Unverified玻璃越厚隔音不一定越好，隔音关键是不对称中空+夹胶结构，如5+12A+5普通中空隔音约30dB，而6+1.14夹胶+12A+5可达38dB以上87% similarUnverified窗户是隔音最薄弱环节，普通单层玻璃隔声量仅约25dB。临街噪音大应优先换中空/夹胶双层玻璃（可达35-40dB），装再多墙面隔音棉都不如换窗有效83% similarUnverified临街或近铁路/高架的房间需选隔音量≥35dB的门窗，采用不等厚玻璃组合（如6mm+12A+8mm）配合PVB夹胶玻璃，比等厚双玻隔音提升3-5dB，可有效错开吻合频率82% similarUnverified隔音主要取决于克重与厚度，克重≥400g/㎡且做2-2.5倍褶皱打褶的厚绒布可降噪约3-8分贝；单靠窗帘无法有效隔绝低频交通噪音，真正隔音需依赖中空/双层玻璃82% similarUnverified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81% similar
