空气密封泳道天花板
Danila Apas|Posted inEnergy Efficiency and Durabilityon
我正在努力改造我们新购买的1908家家,并在所有方面提高效率。我所面临的一个大项目之一是天花板和阁楼。取下一些丑陋的下降天花板后,我面对原来的舌头和凹槽舷板。除了几个部分需要更换的若干部分,而且有点下垂,天花板看起来很棒。然而,我确定它是一个直接进入阁楼和世界的绝对漩涡。目前,上述托梁用纤维素与托梁和偶尔的玻璃纤维毡绝缘。
我的问题是:在保留抛船的外观时,空气上空飞机的最佳方式是什么?我用干墙覆盖它,但我的妻子坚持认为我们试图制作抛船工作。
Ideas I have had:
1.取下纤维素,将泡沫板放在托梁之间。用喷雾泡沫密封边缘。
2.像特卫强去除纤维素,添加一个障碍and use Spray Foam between the joists.
2.在阁楼托梁顶部放置某种物质(胶合板?干墙)的膜,并用更多的纤维素覆盖它。
I’d appreciate any input! Thanks.

Danila,
你必须至少暂时去除现有的纤维素。如果纤维素清洁,可以重新安装它。
The best way to proceed (once the cellulose is removed) is to carefully remove the bead-board ceiling from below with a flat bar. Then install a drywall ceiling, tape the drywall, and re-install the beadboard.
一旦完成,您就可以从上面隔绝 - 与临时移除的纤维素,或用新的纤维素。
Thanks Martin.
这有点令人失望但是可以理解。真的没有好的方法可以拿下天花板,它在可能只是劈裂的地方脆弱,这将是不可用的。
在阁楼托梁顶部的干墙会像干墙一样执行类似的功能吗?特别是如果除去纤维素,则珠板和干墙之间只有气隙?
Danila,
如果您无法暂时拆下天花板板,并且您可以让您的心脏设置在保持现有板上,您可以去除纤维素;用托梁之间的纸板条保护电路板(面向阁楼)的背面;然后将喷雾聚氨酯泡沫从天花板的阁楼侧安装到纸板上。
一种或两英寸的喷雾泡沫将提供空气屏障。然后你可以用厚厚的纤维素完成绝缘作业。
The cardboard itself would be a sufficient air-barrier, as long as you sealed the edges to the joists with can-foam.
Another approach would be to use a broad-sheet housewrap and NOT cut it, but rather, to wrap the joists with it, stapling it to the sides of the joists down near the bead-board level, sealing it at the edges, and over lapping any adjacent sheets where they can be adequately taped & stapled to framing, and installing the insualtion over the result. With 8-12' wide sheets there will be far less seam leakage etc. .
但是如果有很多钉子点伸出,那将撕掉纸张货物方法,那么几英寸的开放式电池喷雾泡沫奇迹作为空气密封。你仍然需要胎圈板上方的纸板将喷雾泡沫粘在珠子板上,这将来会使珠子板的任何修复/更换更换。
Thanks for the advice, Dana and Martin.
I will peel back the cellulose and see how it looks. I am somewhat nervous about wide area spray foam because of losing the ability to change something later (and off-gassing concerns). But put over cardboard, it could be a great solution here, and off-gassing shouldn't be an issue in the attic.
Cool, I've got some work to do!
只想在这个未来看到它的旧线程上跟进这个旧线程。我最终删除了旧纤维素,并在托梁之间使用纸板填充的卷。在大多数情况下,它非常适合 - 我发现24“卷起(大多数)我的托梁。
然后我在喷雾泡沫上的闪蒸涂层上有一个承包商喷雾,然后用更多的纤维素旋转它。到目前为止,它一直在工作!
Danila,
Thanks for sharing your success story. I'm glad the job went smoothly.
