With the Daylight Max 7300 series of vinyl windows, you can expect less frame and more glass then any other vinyl window on the market. With a 2 7/8” frame depth, Daylight Max windows may not require you to replace your existing window treatments because their frame depth is not as thick as most competitors. Up against other manufacturers of vinyl windows, Simonton’s Daylight Max replacement windows have up to 40% more glass!
