What type of patio door should you have on your patio? French or sliding? Well, both doors have their own benefits. French doors offer more privacy because they come with two panels that slide across each other. Sliding doors do not include any solid material in them so they provide an open feel while allowing for maximum airflow. So if you want more privacy but also don’t mind sacrificing air flow then yes, go with French! However, if you prefer an open feeling where there is plenty of air circulating then go ahead and choose sliding!
