GET THESE FIVE TRICKY SPOTS RIGHT, AND YOU'LL GET A SUPERINSULATED, ENERGY-EFFICIENT HOME
An experienced builder explains the ins and outs of airtight exterior insulation

Installing rigid foam on the outside of a house is a great way to double the R-value and eliminate air leaks. Large sheets of foam insulation, screwed and sealed to the walls or roof, can cover or replace conventional sheathing and create a continuous barrier to heat loss or gain—something you don't get with cavity insulation alone. We wrapped the house in this video with 4 inches of polyisocyanurate in two staggered 2-inch layers...

Folks, check out REMOTE wall system. Residential Exterior Membrane Outside-insulation TEchnique

REMOTE puts outside insulation on the entire house. (roof and foundation) Just putting above grade wall exteriour insulation will not do the trick. Insulate all the framing or do nothing.

What are you actually mounting the windows to, since it looks like you only have that thin plywood window buck/extention there? I would think that this would not be strong enough, and instead of pw, you should maybe use a 2x material???

Avg extra cost.....@4000$ Cost per year with 7% morgage @300$ Savings per year with a 16 SEER 90 AFUE unit @ 100$/year. Oh this is why that isn't the standard in new construction? So many builders ready to spend a dollar to save a dime, so many customers willing to jump on the bandwagon, till they get to choose granite countertops, or foam board, fck the foam board. Granite may actually have a return on investment, by increasing the value of the home. Nobody will ever know/care about the foam

Great Video Thank you

This is awesome, and looks very good. Since you build the window boxes to accommodate the width of the insulation, it doesn't look like this could be done on a remodel.

Is the vapor barrier put on after the insulation? I'm a total noob.

Great general guide here, thank you for posting. One question though:

At the 90 degree flashing face where it meets the rigid stuff, do you caulk that? I'd imagine there is air loss if not.
