WhatS our house like? Post picture and also of the window you plan to use. There is also Marvin windows. And many others.

Replacing all windows and doors and A frame addition on back

We are using Anderson 400 , recommended by our architect as a great mid range window. I have heard that Marvin is more expensive and the Anderson is just as nice, depending on your house. If it is a million dollar house you will want a higher quality window. . I haven't heard of the alside ultramax.

Windows/siding+dryvit/ doors

If your Architect recommended these windows to you, then I am sure you will be pleased with them. They look nice. Rather traditional, if thats what you are looking for. You see, and bty001is giving you a testimonial.

You are aware, though, tat dry it went though some terrible court cases, because that siding failed, at least in every building in our area. I am amazed that they are still around. Ask your architect.
