(The image shown includes the OPTIONAL muntins (cross bars) in the upper pane. The muntins shown are used to simulate a classic 4-pane window in a single frame . The price shown in our store does not include the muntin option, which is, of course, available and can be a pleasant nod to simpler times (that didn’t include Sentinel hurricane-rated windows).

(Some of the optional items, particularly the muntin bars, are very detail-oriented and cannot be handled appropriately through a web store. Because of this, any options you might want should be discussed with your personal window consultant. We want to make this perfect for you, and sometimes there just is no substitute for a human voice.)
