Comparison based on TDS data 55 verified products from standalone STEK TDS documents
Compare window tints fairly
Select films, match them by measured VLT and see which option actually rejects the most solar energy.
The main heat comparison uses TSER and SHGC. SIRR at one wavelength does not describe total solar energy.
Choose your comparison
Compares films with similar transparency instead of relying only on the number in the product name.
Choose darkness
Pick a target VLT and we select comparable films at the same darkness.
VLT shows how much visible light passes through the film. A smaller number means a darker film.
VLT 35%
Pick films
Add up to six films. Every film keeps its own color across all charts.

What do these metrics mean?
Each metric answers a different question. For heat rejection, start with TSER and SHGC.
VLT
Visible light transmission. A higher value means a brighter film and more visible light entering the cabin.
Exterior VLR
The share of visible light reflected from the exterior side.
Interior VLR
The share of visible light reflected back toward the cabin.
Solar transmittance
The share of solar energy passing directly through the glass and film. Lower is better.
Solar reflectance
The share of solar energy reflected away.
Solar absorptance
The share of solar energy absorbed by the film and glass.
IRER 780 to 2500 nm
Energy rejected across a broad infrared range. It is broader than SIRR measured at one wavelength or a narrow range.
SIRR 900 to 1000 nm
Infrared rejection across a narrow wavelength range. It must not be treated as total heat rejection.
SIRR 1400 nm
Infrared rejection at one wavelength. This value is reported only in the plus family TDS documents.
UV rejection
The share of ultraviolet radiation rejected. Most products report very similar values.
TSER
Total solar energy rejected. This is the primary metric when the question is solar and heat rejection.
SHGC
The share of solar heat admitted into the cabin. A lower value means less solar heat gain.
Shading coefficient
Heat gain through the filmed glass relative to reference glass. Lower is better, but several TDS values need verification.
Glare reduction
How much the film reduces glare from visible light. Darker films usually report a higher value.
Thickness
Film thickness as reported in the TDS. Units and included layers are not always directly comparable.
How to compare the data
TDS values use STEK Automotive internal test methods. The documents do not identify the glass type, instrument or complete test setup.
The values are therefore best suited to comparison within the STEK dataset. Competitor figures require the same test method before comparison.
Standalone TDS documents are the primary source for technical values. Rounded or conflicting sales-deck figures are not used for ranking.
Suspect fields are visibly flagged and excluded from winner calculations for that metric.
