《EN1279-1“建筑用玻璃-絕緣玻璃裝置-第1部分：概要、系統描述、替換規則、公差和外觀質量》的內容描述了絕緣玻璃裝置的定義，適用的規則、它們的光學和視覺質量標準及尺寸公差，及對已有系統適用的替代規范。此標準規范的出臺，使絕緣玻璃裝置滿足使用者的需要，并通過在外觀、節能、降噪和安全參數等方面統一標準而確保標準的穩定性。

其次，《EN1279-5“建筑用玻璃-絕緣玻璃裝置-第5部分：產品標準》確立了建筑用絕緣玻璃裝置的產品標準。該標準是由歐洲委員會和歐洲自由貿易協會（EFTA）授權CEN編寫。如果EN 1279-5可以在歐洲聯盟官方期刊(OJEU.)中根據（EU）第305/2011號條例被引用，它就很可能成為功能性聲明書(DoP)和歐標認證的基礎，也就是支撐EU305/2011 條例的協調標準。EN1279-5對絕緣玻璃裝置性能標準做了規定，包括抗火性、耐火性、防彈性和防爆性，以及防噪和防熱方面的性能。

最后，EN1279-2，EN1279-3，EN1279-4涉及以下方面的檢測方法與具體要求，包括（1）防潮（2）氣體泄漏率和氣體濃度公差（3）絕緣玻璃裝置的邊緣密封和插入的安裝物的物理屬性。

EN1279系列是由CEN技術委員會129制定的，其技術秘書處由比利時標準化機構NBN管轄。

TheEN 1279 series was developed by CEN/TC129 and published on 25 July 2018. The standards included cover the requirements for insulating glass units. Insulating glass units offer thermal and sound insulation, and therefore they are widely used in a lot of commercial and residential building: their main use consists of installations in windows, doors, curtain walling, and bonded glazing for doors, windows and curtain walling, roofs and partitions.

EN 1279-1 ‘Glass in Building - Insulating glass units - Part 1: Generalities, system description, rules for substitution, tolerances and visual quality’ provides definitions for insulating glass units and covers the rules for system descriptions, their optical and visual quality and dimensional tolerances, and sets the substitution rules based on an existing system description. The achievement of this standard’s requirements indicates that insulating glass units fulfil the needs for intended use and ensures, by means of the evaluation of conformity, that visual, energetic, acoustic, and safety parameters do not change significantly over time.
