信封建筑在Va与灰泥
Roger Rogers.|Posted inEnergy Efficiency and Durabilityon
正在考虑ICF，具有传统的灰泥，但VA中的绩效比率可能不是理想的。现在考虑2×6高级框架，例如http://www.buildingscience.com/documents/information-sheets/high-r-value-wall-assemblies/high-r-wall-02-advanced-frame-wall-colstruction?topic=resources/high-r-价值
通过这种方法，我们正在考虑玻璃纤维，墙壁，1“陶氏SIS外部。仍然在外面做三道菜灰泥。
I’d really like to increase the exterior insulation, but not sure how difficult that is considering the stucco, and needing attachment points for the wire mesh/basecoat.
我已经看到了NC回答了非常相似的问题，但VA很冷，我真的很欣赏任何反馈！

罗杰，
您可以肯定将传统的灰泥安装在2秒内，3英寸或4英寸。刚性泡沫。详细信息可以在这里找到：
要安装灰泥，包括气隙。
来自文章：
“如果您正在将灰泥安装在泡沫上，这里如何创建通风雨淋差距：
* Install 1x3 or 1x4 vertical strapping on top of the foam, screwed through the foam into the studs.
*将纸张背衬金属板条固定在捆扎，并进行三层涂层灰泥的标准安装。
如果您的本地构建检查员提出有关您计划使用的螺丝的数量和大小的问题来固定您的1x4捆绑，您可能需要获得工程师来查看您的详细信息。只要你有工程师的邮票，你当地的建筑部门应该很开心。“

Rodger,
The perm rating of Structural Insulated Sheathing (SIS) is a bit scary.
来自Dow的网站：
如ASTM E96测试，步骤A，SISOFOAM™SIS™牌结构绝缘护套的烫发额定值约为0.03倍。
@Martin：谢谢你的答案！我已经审查了'安装灰泥右...'文章，以某种方式错过了那段。此外，欣赏紧固毛刺条的连接。
@Brett: I also just found that the cost of Dow SIS is a bit scary too. Since I'd prefer to go with > 2" of exterior insulation, do you have a recommendation about which type of rigid foam to use? I'd really like to achieve > R30, but stay fairly cost conscious.
@Martin：我的灰泥家伙担心将电线网连接到24“oc毛茸茸条带（因为计划外墙框架为2x6 @ 24”OC）;它们相距太远了。我倾向于同意！他通常至少每12个附加点。这通常如何处理？
罗杰，
我不确定别人做了什么。但它不应该难以安装毛茸茸的条带12- in。在中心，如果这就是他想要的话。只是金钱和时间。
罗杰，install the strapping horizontally. Not as good for drainage, but still effective as a capillary break.
我们在灰泥后面使用的垫圈的非金属蜘蛛车床每种方式都需要6英寸的紧固时间表。这就是我通常在电线车上看到的东西。当您涂上底层时，我将在整个地方蹦蹦跳跳。如果您不想使用OSB，您可以使用胶合板或木板。只要记住灰泥是一个系统，它需要在胶带包装或泡沫的顶部下湿熨斗和扩展关节和至少两层焦油纸。（当湿底漆击中它并在基板前面产生空气空间时，它皱起了皱纹）
if you want to do foam under the lathe you just need longer staples or screws. I know we can get 16 gauge galvanized 1" crown roofing staples in 1 3/4" length and i also keep the 1 3/4" X 1/2" crown galvanized sheathing staples but they don't seem as rugged as the 1" crown so I'd stick with the wider ones fro side wall over 1" foam.
ABC supply has some awesome deals on screws and they sell the R-12 Hunter-panel 2" polyiso at $26 per 4x8 sheet. it's nasty stuff to work with and you have to water proof it because it's intended as a rubber roofing substrate but a great value if you can get the details right. Just cause you don't like what you see at Home Depot doesn't mean that you can't find a way to giterdunn if you don't mind digging a little.
I found that my question had already been asked here://m.etiketa4.com/community/forum/green-building-techniques/17635/stucco-lath-over-4-foam.
The New Mexico related answer seems sensible, which is to say: you don't put traditional/three-course stucco over 4" of exterior foam. My hunch is the NM code is logical, since hanging lots of weight on protruding screws is a bit concerning.
I'm considering double-wall construction, to get the R value, plus have a more traditional exterior sheathing. Thing is, I really like the concept of 'exsulation', since it solves many of the thermal bridging issues.
有没有人有过Dow SIS的经验？他们声称它可以采取三层涂层灰泥表面处理。是否需要进一步加强才能进行丝网附件？这可能会给我一个小的外部绝缘，用于热休息，但没有灰泥悬挂在远离护套的情况下。
还,拖一点,对不起!——会advisable to do: Sheetrock | BIB | closed-cell spray | Dow SIS | stucco layers? Would in-wall moisture/mold be a problem if the stucco application is done correctly, ie. is this set of layers a no-no?
