They are Canadian but maybe helpful to the next guy.
The health issues usually associated with spray foam have been pretty much eliminated in today's products. There are two types, open-cell and closed-cell. Closed-cell has a higher R-value, is water tight and adds structural strength and it appears that's what this company is using. Open-cell is usually preferred in homes because water leaks in the roof are easier to detect since the water will seep thru this form of spray foam. It does have a lower R-value and doesn't add any structural strength though.
I've used both. Had closed-cell installed in my RV Barn and open-cell installed in my home. In my opinion you selected the right stuff for your project, although I think I would have installed the wiring before the foam.
