I looked at this product as well a couple of years ago.. Unfortunately I wasn't able to get the green light from the building officials as the product is not registered in Ontario. frown

Have you seen my post on REMOTE wall? It's a super easy system, fun to work with, especially when when working solo. The 4x8 foam panels are light, the 2x4 curtain wall can be built either 16 oc or 24oc and it goes up quite fast. My rough costing came out to just over $3/sqft for R34 wall (+ 3.5" airspace, which allows the foil to do it's thing). That is using foil faced polyiso panels and standard SPF studs.
