The Andersen 400 Series has many more options than the Integrity, so if your looking for something other than "basic", it may be the better route. Also, the Andersen sash is clad all the way around, so if you leave a window open and it rains, the wood is still protected. With vacuumed formed cladding on the exterior, the Andersen doesn't have the seams and mitres that the integrity does, which is a common place for units to fail when it comes to water management. I've done a lot of building right on the ocean, and the Andersen casements are by far the best performing window we used in this hostile environment. Don't worry about the Home Depot factor. They sell the exact same window, but their service and product knowledge can be dreadful. I strongly recommend a full service lumber yard. It's well worth a little extra money. Hope this helps.

400 series casements are NOT vinyl per se, they are a vinyl clad (they call it Permashield) wood window. What exactly are you referring to as your concern? And what is that large brass colored screw doing there? The caulk in the corners is just that caulk, as far as other issues, not certain what you are speaking of but the installation is obviously not complete. Back up a little bit and take more pictures.

Wow vinyl clad priced higher than aluminum clad..windsor gettin down and dirty cheap...id let them work the kinks out first before buying windsor pocket window..i think that just hit the market not too long ago

Thanks for pointing out I wasn't clear on which Andersen line. It was the 100 series windows (I updated the post to clarify- thank you). I saw a sample on the floor of a window store where the sample was probably around 36"w X 48" tall. The frame didn't stand out as large. Unfortunately, most of my windows are narrower but the frame size is always 3". For example, I have 2 casements with a transom above (3 windows mulled together) where each casement in the pair is 24"w X 42"h - so the middle of this complete window is 6" of frame and the sides are 3". of frame.. that left only 18" of glass showing on each side with this 6" glob down the middle. Similarly, the transom across the top of the 2 casements is 48"w X 18"h and fully 1/3 of the window (6" of the 18" height) is frame - only 12" glass.
