Ceramic Tint Specifications: IR, TSER, and UV

A useful spec sheet shows more than one number.

IR rejection, TSER, UV protection, and visible-light transmission describe different parts of a film's performance. Read them together, and confirm the tested glass and shade before using the numbers to choose a product.

• Record the exact film, shade, and test glass
• Do not compare an IR headline with a TSER result as if they are identical
• Use visible-light transmission to keep the appearance and legal discussion grounded

IR, TSER, and UV answer different questions

IR rejection concerns part of the infrared spectrum. TSER is a broader total-solar measurement. UV protection describes ultraviolet transmission. Visible-light transmission describes brightness. None of these numbers alone predicts exactly how a particular vehicle cabin will feel.

• Record the exact film, shade, and test glass
• Do not compare an IR headline with a TSER result as if they are identical
• Use visible-light transmission to keep the appearance and legal discussion grounded

Why test conditions change the comparison

A film tested on one pane of glass at one shade may not produce the same result on a different factory glass package. Ask for the full sheet and compare measurements made under similar conditions.

Common questions

What ceramic tint number matters most?

There is no single best number. Review IR, TSER, UV, visible-light transmission, glass, test method, and warranty together.
