We're in Mass and are selecting windows for our new build. It's a colonial and we're looking at wood interior with 12 over 12 grille pattern and I tend to like the look of the 5/8" muntins verus the 3/4". So far, I'm finding we seem to have to go custom for the 5/8" muntins. Our Architect mentioned Boston Sash, which I have never seen in person so I was wondering if anyone on here has used them? If so, do you know how they compare to Marvin Ultimate, Andersen Woodwright, or Green Mountain in quality and price? If you're in Mass and know of a good place to view them, that's helpful too!
Thanks in advance for any insight!
