I purchased the Marvin Utimate casements too and finding it difficult to find window treatments that fit inside these windows.. The grooves inside for their integrated shades prevents mounting of conventional window treatments using an inside mount. I also purchase a couple of Marvin Ultimates with the retractable screen and there does seem to be a Marvin solution for an integrated shade with it either. Anyone have a suggestion on this? I figured it out!. You do an inside mount on 1" part of the surrounding window inner surface.. It might leave a little sticking out depending on the 1" depth mini bind or cellular shade, but it is doable.

I strongly recommend that you avoid Marvin Windows. In 2011 I spent thousands installing what I believed to be high-end durable Marvin windows: 6 casements and 3 double hung. The casements are not durable and wear poorly. Within the first year, the hardware was broken and on several occasions I was unable to close one window (an "utlimate" casement with transom). The casement hardware is cheap and poorly designed. Here are specifics: 1 - Antique brass hardware on three casements is not solid and the finish peels and bubbles. Screws rusted, loosened and now protrude from the handles. In addition, the hardware is loose -- it jiggles when turning the handle. 2- The locking mechanism on the "ultimate" casement gets stuck on occasion. My contractor had to come open my window this week because it was cold -- there was a 1/4 inch gap between the two panels. In addition, the bottom sill is loose. 3 - Second floor casement windows have plastic hardware that are also loose. The tongue into which the lock slides keeps falling out. No problems with the double hung windows, which have solid metal hardware. To be clear, the problem is with the manufacturing, not with the distributor (Super Enterprises) which has been responsive. BOTTOM LINE: If you NEVER OPEN your windows, consider Marvin. Otherwise, look elsewhere.

Hello! Update: WIndows/Doors Choice is now between: (A) Milgard thermally improved A250 aluminum 16 windows - mixed casements and sliders, 3 sliding patio doors 96" X 82" and 1 sliding patio door 72" X 82". Quote for those installed is $44,000. or B) Milgard Ultra C650 fiberglass 16 windows - mixed casements and sliders, same size and number doors. Quote for those installed is $65,800. My understanding is choice (A) the fiberglass windows and doors will comply with Title 24 for my Bay Area home. But as they are $20K more, with fatter sightlines, we are considering hiring a company to provide us with "as built drawings" (floor plans) for our home, and we then hire a Title 24 consultant. My home will then be evaluated for energy efficiency and given a number. By undertaking other energy saving measures (new furnace, R38 insulation instead of more basic, and other measures I know not of, but hope to learn) we can make up the difference for the U value of 0.38 for Milgard thermally improved aluminum, which just misses the 0.30 of Title 24. Milgard standard aluminum has a U value 0.45. Has anyone else gone the energy survey route with a good result? Are these facts correct? Are these quotes fair for the Bay Area? This second contractor is also installing Hardie Board as I noted in my OP. (The first contractor failed to get back to us in time, and so here we are months later. Marvin still not an option, as he's not a certified installer and we'd have to buy them outright.) We are trying to move fast to avoid yet another price increase. Thanks. Should I start a new thread as Sierra Pacific is no longer in the running?

You could get lucky, but not likely! I had 2 extra Marvin windows and just told my builder to take them when he cleaned stuff up after we moved in in January! Marvin sent us 2 casements that opened in the wrong direction. The replacements took 5 months and I gave up at month 4 and just told the builder to keep the project moving with the wrong windows. No one else will notice. When the replacements arrived we had already completed stucco outside and trim inside, so I had no use for them. Mine were push out casement with retractable screens, Bronze outside and primed white inside, so they wouldn't have matched your project in any case.
