How to Compare Window Film Measurements

A useful answer starts with how to compare shade-specific window film measurements.

This guide focuses on how to compare shade-specific window film measurements. The exact product, glass, coverage, installation, and current requirements still control the final decision.

• Compare VLT and TSER as separate values
• Read the wavelength range alongside each infrared rejection figure
• Ask which product and shade are included in the quote

Compare the actual figures for the exact film and shade

VLT, TSER, UV rejection, and infrared rejection are different measurements. Review current manufacturer data for the exact film and shade; do not treat one value as a complete measure of comfort.

• Compare VLT and TSER as separate values
• Read the wavelength range alongside each infrared rejection figure
• Ask which product and shade are included in the quote

Use the actual glass instead of a stock assumption

When choosing a shade, compare data for the exact product and shade in your quote. Check the test conditions and remember that published figures do not predict a specific vehicle's temperature.

Common questions

Which film measurement tells me how much heat is rejected?

TSER measures total solar energy rejected. Infrared rejection is reported separately by wavelength, so neither value should be substituted for the other.
