一些延伸气候区和阁楼通风配置事项。In most of the US you could staple up housewrap (Tyvek, et al) on the underside of the joists, then use 1x4 cross-strapping perpendicular to the joists 16" o.c. to support the housewrap to which the gypsum board could later be fastened. The strapping is necessary to limit the amount of sag, which would otherwise make it difficult to hang the gypsum.

在美国气候区7＆更高（或在第6区，如果没有非常好的阁楼通风），使用聚片（加拿大式）可以更好地限制水分可以进入阁楼的速度蒸汽扩散。
要么将薄薄的薄片作为空调，搭接和绑定所有接缝和钉，都很重要
使用Pan-Head螺钉或铃声钉（2个每个托梁交叉点）来挂1x4s或者它们会随着时间的推移分开。
如果你在阁楼里有机械，那就更好地（但更昂贵）与屋顶甲板上的尚未辩护的阁楼和绝缘，但这是另一个讨论。
我正在考虑一些刚性的东西，如一片3/8胶合板或银色保温板。但Tyvek可能是一个好方法。捆绑会使椽子更容易。仍然不确定我是否与击球人或吹入保温。我住在夏洛特NC，我想用泡沫，但它的贱人。谢谢拉尔夫
