As a second entrance to your sunroom, you could add this decorative double door. The door is actually insulated steel, on a wood frame, with a full length window. The window is a single pane of glass, with muntins that give the appearance of 15 individual pieces of glass per door. (Yes, they are called muntins - or to some folks, muttons, but you really get that from sheep). Often confused with mullions, which are the structural wood or plastic used to divide the windows if the were individual smaller glass windows, muntins are purely decorative and not structural. Anyways... These doors are solid, and let in a lot of sunlight, which is the whole purpose of the sunroom to begin with, right?

Features:
Lock and Handle with 2 keys
Single Pane Glass
Mullions on outside of door glass
Door is 36" wide(each 72" total) x 72" high
