Infrared Rejection (IRR)

Infrared Rejection is usually quoted across either the full near-infrared band (780–2500 nm) or a peak-IR window (often 950–1000 nm where solar heat is strongest). Different manufacturers measure on different bands — always check the spec sheet before comparing brands.

Infratint Platinum99 hits up to 99% IRR at peak wavelengths and is engineered specifically for tropical conditions where IR represents more than half of the solar energy hitting the windscreen. Higher IRR translates directly to a cooler dashboard, lower aircon load, and less fatigue on long drives.

IRR is not the same as total solar energy rejection. A film can have 95% IRR but reject only 50% of total solar energy if it does not block enough visible-light heat and UV. For the most honest comparison, ask for both numbers.
