Spray Foam Odor Help

Hello and thanks for looking at my post. I'm obviously new to this and am here out of desperation. I had a company install ThermoSeal closed and open cell into my home recently (last week 6/12,13,14). The closed cell has no odor but the open cell has a strong chemical odor. I've left windows open and have 3 fans going. The company put closed cell in all 2x4 framing and 2" on the roof deck then covered it with 6-8" (well thats what they said...Ive found many areas they were short or thin and they are returning to fix it) all of the 2x6 framing has the open cell.

Insulating on exterior of stone foundation

I am in the process of excavating and waterproofing a stone foundation on a century home. I am coating the wall with a rubber sealer, then wrapping foundation with a dimple membrane to grade height.

Would there be any benefit to adding rigid styrofoam up to the grade height? The stone wall from grade to first floor is 2 ft 6' . I don't want to cover this portion as I want the stone exposed. The interior stone wall is to be exposed as well. The basement floor has styrofoam insulation under it and has infloor heating. Any advice is appreciated. I am in the blue climate zone.

Clarification on 2009 IRC code requirement vs what's stated in article on building a Cathedral Ceiling

From the article I read: (i capitalized what im trying to get clarification on)

If you want to install a combination of rigid foam ON TOP of your roof sheathing and air-permeable insulation between your rafters, you need to be sure that your rigid foam is thick enough to keep your roof sheathing above the dew point. Guidelines to achieve that goal are included in the 2009 International Residential Code (IRC).

Why not integrate window exterior into WRB?

I've recently noticed that several folks are not advocating flashing the exterior side of windows (flanged or unflanged) into the water-resistive barrier (WRB), but instead propose that a properly flashed rough opening (RO) and an airtight interior is sufficient to manage water drainage and air sealing. Notwithstanding window manufacturer recommendations, would it not be prudent to flash the top and sides of the window to limit what water can make it into the RO in the first place? It's not much extra effort/expense.

Renovation with interior poly vapor barrier

We are working on a renovation including an addition of an existing house in Zone 5.

Existing wall: 2x6 @ 16" o.c. w/ fiberglass and an interior poly vapor barrier.

We would like to improve the R-value of the assembly, but will not be removing the plaster from the interior face of the majority of the walls. This means we do not have the opportunity to remove the vapor barrier.

As a result, do we lose the opportunity to add exterior polyiso, because of the resulting vapor barrier sandwich?

Sizing windows to correspond with advanced framed window openings

I'm designing a house and struggling a bit with window sizing in regards to advanced framing. I've noticed that more than one manufacturer offers standard sizes, in addition to custom-sizing their units in 1/8th inch increments. The standard size widths are in 4 inch increments, which accomodates the standard building practice of using two studs on each side of a window. This holds for off-the-shelf as well as catalog sizing.
