Unverified85% confidenceDecision RuleTime unknown
尺寸定制注意区分内装（装窗洞内）和外装（装墙面/窗框上方）：内装要精确测量窗洞并预留1-2cm安装间隙，测大了装不进；遮光需求高应选外装并两侧各多出5-8cm挡光

Unverified尺寸定制需明确'内装'还是'外装'：内装（装窗框内）需减去左右各1-1.5cm的运行间隙，否则卷帘会卡住；外装（装窗框外墙面）宽度需比窗洞左右各多出5-10cm以减少漏光90% similarUnverified定制尺寸测量：内嵌安装（装在窗洞内）宽度应减1-2cm留缝，会牺牲侧边遮光；外挂安装（装在墙面/窗框外）宽度每边加宽10-15cm、上方加高10-20cm才能有效遮挡漏光，全遮光务必选外挂89% similarUnverified定制尺寸需注意：内嵌款成品宽度通常比测量窗内宽小10-15mm留出运行间隙，因此边缘会有漏光，对遮光敏感区域应改外装或加宽外装尺寸覆盖窗框88% similarUnverified安装方式分内嵌（窗框内侧）和外装（墙面或窗框外），内嵌美观但四周会有约1cm漏光缝隙，追求全遮光应选外装并让帘体两侧超出窗框5cm以上87% similarUnverified测量内嵌安装尺寸时需在窗框内上中下三处分别量宽度取最小值，并减2-4mm留活动间隙；外装则按需遮盖面积加宽，宁大勿小以保证遮光85% similar
