What is the difference between a patio door and a garden door?

Although patio doors and garden doors may seem like they’re the same, they are in fact different. Their similarities lie in their function but not their form. Both are placed at the back of a house to lead to the backyard, but patio doors slide on tracks, whereas garden doors open outwards. Also, patio doors consist of two doors and a screen where one door is fixed and the other operable. When it comes to garden doors, both doors are operable, but they do not have a screen. Garden doors are sometimes referred to as French doors.

Energy-efficient patio doors

One of the main benefits of our patio doors is their energy efficiency. Our energy-efficient patio doors are designed to keep heat in during the winter and keep it out in the summer. There is also a screen mechanism to keep bugs out so you can leave the door open and let air in whenever you please. Furthermore, our energy-efficient patio doors let in ample natural light, allowing you to enjoy an illuminated room that doesn’t require additional light sources during the day. Even on days when it’s overcast, you may not even need to turn on a lamp, saving you money on your energy bills. You’ll be pleased to know that our patio doors are Energy Star rated, making them the right choice for your home and your wallet.

Custom sliding patio doors

Not all patio doors are created equal. Some take up too much space, while others don’t let in enough light. Our patio doors can be customized to suit the space available and are energy efficient. We manufacture our custom sliding patio doors to your specifications, and they slide on their track from left to right. This ensures that they take up the least amount of floor space and provide you with an unobstructed view of your backyard.

We offer patio door installation services to our customers so they don’t have to lift a finger. Some companies only manufacture patio doors, but at Landmark Home Design, we are a full-service business. Our trained patio door installation team will complete the installation quickly yet carefully and clean up once they’re done. Any debris that has accumulated during the install will be removed, and you’ll be left to enjoy your beautiful new energy-efficient patio doors.
