Unverified边缘和顶部漏光是遮光帘的主要失败点，即使布料100%遮光，穿孔式（打孔帘）顶部会从孔洞漏光，褶皱帘需搭配天花板顶装+两侧回墙或加装遮光挡边条才能实现全暗环境84% similarUnverified顶部漏光是遮光失败的主因，罗马杆安装因帘布与墙面有缝隙易顶部透光，追求极致遮光应选轨道+封闭式帘头（或加装遮光帘幔box），或让窗帘紧贴天花板安装84% similarUnverified开合方式中，罗马杆安装简单外露美观但两端布料重叠会漏光，导轨（窗帘轨）藏在窗帘盒里遮光好、能贴墙拉到底但需吊顶预留，做全遮光卧室应优先选导轨83% similarUnverified涂层遮光布不建议用于飘窗内嵌或需要频繁开合的窗户，涂层长期折叠摩擦会开裂脱落导致遮光率骤降，此类场景应选提花全遮光布或蜂巢帘82% similarUnverified追求便捷全黑且窗户尺寸标准（宽度<1.5m）时，蜂巢帘/卷帘的侧封天轨方案比布艺帘漏光更少、更省空间，但蜂巢帘不可水洗只能吸尘、损坏后难维修79% similar
