防火窗

F7 · 2 门型

防火窗封闭防火分区线上那些必须保持通透的部位:面对防火间距的外墙、楼梯间围护、走廊隔断与机房观察口。固定式与开启式都可做,钢质门框配认证防火玻璃,并与同一立面上的门做同色配套。窗的性能取决于整樘构造——框、玻璃、密封与固定——任何一环弱,整樘就弱。开启式增加了通风功能,也增加了一套必须可靠闭合的机构,因此闭合做法要在生产前定清楚。

选型要点

  • 把窗当成一整樘:框、玻璃、密封与固定一起指定,不要分开采购。
  • 开启式需要与门框一起验证的闭合机构,要问清火警时如何保证关闭到位。
  • 窗的表面处理要与相邻门一致,否则本来干净的立面会显得像补丁。
  • 外墙立面要单独明确水密做法,不能与防火密封混为一谈。

常见问题

Can fire windows be openable?
Yes. Openable types add a controlled closing mechanism, which is specified with the frame rather than added on site.
Do windows need the same rating as the doors?
The rating follows the compartment requirement at that location, which is not always identical to the adjacent door. It is read from the fire strategy.
Is the glass laminated?
The glass build-up depends on the rating class and the required pane size, and is confirmed for each configuration.
Can these be used in a curtain wall?
Interface with a curtain wall is a detail that needs to be agreed between the two systems. Send the interface drawing at enquiry stage.
