Unverified隔热优先看红外线阻隔率IRR而非单纯遮光，优质金属磁控溅射膜IRR可达90%以上，而普通染色膜IRR多低于50%，遮光深但不隔热87% 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83% similarUnverified西晒/顶楼房间选红外线阻隔率≥85%且总太阳能阻隔率(TSER)≥55%的膜，降温效果才明显；仅标注紫外线阻隔率(UV)的膜对隔热基本无用83% 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78% similar
