Which type of exterior insulation to use on a house?
I want to first off thank you for taking the time to read this and hopefully provide some help. I've watched the great videos on here and just want to ensure I'm understanding everything completely before I go ahead and purchase/install the exterior insulation.
a little info on the existing house:
Its' in Northern Ontario , Canada. Atikokan to be specific.
The house has a brick front (which I won't be adding insulation to)
the other 3 sides a 2x4 framed , cavities filled with batt insulation and old 3 mil vapour barrier inside
The 2x4 framing is actually sheathed with a buffalo board type of material on the exterior rather than OSB (I'm assuming the builders saved a few dollars by using such a bad material?)
There is old aluminum siding which I am planning to remove at which time I want to add rigid insulation and then vinyl siding
My questions are the following....
哪种刚性绝缘体最适合这种应用。我主要关心的是在刚性绝缘和水牛板之间的蒸汽/湿度问题。
My original plan was to remove aluminum siding. Apply a "Tyvek" wrap, fasten 1.5" rigid to the studs. Then apply a royal building (brand) vinyl siding directly on top of the rigid insulation using 3" fasteners.
please let me know which product you would recommend for this type of application and if I am misunderstanding any of the steps needed to do this correctly .
Once again, thank you very much for taking the time to read this and also hopefully provide some insight.
To find the best exterior insulation to use when renovating old homes, we often recommend Mineral wool (often referred to as Roxul or Rockwool). We like it for the very reasons you mention, that it isn’t harmed by moisture and it lets moisture pass right through it. Here is the page you really need to read though, all about the various options for exterior rigid insulation so you know the characteristics of each –
Choosing the best exterior rigid insulation for renovating old home exteriors
Choosing insulation that won’t trap moisture is important, and after than be sure that you design your wall assembly in a way that it can dry to the exterior.这是我们的页面,关于如何安装外墙板,使它可以干燥。
You also mention using Tyvek, I would also point you to this page aboutchoosing exterior weather barriers (WRBs),因为这也是一个做空气屏障的好机会,当你在进行节能改造时,这对老房子来说是一个很好的升级,因为老房子很少有合适的空气屏障。如果这些页面没有回答你所有的问题,请回复我们,它们甚至可能激发出一系列新的问题,这也很好。
