I was wondering if any of you can help me out. I know the answer is dependent on what one's range of brands is, but I wanted to find out what a professional versus a layperson would consider a mid-grade window product. We have specified in our plan aluminum windows, with most of the house being built with mid to high grade materials/products.

As I am waiting to hear back from several contractors, I am curious as to what brands or series within a brand would be considered mid-grade.

I appreciate any comments you have to offer. Thanks in advance.
