我正在寻找绝缘的一个1894年维多利亚位于彭布罗克，安大略省6气候区阁楼。拱腹是没有通风的，它们是由油漆舌和凹槽木构造的山墙脊是通风的，平屋顶上有一个最大的通风口，平屋顶周围有一些通风口。炮塔屋顶区域没有通风，但通过大约2 ' × 1 '的空隙与主阁楼区域连接。目前主阁楼空间中约有3-4″的纤维素，三楼斜顶的椽子都填充了纤维素;然而，这些年来，纤维素已经沉淀下来了。三个浴室风扇通过平屋顶通风到室外。自然地，在冬天，尤其是在山谷里，这处房产有冰的问题。我计划今年夏天更新绝缘，我正在寻求建议。我还打算在膝盖后面进行隔热。一个膝部有一个进入面板，但它是相当紧。 The other kneewalls are in finished spaces. The house is a student rental, so one attic bedroom is vacant at the moment, so I was planning to insulate the kneewalls in this vacant bedroom and in the bathroom where the kneewall access panel is located. I’ve read the article here – https://www.finehomebuilding.com/2012/09/06/two-ways-to-insulate-attic-kneewalls. I’ve also read Martin’s response to comment #55 here – //m.etiketa4.com/article/lstibureks-rules-for-venting-roofs. I’d appreciate some recommendations given that I currently have ice damning issues. My original thoughts are to do 1.5″ of ccsf and cellulose in the attic to provide a total of R70 and top up the rafters of the sloped ceilings with cellulose. I’m not sure what approach I should take for the kneewalls yet.

提前谢谢。
