前言

根据原北京市质量技术监督局《关于印发2018年北京市地方标准制修订项目计划的通知》（京

质监发[2018]20号）的要求。规程编制组经广泛调查研究，认真总结实践经验，并在广泛征求意

见的基础上，对《无机纤维喷涂工程技术规程》DB11/T941-2012进行了修订。

本规程的主要技术内容是：1.总则；2.术语；3.基本规定；4.性能要求；5.构造；6.施工；7.

质量验收。

本规程修订的主要技术内容是：

1.增加了北京市居住建筑和公共建筑节能设计指标要求；

2.在非透明幕墙构造中增加了隔汽层；

3.增加了吸声和隔声的要求；

4.调整了原材料和喷涂层的验收指标；

5.调整了无机纤维喷涂施工工艺和验收检验批。

本规程由北京市住房和城乡建设委员会、北京市市场监督管理局共同负责管理，北京市住房

和城乡建设委员会归口并组织实施，北京城建科技促进会负责本规程技术内容的解释。执行过程

中如有意见或建议，请寄送至北京城建科技促进会（地址：北京市西城区广莲路1号北京建工大

厦A座907室；邮编：100055；邮箱：hxjcgzb@163.com；电话：63989081）。
