For building envelopes (commerical)

Is comcheck still used throughout the industry?
Any other / better software out there?

IECC Presciptive?

Curious what everyone is using

I'd like to use the following: https://www.homedepot.ca/product/durospan-gps-r10-2-13-inch-x-48-inch-x-96-inch-r-value-10-gps-rigid-insulation-foam-board/1001211235

The plan is Durospan GPS R10 -> Framing -> Rockwool Mineral Wool R14. This is for interior basement walls, up against the basement foundation (poured concrete)

Originally I was going to use XPS, but the GPS is half the price and the same R rating so I'm thinking I order this. My issue now is that I can't actually find anything online confirming what kind of adhesive to use with this laminated board so that it adheres well, and doesn't damage the insulation.

Any recommendations/experience with this? I'm in Ontario, canada if it helps!

I'm having my modified bitumen roof replaced. It's a flat roofed old Chicago brick 2 flat built in the 1920s.

One side of the brick parapet wall was badly damaged and I rebuilt it. Now, I'm trying to figure out how to re install the Terra Cotta coping tiles. I understand the direction they should be oriented to shed water but how are they attached? The old ones came off easily without breaking, maybe because the mortar was so badly decayed. Should I pre soak them, lay a mortar bed and set them in the mortar, or be more sparing, using mortar at the joints and only a few places to adhere the tiles?
