Exterior wall insulation help
I recently replaced a window on the exterior wall of my 1960 house. The wall is half concrete, half 2×4 construction. I framed in the window with 2×6 with the intention of furring out the rest of the wall to improve insulation.
我已经将刚性的泡沫板连接到混凝土上。我会弄脏墙壁，以便将玻璃纤维绝缘放入2×6的墙壁上。
The outside of the house has shiplap sheathing nailed to the studs, a layer of building paper on top of the sheathing and cedar siding directly on top of the building paper. How do i properly insulate this exterior wall?

Q. "The outside of the house has shiplap sheathing nailed to the studs, a layer of building paper on top of the sheathing and cedar siding directly on top of the building paper. How do I properly insulate this exterior wall?"
答：可以用多种隔热材料将这堵墙隔热。如果安装正确，则以下任何材料都可以使用：纤维素，矿物质羊毛，玻璃纤维，开孔喷雾泡沫或闭孔喷雾泡沫。
你应该选择什么？这取决于您的R值目标和预算。
在所有情况下，您都需要密切注意气密性 - 尤其是考虑到外部漏水。（板护套通常比OSB或胶合板护套更漏。）如果您选择安装喷雾泡沫绝缘材料，则喷雾泡沫绝缘材料将在空气密封方面做得很好。您可能需要考虑闪光和棒的方法。有关更多信息，请参阅"Flash-and-Batt Insulation."
凭借蓬松的绝缘材料（没有喷雾泡沫），在绝缘之前，您必须填补护套的主要裂缝，这很耗时。您可能还需要以密封的方式安装内部干墙（这意味着要投资密封电盒）。
最后，如果您的目标是高R值，则可能需要考虑安装内部刚性泡沫。有关此方法的更多信息，请参阅"Walls With Interior Rigid Foam."
我的预算不允许喷泡沫。有any other options? Could i staple building paper to the shiplap or even tyvek (i have leftovers)?
公元前。，
问：“我的预算不允许喷雾泡沫。”
A. Then you should buy a case or two of good caulk.
Q. "Are there any other options? Could I staple building paper to the shiplap or even Tyvek?"
答：是的，您可以，但是（a）建筑纸不是一个好的空气屏障，（b）Tyvek不是空气屏障以及Tyvek到木材框架的接缝。这是劳动密集型且昂贵的 - 因此，购买一两个喷雾泡沫套件（在Lumberyards可用）可能会便宜。
有a certain brand or type you would recommend? I don't want to purchase the wrong type of foam. I guess I would spray vertically along the studs and horizontally into each seam of the shiplap?
谢谢您的帮助
B.C. Bud,
There is no inexpensive way to air seal this type of sheathing from the interior. How you proceed depends on your energy performance goal and your budget.
如果您想要一个好的空气密封，并且您的时间比金钱要多，我想您可以尝试用高质量的填缝到每个接缝。
If you can scrape together enough money, you can use the flash-and-batt approach -- either with two-component spray foam kits (all brands are similar) or with a spray foam contractor's help. In most cases, hiring a spray foam contractor for a flash-and-batt job is cheaper than buying several kits for a DIY approach.
If you don't have enough money or time for either of these approaches, you can slip narrow rectangles of asphalt felt into each stud bay and call it good enough. You'll have more air leakage with this approach, but it will be cheap.
除了一两个填缝外，您还应该投资商业级泡沫系统和枪支。希尔蒂做得很好。您将节省金钱，而不是购买很多很棒的东西，也可以找到更好的工作。上帝的经验法则是，应该填补小于1/4“的关节，但应该比这更宽。可以办到。
When furring out the 2" to accommodate batts designed for 2x6 framing consider using Bonfigliioli strips made of 1" or 1.25" (if you can find it) foil faced polyiso and 1x furring rather than solid wood. With R6 on the framing it cuts the framing fraction's losses by more than half compared to solid wood. See:

使用3-5英寸宽的钢制壁板胶带剪刀在边缘上磨刀和直边很止痛。

Could I use a combination of foam board and fiberglass insulation? I have already purchased the fiberglass ( 2x6 type) and find foam board very easy to work with. Example: a 1/2 layer of foam board against the ship lap and the 2x6 fiberglass on top of that?

问：“我可以将泡沫板和玻璃纤维绝缘的组合使用吗？示例：在船圈和2x6玻璃纤维上的1/2英寸泡沫板上？”
答：是的，在您相对温和的气候区域，该方法将起作用。（但是，在寒冷气候下的任何GBA读者都应意识到在寒冷的气候中需要更厚的刚性泡沫。）
