Unverified隔热优先选红外线阻隔率（IR）≥80%、总太阳能阻隔率（TSER）≥50%的磁控溅射金属膜；廉价染色膜只降可见光不隔热，晒久了退色发紫87% similarUnverified隔热防晒膜关注红外线阻隔率（IRR）而非单纯遮光：IRR≥90%才有明显降温效果，紫外线阻隔率（UVR）几乎所有品牌都能做到99%，不构成区分度83% similarUnverified隔热为主要诉求（西晒房/顶楼）应看红外线阻隔率≥85%和紫外线阻隔率≥99%，而非单看遮光率；金属镀层膜隔热优于纯染色膜，但可能干扰手机/WiFi信号76% similarUnverified静电膜的隔热效果主要靠遮光遮挡而非物理隔热，红外线阻隔率（IR）真正决定车内降温，选购时应关注IR≥80%的产品，仅标注UV阻隔而不标IR的多为普通遮光片75% similarUnverified浅色（白/浅灰）防晒手套体感更凉但紫外线阻隔率通常低于深色；深色（黑/藏青）吸热明显但阻隔率更高，追求防晒效果优先深色+高UPF组合73% similar
