Unverified87% confidenceCautionTime unknown
推拉窗因搭接结构存在缝隙，隔音天生弱于平开窗，实测同配置下推拉窗隔音约低5-8分贝；临主干道需隔音时应选5+12A+5或以上中空玻璃并加装毛条+胶条双密封，隔音要求高（≥35dB）应直接放弃普通推拉窗

Unverified隔音效果排序为：固定窗 > 平开窗 > 推拉窗；推拉窗因上下轨道有缝隙气密性差，同等玻璃配置下比平开窗隔音低约5-8dB，追求安静首选平开窗84% similarUnverified窗帘隔音主要靠克重与褶皱空气层，克重≥350g/㎡且褶皱倍数(布料宽/窗宽)≥2.0才有明显降噪，实测仅降3-8分贝，无法替代隔音窗82% similarUnverified隔音窗真正决定隔音效果的是气密性等级（需达到国标8级）+开启方式，而非单纯玻璃层数。平开窗气密性远优于推拉窗，同配置下平开比推拉隔音高5-8dB82% similarUnverified想兼顾隔音需选克重≥350g/㎡的厚重绒布或多层复合布，配合宽于窗框30cm、落地超出窗台20cm以上安装，仅靠窗帘隔音效果有限（约降3-8分贝），临街强噪音仍需搭配隔音窗82% similarUnverified窗帘的隔音主要靠克重和褶皱空气层，克重≥250g/㎡且褶皱倍数（褶皱比）达到2.0以上才有明显吸音效果；单纯遮光布对高频噪音只有3-8分贝衰减，临街隔音应优先换双层玻璃而非依赖窗帘82% similar
