夹层玻璃是由两片或多片玻璃，之间夹了一层或多层有机聚合物中间膜，经过特殊的高温预压（或抽真空）及高温高压工艺处理后，使玻璃和中间膜粘合为一体的复合玻璃产品。

夹层玻璃和夹层安全玻璃上加贴CE标志不但可以证明其产品符合建筑产品指令（CPR 305/2011/EU）及其相关标准（欧洲协调标准EN 14449）规定的安全，环保，卫生和消费者保护。而且可以合理规避贸易技术壁垒，在欧洲市场自由销售并打开其他国际市场。

夹层玻璃CE认证标准：EN14449

EN 14449:Glass in building - Laminated glass and laminated safety glass - Evaluation of conformity/Product standard

EN 14449:建筑用玻璃.夹层玻璃和夹层安全玻璃.合格评价/产品标准

本欧洲标准涵盖了建筑物用夹层玻璃和夹层安全玻璃的合格评定和工厂生产控制
