How to attatch rigid insulation to old house - furring out window?
We are building a house in Northern Canada and I am not sure the next step. The house is 2400 sq. feet, 5/8" drywall, vapor barrier, 2x3 horizontal strapping with R-8 batts, 2x6 wall with R-20 batts, OSB sheathing, house wrap, and I want to add 2" rigid to the exterior of the house. The house has a HRV system throughout, electric baseboard heating, and the roof is R60 blow in. My question is in regards to how to add the rigid to the exterior of the house. Do I glue the rigid on, and then strap vertically through the insulation and to the house studs?? How do I fur out the existing windows to match the new level of rigid and vinyl siding that we will attach? I am all new to this, so any advice is welcome. Thank you in advance.
