通常建商所附的金屬大門均以達到防火與防竊等基本功能。至於隔音或氣密等要求則較為缺乏。標準隔音門的隔音品質與價格成正比,其隔音等級如經政府機構相關部門測試,隔音數據均值達到45dB以上才屬於隔音門,其價格至少自4萬多元以上起跳。消費者如購買時應該查詢該該隔音門的隔音測試書面報告是否公開供消費者參考?少數商家不願提供,僅於購買安裝後才肯出示相關資料,這對消費者有相當大的風險與不公。
究竟更換大門也是筆不小的花費,同時又有質疑其隔音品質的風險。至於如何以最經濟又有效的DIY方式加以改善就可達到最的要求?

首先應該先辨別聲音是由何處作為傳輸路徑?其方法是門外有聲音傳入家裡時,將耳朵靠近門片四周縫隙聆聽,將會發覺原來聲音是由縫隙作為路徑,金屬門片反而比較沒有聲音傳入。所以只要對症下藥即可何需因此花大錢更換整樘門?
一般金屬門都有附加門檻(其材質可能是金屬或石材等),所以應該運用專業等級隔音條材料如S773隔音條黏貼於ㄇ型門框與門檻側面,當門片關上時讓縫隙縮小至最少程度,就可發揮隔音與氣密的雙重效果,而且完成不會造成無法關上門的冏況。

S773隔音條採用超級耐候矽膠(介於華氏零下58度至450度或是攝氏零下49度至232度)軟性材質,不會因溫度變化或是長期不斷擠壓而變硬變形。三個不等長度的斜鰭特殊設計一體抽取成型,使用時經門扇的擠壓自行產生雙重氣泡包大幅降低聲音與氣流的流通,進而提升隔音與氣密效果。事前可依據該產品是否有經過國際認證的相關標準來判斷其相關功能?S773隔音條通過美國UL10C防火等級,UL1784防煙等級,ASTM E90隔音測試認證,同時俱備原廠雙面背膠使用上極為簡易,自行DIY提升金屬大門的隔音與氣密效果,不需花大錢換門!
