We’re building a house in Barrie, Ontario which 2 layers of 2″ SM insulation on the foundatiion which will require covering above grade.
One option is to cover it with flashing, but there are drawbacks with that since the height to be covered is approx. 32″.
The preferred option is to mechanically fasten wire mesh to the SM and then parge the mesh. My question is this: What spacing of fasteners should I use to ensure proper attachment through 4″ of SM?
