Sliding Glass Patio Doors for Washington, DC, Maryland & Northern Virginia

Sliding glass patio doors aren’t just for “lifestyles of the rich and famous.” They are for any home of any size and architectural styling, but they do feel luxurious. Their openings are large, but unlike “regular” doors, they require very little space to operate. Patio doors offer an entrance with a view.

Take advantage of your surroundings and bring the outside in! Call 301-337-5656 or contact Zen Windows DC today to learn more about the advantages of sliding glass doors.

What Is a Sliding Glass Door?

A sliding glass patio door is made of two large glass sections big enough for average adults to enter or exit. One of the glass segments is fixed in place. The other glass panel slides along horizontal tracks in the wall. Plastic rollers are sometimes on the top or bottom of the door for easier movement.

Where Are Sliding Glass Doors Used?

They’re called “patio doors” because that’s usually where they’re found in homes. But they can be used in many different settings:

  • Bathrooms
  • Closets
  • Hallways
  • Offices
  • Outdoor kitchens
  • Pools/spa areas

Sliding glass doors can be used anywhere in a house or commercial property for beauty, convenience, and visibility. Window treatments are innovative and attractive for occasional privacy.

8 Advantages of Sliding Glass Patio Doors

Humans seek, first and foremost, weather protection. Architecture has evolved, thanks to the one person who said, “It’s too dark in this cave.” Today, we want weather protection, comfort, and security. With a view.

Natural sunlight is a terrific way to add warmth and comfort to any room. Sliding glass doors offer a large window to the world without sacrificing security or energy.

Sliding glass doors are:

  1. A good investment – You’ll increase the value of your home and add to its curb appeal.
  2. Durable – Sliding glass doors should operate easily for accessibility. That means they need to be well-constructed of quality materials to outlast frequent motion and use.
  3. Enjoyable – You’ll enjoy your own view of your landscape, or patio/pool setting every day.
  4. High-performance – Save energy (and money); sliding glass doors keep you cool in the summer and warm in the winter.
  5. Safe – Our locking systems offer greater security and a tight seal for extra weather protection.
  6. Space-savers – You can install a large patio door in a small room because you don’t need the swing-space most doors require.
  7. Ventilation conductors – One way to promote cleaner, fresher IAQ (indoor air quality) is to frequently introduce outdoor air into your home.
  8. Versatile/attractive – There are several glass and finish options from which to choose. And glass patio doors add a look of luxury and sophistication to any room.

Bring the outside inside! Keep an eye on the kids or enjoy a beautiful snowfall on a wintry day. Enjoy beauty without compromise. Call 301-337-5656 or contact Zen Windows DC today.
