Our Octagon Sunrooms come standard with 7 large 40" x 60" Windows; one on each wall. These windows allow the maximum amount of sunlight to illuminate your sunroom. The windows start about a foot off the floor and reach to a foot from the top of the walls. When open, they also allow in the most breeze, while the screen keeps out the unwanted bugs. Windows have mullions on inside of glass as well as a lock. Of course as with any of our structures, you can customize your sunroom by having less windows as well. Be sure to discuss this with to your Project Advisor.
