Can I spray foam insulate from the outside?

June 6, 2019Last updated: Aug. 3, 2020
我在不列颠哥伦比亚省的吉布森买了一栋旧房子，墙板需要更换。我想利用这个机会把暴露出来的壁腔密封起来并加以隔离。我期望看到不充分或没有绝缘。在喷涂泡沫什么是最好的应用(特卫强vs.其他)之前安装新的板和板条墙板?
Thank you, Kurt
Are you not expecting to see some sort of sheathing behind the siding? In order tospray foamproperly from the outside you would need to see bare studs, and spray foam in the stud cavities. So that would leave you without sheathing, so you would need to re-install sheathing or at least wind bracing if we are understanding you correctly. To re-install siding afterwards you would be wise to create an air space so the exterior of the wall can dry. Here is ourhow to install siding properly video, and another onhow to install a weather barrier. And read here for more information aboutchoosing breathable weather barriers.

Exterior walls need greater protection because they are exposed to the outdoor elements. It is advised homeowners choose closed-cell high-density foam for exterior walls. Not only does it keep air and moisture out, but it also makes the exterior walls more structurally sound, adding strength to a home and making it more durable. Insulation in the exterior walls is more prone to becoming damaged, which is why it must offer superior strength and durability. High-density foam is ideal for exterior walls. Besides the added strength and protection it brings, there are other ahrefs= https //www.windsorsprayfoam.com/interior-and-exterior-walls.html benefits
