We briefly explain why it’s best to use the TSER (Total Solar Energy Rejection) when quoting a window films heat rejection performance over infrared rejection.
Australian sunlight comprises approximately of 53% infrared energy, 44% visible light and 3% UV.
So 95% IR rejection doesn’t mean 95% heat is blocked, it means only 95% of the 53% is blocked.
