How do I insulate a garage with a cathedral ceiling
首先，感谢所有帮助我开始绝缘车库的人。我在2辆车独立车库中隔离墙壁和门的路上很愉快。我正处于需要决定上述要做什么的地步。最初，我的曾祖父建造了一个天花板，形成了一个迷你储物阁楼。多年来，浣熊和松鼠已经找到了一种将其变成公寓的方法，因此我不得不将整个阁楼地板撕开。这真是令人作呕，很可能我必须处理的工作更糟糕。不确定我是否应该重建阁楼地板并将其隔离，因为我可能会遇到同样的问题。我不知道如果墙壁隔离，我是否需要隔离屋顶，我很清楚热量会升高，但计划在冬天最多加热车库一个小时，然后离开。我不想喷射绝缘材料，因为我想DIY。我可以将纤维隔热板放入与OSB靠近，但我对整个通风的事情感到困惑。 I saw one video where a guy attached foam board inbetween joists and then used spray foam for gaps and just left it like that. What is most economical solution, I’m in downstate NY climate zone 5 I believe, pictures attached.

嗨，乔。
I could only speculate about how much or little insulating and air sealing you need to do to be able to make your garage comfortable for an hour a day. And I'm sure how you heat it will be part of the equation too. In any case, an insulated roof can work as both vented or unvented assemblies, but the insulating strategies differ for each. This article will get you on your way to understanding how to insulate the roof:How to Build an Insulated Cathedral Ceiling.
Brian thanks again for your help. Read through the article and the many choices but I think closed cell spray foam is the best and safest choice. I see there are diy spray foam kits, not sure how much I would need and if the cost would get out of hand. If I did use spray foam could I leave it exposed after or would I need to cover it? Other option is insulated fiberglass batt walls and insulated garage doors but the roof left uninsulated would it still help with some heat loss? Willing to leave ceiling exposed if I could make up for it with more intense heating.
对于大型区域我不确定DIY喷雾泡沫is advisable. There are horror stories of bad spray foam installs that didn’t cure properly and health risks with spraying it, plus the kits cost $1.5 per 1” sqft which may be about the same as hiring a pro. You might consider cut and cobble if going diy route, which is spray foaming the edges of rigid insulation.
卡森（Carson），如果我使用cutt和鹅卵石方法，我可以将刚性泡沫直接粘在屋顶护套的底面，那么刚性泡沫需要多么厚？之后，我需要再添加绝缘材料，并且需要用OSB或干墙完成墙壁，或者可以将隔热材料暴露出来。绝缘墙时我需要使用相同的方法，还是可以使用玻璃纤维棒
搜索该站点如何隔离大教堂天花板，马丁直接就此主题进行了一篇文章。根据气候区域，您需要最小的泡沫厚度。有很多选择，玻璃纤维是一个选择壁和屋顶。在泡沫下，您可能需要像石膏板这样的防火，才能遵循代码。
Cut and cobble is a waste of time and is a risky assembly as it is impossible to get it air tight.
Looks like your have a simple gable structure, which means if you need to, you can easily add soffit to ridge vents. Most likely this won't be needed, but if you end up with condensation issues, it is something that can be easily added.
The budget way of insulating workshops is mineral wool batts that are undersized for the rafters covered by an air control layer. The undersized batts keep a channel above open so you can vent the roof if needed.
空气屏障可能是详细的房屋包裹，一层胶带OSB或石膏板。确保此空气屏障也密封在您的墙壁上。
我意识到剪裁和鹅卵石不是首选方法，但我正在努力省钱。堆叠2层刚性泡沫的“煎饼方法”呢？然后，海湾将完全充满闭孔泡沫。这种方法是否遇到问题的可能性较小，因为我没有在独立的未通风车库中使用巴特。我也会在墙壁上使用它，因此霉菌不会担心。我的意思是，这种方法也可以在地下室工作，这是我的下一个项目，但是我将使用刚性泡沫对抗墙壁，然后使用未取代的巴茨。基本上，堆叠刚性泡沫的缺点是什么？无论水分在哪里，似乎都是完美的解决方案
Is it correct to say that you are trying to avoid animals by doing a cathedral ceiling. A flying squirrel family of 4 I have met would likely laugh at that assumption. just put back a flat ceiling and block the holes for the critters the best you can.
汤姆，是的，这是一个假设，如果我没有单独的阁楼，它将阻止动物起床。我认为他们喜欢阁楼的黑暗。还有其他绿色方法可以阻止他们卧床间，只是检查任何入口吗？松鼠并不糟糕，而是浣熊。我在纽约市郊区，这些浣熊很聪明。当我搬进去时，那里被忽略了，只是不想再次铲除大量的浣熊粪便。但是，将煎饼堆放为建筑物方法呢？
