Sliding patio doors have the same advantages as French doors, but are much more sleek and convenient.
These doors have a built-in lock and blind system. Many models have permanent sealing, meaning that they are more secure and dust-free than other types. If you're concerned about safety, consider installing security features with patio doors to protect your home from intrusions. Depending on the style of your home, you may even be able to use security devices such as deadbolts and alarms to protect your home and property.
When choosing a door, consider what kind of climate you live in. While glass doors are generally more durable than others, the fact that they are usually made of glass doesn't mean they are better for the environment. For this reason, fiberglass is an excellent choice for patio doors. They won't fade or warp under harsh weather, and will keep your home cooler and dryer during cold weather. In the end, the choice will come down to personal preference.
