save you time cutting film, custom widths cut to order are available.

How to Measure

Determining the amount of window film needed to cover your windows is not as difficult as one would imagine. Just follow these straightforward steps to easily measure your windows and determine the quantity needed.

Measuring Your Glass

Note: Measure width in INCHES and length in FEET (divide number of inches by 12 to convert to feet.)

  1. Measure only glass area of window, not entire window frame.
  2. First measure your glass from left to right in INCHES. This is your required width. (This width corresponds with the “Roll Width” listed on each product page.)
  3. Then Measure your glass from top to bottom in FEET. This will be your required length. (This length corresponds with “Total Length (Feet)” on each product page.)
  4. Be sure to write these measurements down. We suggest adding 1 inch in each direction to your measurements. This allows room for error and cutting during your installation. The slight overlap will allow you to carefully cut the film to the edge of your glass, custom fitting your window.
  5. Repeat measuring for each window.
  6. Add together the lengths for all of your windows to come up with Total Length of film required in FEET.

Ordering Your Window Film

  1. Navigate to the page of the desired film. Select the width in INCHES that best fits your windows as determined by the previous steps.
  2. Your Total Length measurement (length of all windows combined in FEET) equals the quantity needed in feet of your chosen film. Ships as one continuous roll
