Some tints protect against infrared between 1000 nm and 2500 nm (e.g., 3M™ Ceramic IR Films), while some don't (e.g., 3M™ Crystalline Automotive Window Films) but still claim to protect against 97% of heat-producing infrared.
What's the point of having infrared protection between 1000 nm and 2500 nm when tinting car windows?
