墙体有外保温时外窗的安装方法研究

安装外窗采用企口后塞安装法,可避免外窗框受损、变形,有效防治渗漏,减少窗洞口与外窗框实际间隙的离散,窗框的室外洞口抹企口采用保温砂浆,可防止室内结露;建议外窗设计洞口与外窗框的理论间隙增至25～30 mm。

RESEARCH ON EXTERIOR WINDOW INTALLATION METHODS ON WALL WITH EXTERNAL INSULATION

In this article, it is studied that when using post-installed methods to install exterior window, it can avoid outside window frame damage and distortion, it can also prevents and controls the leakage effectively and reduce the longlost of the actual interspace between the window hole and window frame. Using thermal insulating mortar in the outside cave of the window frame can prevent forming dew; It is suggested that the theory interspace between the designed exterior window cave and exterior frame should be increased to 25-30 mm.
