Unverified深色遮光布本身遮光更高但吸热，西晒房间选浅色银涂层布（表面浅色反热、背面黑丝遮光）比纯深色布室温可低2-3度90% similarUnverified隔热需求下，浅色/带白色底衬的遮光布反射阳光效果优于深色，西晒房间选浅色三层复合遮光布可降低室内温度2-3℃；纯深色涂层布吸热反而更烫88% similarUnverified遮光同时想隔热降温应关注布料背面反射层：银色/铝膜涂层反射红外线隔热效果最好，夏季西晒房可降低窗边温度3-5℃，但银色涂层从室外看反光明显且不美观，可选表布深色+背面浅涂层的复合款88% similarUnverified遮阳棚面料的遮光率与UPF不完全等同：深色/致密织物遮光好但吸热升温快，浅色反光面料表面温度更低，夏季直射环境优选浅色或带银色反光涂层的外层面料86% similarUnverified深色面料（黑/深灰）挡光和防晒性能通常优于浅色，但吸热更明显；夏季高温建议选外浅内深或带反光涂层的双层结构，兼顾遮光与隔热86% similar
