I avoid mixing window lines.

+1, The Narrow frame Elevate looks to be sold as an insert only. would not recommend pushing it past the sheathing. Not a fan of direct sets either. You could do all without nail fins or be creativeneith the trim to five them a more similar appearance but I would do all the same line and maybe alter sizes so they could be done that way and all with fins .

@toddinmn the direct set is still part of the elevate series. I just want to know what is best practice when using the elevate line. the profiles all look so different (direct set, casement, picture) . we have one very large window that we need to push to ultimate but we can live with butt joints vs miter.

I would go with standard casements so you can go with nail fins. It appears the direct set units. Have nail fins availble as well. I am not familiar enough with Marvins or all there options that would work best for you, hopefully you would have salesperson that could guide you better.

I am quite familiar with Marvin and until now have not heard the term "Narrow Frame" Elevate. That is used to refer to the Ultimate line. That aluminum clad casement actually started as a replacement product and morphed into a Contemporary or the "Narrow Frame" because of the smaller jamb availability.

That same term is now being applied (maybe by your dealer) to what was also brought to market as the Elevate insert or replacement products (without fins). Mixing Ultimate and Elevate is tricky but can be done. Just don't put them to close together. Also in new construction, I would not use a non-finned window as weather proofing is nearly impossible unless you are in a completely protected area on all four elevations. Be careful is all I can advise.

This detail you provided has printed at the bottom "Head Jam and Sill - Installed in Existing Framing", so it is meant for remodeling projects. Talk to your Marvin Window supplier.

@eastbay10 This is the elevation of the house - the ultimate is close but we made it "narrow frame" bring the exterior trim flush like the Elevate. I know that it is butt joints, not miter, but that should be ok.

@Todd Just came across this thread researching something else. I realize I'm likely too late, but thought I'd weigh in just in case.

You absolutely *can* use the Elevate narrow frame units in new construction, rather than only as inserts. I just did this on my own house. Also, while the details are not pictured with nailing fins, you can specify with your Marvin dealer to have them. (You can see a slot in the frame that receives the fin.) In fact, I believe the default is to include them. I assume they aren't pictured because they are being shown as inserts instead of "stand alone" units.

I question why you have narrow frame casements but "non narrow frame" direct sets. Why not use the same frame depth for both so the interior details are similar? Alternatively, you could use narrow frame picture windows (stationary unit with casement sash) so the frame condition at the exterior matches.

Again, just my two cents. Would love a follow up to hear how you settled to proceed.
