Question on “Deep Set Brickmold Trim for Innie Windows”
Since I’m not a member I can’t ask questions about a Prime article (or read the entire article). Maybe this is addressed later on in the article but I don’t know.
The article states: “If you install flanged windows on the exterior side of a sheathed 2×4 or 2×6 wall, and you then install exterior rigid foam, you end up with an “innie” window.”
I’m guessing from this description that the window flange is installed right on top of the sheathing and/or WRB and then the rigid foam is butted up against the edge of the window? Shouldn’t there be a “picture frame” of 2x material around the window opening and if so then the window flange would be nailed to that (thus bringing the window farther out in the wall plane and resulting in less of an “innie” effect). The “picture frame” would also provide an edge for the rigid foam to butt up against.
I looked at the link for Northerm Windows provided in the article but couldn’t find any information on their trim design or whether they recommend applying it over a “picture frame” or not. Does anyone have drawings or sections of this products trim details?
