Plaster wall replacement on a 1890’s brick home
感谢您创建如此出色的网站，作为我的第一次房主，这对我来说是如此的帮助。
I recently purchased an old brick 2 flat in chicago. The interior walls are all plaster over lath and in good condition, with the exception of one room. A previous owner put up wood paneling in the 1960’s in one of the bedrooms. The paneling is backed with some sort of felt paper that I assume is used as a vapor/moisture barrier and this was put right over the old plaster. Well the other day I discovered a small exterior window that I hadn’t noticed previously. The window was in very bad shape and needed to be replaced. It turns out that they paneled over the window. I took the paneling off the walls and the plaster behind it just crumbled and fell to the ground. I’m assuming the paneling and felt didn’t allow the walls to breathe which caused the deterioration. My initial idea was to put in some rigid foam insulation, possibly with a small air gap between the bricks and then add drywall. I’ve been seeing in some of the questions on here that that may not be a great idea. The second Idea I had was to put some cement board directly over the lath as some sort of plaster substitute, I figure it is moisture resistant and may have a similar breathability to plaster. I have never actually heard of this being done so I’m hesitant to go down that road. I’ve seen on the website that the best solution would be to insulate the exterior of the wall and put up some siding or something. This however is not possible because the house was built directly on the property line so anything I add to the brick would be encroaching on my neighbors property. Any ideas for solutions? Again it is just one room, and the wall needing replacement is about 16 feet wide by 9 feet tall.
谢谢！

I've fixed a couple of older cracked plaster walls by covering it with 1/4" drywall. If you have larger baseboards, you can drop the drywall right on to the top edge without removing them. This is in an uninsulated double brick house. No issues even in a bathroom.
如果您想要更多的隔热材料，假设现有的3/4英寸绑带砖在砖上，则可以在墙上用2x3在平面和喷雾泡沫上交叉皮带。喷雾泡沫的2英寸可带来不错的R值提升，并且通常不会导致太多砖块麻烦。
I would stay away from non SPF solutions.
您可以包括任何照片吗？
我假设您的建筑物具有结构性砖墙组件，而不是砖贴面组件？
很难提供良好的指导或建议，而没有更多有关外部壁的配置的信息，从外部到内部。

Here are some pics. This is not a brick veneer, it’s at least 2 bricks deep with about a 2” furring strip holding up the lath and plaster
嘿，得到你的名字真是太好了...
The photos are difficult to read. It looks like you have a double brick wall and the wood lath is fastened to the brick with nothing in between. Is that correct?
It’s Chris,
Yes it’s double brick with some furring strips and lath.
Basically I’m just looking for the best way to cover these walls that won’t ultimately damage the brick
克里斯，
This is a classic case of chicken or the egg. Did the plaster go bad because of the paneling or the paneling was put on because the plaster was in bad shape. I would bet it is the 2nd case.
除了水和冻结外，没有什么会损坏砖块。到达那里的唯一方法是添加过多的隔热材料而不能很好地控制水分。
如果您没有绝缘的墙壁，则几乎没有机会损坏砖。就像我之前说的那样，您可以用1/4英寸的石膏墙修补。图片中的墙壁状状态不好，整墙都覆盖着1/4英寸的干墙，大部分都粘在了石膏板上。在那里呆了6年没有问题。
如果您缺少较大的石膏部分，则最好用一些石膏板+一层Durabond填充，否则在这些区域将墙壁“柔软”。
