Our four season sunroom was built in 2014 though we now realize we should have done this years ago.
Visitors marvel at the brightness and quality of the room.
We use the sunroom a lot even in the middle of winter on sunny days with no heat on. In fact the room saves on energy costs, as on sunny days we open the door to our house to let the heat in.
No blinds needed for the summer months. With the overhang off the house, a big tree and the windows open the room stays comfortable even on the hottest days and best of all no bugs to bother us.
The sunroom has really enhanced our quality of life.
