在6区的商店绝缘材料
我在6区有一家商店,上面有2×6的墙壁上覆盖了OSB,然后是金属壁板(我看不到或告诉的是没有建筑包装)。
I want to insulate the walls. I am looking at different options. The shop will not be heated full time so I don’t want to spend a fortune but when in it want it comfortable.
I am looking at just 2″ of closed cell foam by itself. (The garage in our new house has 2″ in the wall and 6″ in the roof and is working well.)
OR
我想我可以做2英寸的闭孔泡沫,然后可以做R13棒,对于适当的泡沫/玻璃纤维进行水分控制,这应该是正确的,但对于商店来说,这应该很昂贵。
OR
我对仅使用R19 Batts更感兴趣。如果我在OSB的内部放置蒸气屏障,然后将BATT放在上面?
其中哪一个可用于防潮?瓦特将是最便宜的。
阁楼是未放气的所以我的计划只有4”of closed cell foam sprayed on the bottom of the roof decking. Then later I will add a drywall on the ceiling and walls
Thanks

答复
我会给你的帖子一个颠簸。OSB是护套(外部)吗?你现在在哪里?
韦斯特克利夫(Westcliffe)在丹佛(Denver)以南约3小时内合作。
OSB位于钢壁板下方的外部。
我会发布答复,但我不是专家。也许将此线程碰到列表的顶部会增加一些意见。
您可以在墙壁中喷洒2英寸的闭孔(HFO吹式剂对环境更适合环境),这将有助于空气密封内部。但是我也认为您想在其余的腔体中安装玻璃纤维棒,以使泡沫的内表面在冬季保持足够温暖。否则,OSB可能会积聚过多的水分。
如果您想类似地将屋顶“闪烁和瓦特”,则需要在护套上安装R-25的闭合牢房,然后用玻璃纤维或其他可渗透的绝缘材料弥补平衡。
有关更多信息,请参见本文://m.etiketa4.com/article/flash-and-batt-usnulation。请注意,马丁强调,闪光灯和巴特在像您这样的寒冷气候下风险更大。我冒险说,如果您只做闪光灯,这可能会更加风险。
也就是说,我更关心您房屋中绝缘的子代码水平。是否有墙壁或天花板上的任何区域可以在护套中插入水分探针 - 只是在安全的一侧?我对评估屋顶岭和房屋北侧的状况特别感兴趣。
For an unvented roof the closed cell foam is probably the safest route but the drywall is a good idea to protect it right away. Codes require a thermal or ignition barrier to cover almost all types of foam plastic and drywall is the cheapest way to go.
Consider what moisture sources will be present (or not present) within the shop. Your walls would be okay with just batts and an interior air barrier, assuming you're not putting a swimming pool or a steam sauna in this shop. Air barrier could be sealed poly but personally I would suggest plywood or osb with taped seams for more drying capability in spring and summer.
同样,由于缺乏建筑纸或其他天气电阻屏障的缺乏。如果首先无法正确管理散装水,则添加绝缘材料非常有风险。绝缘材料大大降低了外护套的干燥能力...如果它可以从腐烂中节省腐烂,则值得暂时去除壁板。
