用血泪史回答你，三层隔音玻璃是夹胶玻璃，而且是夹2层胶的，胶片厚度＞1.1mm的是没问题的，夹胶加中空纯粹瞎胡闹。另外高密度玻璃就是钢化玻璃吧

夹层玻璃是由两片或多片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，使玻璃和中间膜永久粘合为一体的复合玻璃产品。

Laminated glass is a composite glass product with two or more layers of organic polymer sandwiched or multi-layer organic polymer, after special high temperature prepressure (or vacuum pumping) and high temperature and high pressure processing.
