What does IRER explain that simple sunfilm demos often miss?

A common customer problem is trusting one quick heat demo or one strong-sounding number. But IRER is broader. It refers to infrared energy rejected across 780–2500 nm, including reradiated absorbed energy. In simple words, it looks at more of the heat story than one narrow reading can show. That is why one fast demo should never decide a serious comparison. #RajuCars #3MSholinganallur
