How to properly seal the exterior of your house with rigid foam?

Daox · 10-19-12, 09:43 AM

This weekend I'll be doing a lot of work on my office remodel. I'm removing a door from an exterior wall, adding two windows in it, and will shortly after be adding cellulose insulation.

However, my question is about the exterior and how to properly seal it. The exterior sheathing on my house is wood planks. The wood plans are covered by 1/2" polystryrene XPS insulation, and then I have vinyl siding over that. I'm going to be removing the vinyl siding to install the windows and remove the door. Once things are all in place, what needs to be done to seal that XPS so that it seals the wall?
