在毡纸和内部壁螺栓腔之间密封缝隙？
homeowner123| Posted inGeneral Questions在
Hi there,
我目前在奥斯汀装修房子,while I have the walls opened up from the interior, I wanted to know whether or not to caulk or use spray foam as a way to fill in the gaps between the sheathing material and the stud walls. In portions of the house there is felt paper for the areas with wood siding, and other areas there is thermo-ply for the brick walls.
我的关注与预防害虫有关，而不是能源效率和空气紧密。具体来说，我想对这些护套材料和底部窗台板之间的差距做些事情 - 我可以看到蚂蚁土墩和白蚁的污垢以及在过去几年中发现的污垢的证据。对于具有热线的区域，在螺柱框架的热ply和底部之间还夹着一层黑色塑料板。纤维素将是绝缘材料。
谢谢你的帮助，
Charlie

Charlie,
Your instinct is correct. Air sealing efforts have multiple benefits, and pest entry prevention is one of them.
因此，继续前进并空气密封。通常，可以用填缝剂将小裂缝密封，并且可以用罐装喷雾泡沫密封较大的裂缝。
Of course, there is no guarantee that mice won't chew through cured spray foam. But air sealing efforts always help.
Hi Martin,
Thank you for your prompt reply. Do I need to take into account any kind of expansion or moisture issues? I'm leaning more towards the foam because in some areas the materials are fairly loose, where the the black plastic/thermo-ply pull away from the studs and there isn't much contact.
我会记住有关老鼠的这一点，幸运的是，如果记忆对我有好处，过去没有问题。
Charlie,
Q. "Do I need to take into account any kind of expansion or moisture issues?"
答:一个high quality caulk should be flexible enough to handle normal expansion and contraction issues -- better in most cases than cured spray foam (although using spray foam to seal gaps is obviously a good idea, even if the spray foam isn't particularly flexible).
Every builder should consider moisture issues. The first question to ask is, "Am I seeing any signs of moisture accumulation or damage?"
如果这个问题的答案是肯定的，那么第二个问题是：“水分的来源是什么？”
马丁，
当我选择填缝剂并喷洒泡沫时，我会记住这一点。
就水分问题而言，过去存在屋顶泄漏，因此是白蚁的问题。除此之外，很难判断是否还有其他水分问题。In about 5-10 areas spread throughout the house, the bottom portion of the thermo-ply has either been chewed away or disentigrated, which I take it to mean there must be moisture building up in those areas, but I’m not sure of the cause.
但是我只是想确保通过填写我最初发布的接缝，我不会在某个地方的某个地方造成水分积聚。
Charlie,
需要研究损坏的热牌的原因。
Is there splashback on the bricks?
等级太高了吗？
Does the exterior grade slope toward the house?
Are the weep holes at the base of the brick veneer clogged?
在某些情况下，有墙壁部分砖和壁板，而热派是唯一的背衬材料。这些地区的壁板处于较差的状态，我认为至少在这些条件下，这可以解释受损的t-ply。[前2张照片]。我们将在今年晚些时候更换壁板和水槽，希望这会照顾很多水分问题。
坡度在某些区域看起来几英寸太高，但是即使我可以看到完整的粉底板，我仍然看到T-Ply中的孔。哭泣的孔现在看起来还不错，但在某个时候可能会被蚂蚁丘堵塞。有飞溅的问题，导致侧壁腐烂，但在这些区域没有T-ply，毛毡纸看起来状况良好。
The grade does not appear to be sloping towards the house.
第三张照片是损坏的t-ply，似乎没有用一些建议来解释，而且我看不到土墩。在我看到污垢丘的地方，我假设受损的t-ply是由于哭泣孔的蚂蚁/堵塞所致。
If the windows were not properly sealed, could water be collecting at the bottom of these studs and be causing the damage to the t-ply? [fourth photo, hole in both black plastic and t-ply]
Thank you again for all your help so far.
Instead of using thermo-ply to replace to damaged sections (and because there might still be moisture issues), could I use extruded polystyrene instead? I'm wondering if it will be too thick to slide in between the brick an the bottom plate. If it does fit, could I just wedge it between the undamaged t-ply and the studs?
Charlie,
我不愿通过互联网提供建议。需要进行现场访问才能弄清楚为什么要腐烂。
The usual order of business would be:
1. Determine the source of the moisture that caused the rot.
2. Remedy the problem that allowed the moisture to accumulate.
3. Remove all rotten components and install new materials.
In general, the ThermoPly should be fastened directly to the exterior side of the studs and bottom plate, so I'm not sure why you are thinking of "wedging it [the XPS] between the undamaged t-ply and the studs."
I understand that a physical assessment would be better. Who would I consult with to check on those issues, a building inspector? As of now, I'm still thinking the issues are related to deteriorated siding, windows that don't have much in terms of flashing, and perhaps old ant mounds. Both siding and windows will have to be replaced later in the year, or early next year, but in the meantime, we're trying to close up all the walls in order to move back in within the next two months. Originally I was planning to replace the rotted t-ply with new t-ply, but then started wondering if XPS or some other material that could withstand water could be a better option.
By wedging it, I meant some kind of adaptation of an approach to a flood-proof wall assembly as proposed by the Building Science Corporation [first attached image]

where the xps is installed in a shingle-like fashion. There, the foam runs along the complete height of the wall, but in our case, we wanted to know if it would be possible to use the existing t-ply, cut just above the deteriorated portions, and insert the foam just underneath the t-ply, using adhesive or a flashing tape to secure the foam.

我不想在墙壁上防洪水，但是直到我们能够解决水分问题之前，我希望有一种解决方案可以作为更好的水分屏障或排水平面，而我们可以进入这些区域。如果有帮助，我也可以在底板上使用一些闪烁的胶带（并用填缝/泡沫填充缝/接缝，如最初讨论的那样）。我知道这有点倒退，但是我们的时间表和预算现在有些不同步。
Charlie,
您需要找到一个当地承包商，该承包商在诊断和解决墙壁中的水上问题方面经验丰富。我希望有一种神奇的方式来告诉白痴的好承包商，但不幸的是没有。这很难。从您信任的当地人那里获得建议。
如果您要从外部工作，则可以使用任何想要的护套。当然，胶合板比热涂更耐用。在奥斯丁，只要您不安装太多的刚性泡沫，就可以安全地使用薄刚性泡沫进行护套。
If you are working from the interior (where you have brick veneer), your options for repairing sheathing rot are more limited, and you may have to try something like the approach suggested by Building Science Corp.
