AnnieM - 2300 installed sounds like a great deal for a 12 foot slider! Were those quotes for the same window, Milgard Tuscany? If so, I will need to look into that, looks great. What is it made out of? Vinyl? Fiberglass? I live in Northern California, weather is fairly mild, but I will be looking for double glazing and reasonably good sealing. I think I can get some imported Brazilian mahogany French doors for around $2,000 pre-hung with double glazed panes. I think I will go that if I can't find affordable sliders. I have one of these on my house now and it has held up well. Only thing is the muntins are kind of thick, and I think that is true of most of the wood French doors with true divided lights.

Thank you Toddimn and EcoStarRemodel. Toddimn, thanks for the warning about the need to install a header if we combine the windows. We'll definitely look into what is involved before deciding if we want to go that route. I went to another window store that had a better variety of display windows. They carry only Milgard. Milgard seems to have the corner on the market in this area. After seeing the both the Style Line and Tuscany windows, I would definitely choose Tuscany. The Style line have thin, unimpressive frames and look very similar to our aluminum windows. The Tuscany frames are much beefier, more like a wood window. The uneven sight lines in the Style Line windows doesn't look good to me. The operable windows have glass that is at least 2" smaller, whereas the Tuscany windows have matching glass sizes. The Tuscany locks are nicer and the weepholes are covered. Montecito is the same frame as the Tuscany. The Montecito lacks a few of the nicer features of the Tuscany and doesn't have the glass breakage warranty. The saleslady told me that the price of the two lines is almost the same ( usually within $2 to $5) so she doesn't ever sell the Montecito. Home Depot gave me a quote for Montecito windows. That might be one good reason to buy from a window supplier rather than Home Depot. Neither window store that I visited had any double hung window displays. I would be interested to see one. I was told that the double hung windows have thicker frames than the single hung. I don't think I would want an even thicker frame for our narrow kitchen windows so the double hung might not work for our home. I guess the single hung could look mismatched since the screen is only on the bottom but I wonder if it would be annoying to have to look out a screen at the top? I will do the contoured grids just in the top of the windows. They don't come in a smaller size. EcoStarRemodel, the window salesperson said that they can order picture windows with frames to match casement windows. She suggested making the two center windows into one picture window and putting casements on the sides. That way the view in the middle wouldn't be obstructed by the center bar of a double casement. However, she said that the picture window in a casement frame would cost almost as much as a casement window. I didn't realize that all of the windows in the house should be of the same type If that's the case, then I wouldn't want to go with casements. We would need 13 of them which would be way too much $$$. Would it also look weird if we combined the two center kitchen windows into a picture window with single hungs on all the other windows?

We do offer French Rail sliding doors and other patio doors with in swing french doors in our Tuscany series. Let me know if you have any questions/ concerns.

If you have the budget for your "dreams", go for it. If not, Stay with the Tuscany theme. You can mix a stacking door in but not sure a black door would work with your other white Tuscany doors.
