Who says you have to only have one patio door on a sunroom? No one!Get creative and instead of just using windows and a single patio door in your sunroom, use a patio door on both sides of the sunroom. There are so many perks to creating this type of double-door set up that you will be glad you thought of it.Dual Patio Doors Create a Perfect AirflowCombining a patio door and a window across the room from it in a sunroom creates a nice cross breeze to cool the area quicker than a fan ever could. It works faster because you have one opening that is allowing the air from the outside in and pushing the warmer interior air out the other opening. With a fan, all you are doing is moving the air around.By replacing the window with a second patio door on the opposite of the sunroom of the initial patio door, you create a bigger opening for an even better cross breeze. In fact, this cross breeze is so good that it will almost feel like you are sitting outside.Have More Room to EntertainHaving patio doors opposite of each other in a sunroom gives you a bigger space to entertain in. When the dual patio doors are open it opens the sunroom up to the outside and creates a flow of one large area, instead of your yard being cut in half by part of your home.This more open area will allow you to entertain both inside and outside with everyone being able to be together instead of having to fit in multiple areas of your home.Don’t Forget the Patio Door Window TreatmentsDual patio doors do let in more sunshine that heats up the sunroom faster when it is hot outside, and lets in more cold air in the winter. To keep this under control there are two things that you can do with your dual patio doors.First, have energy-efficient patio doors installed. These patio doors prevent the hot and cold air transfer through the door better than regular patio doors.Second, put up some sort of window treatment. Window treatments act as a barrier between the glass in the patio door and the sunroom so that there is not as much heat transfer. They also give you privacy in your sunroom if you don’t want your dual patio doors making you feel like you live in a fishbowl.Source: http://www.houzz.com/photos/71028/Contemporary-Patio-contemporary-patio-other-metro
