Benefits of Installing Patio & Sliding Doors in Your Home

Besides adding more beauty to your home, patio and sliding doors offer Denver homeowners a wide range of additional benefits. Here are some of the reasons sliding door installation is the right choice for your home:

  • Light: Sliding doors are mostly glass, allowing more natural light to flood your living space.
  • Airflow: Allow the fresh breeze to circulate through your home with wide openings available through sliding door operation. Slide the door on its track, leave it open, and bask in the mountain air.
  • Entertainment: Especially when hosting barbecues or family parties, sliding glass doors allow greater traffic flow through the home, making entertaining a breeze.
  • Space: Because sliding doors don’t swing open, they allow for increased space while providing easy access to the outdoors.

While homeowners in the past have raised concerns about the safety of sliding doors, advancements in glass and door manufacturing have improved their security. With thicker glass and available double-lock features, sliding doors provide equal parts beauty and security.

Some of the frequently asked questions we receive about replacement patio doors in Denver include:

Are patio doors safe?

Your patio doors provide as much protection as other exterior doors. What’s more, Zen Windows patio door replacements offer more protection than your older unit.

In addition to thick, energy-efficient glass, Zen Windows Denver patio door hardware is strong and durable. We have special locking systems and stronger latches for improved safety and security.

How long should sliding glass doors last?

If your patio doors were installed over 20 years ago, you’re probably due for a replacement. Your Denver patio doors have a lifetime warranty.

The insulation and energy efficiency of your Zen Windows patio door is so good it also qualifies for an ENERGY STAR® tax rebate. You’ll likely see lower energy bills every month.

What do I need to look for in a new patio door?

Before you invest in a patio door for your Colorado home or office, you need to measure. Are you stuck with your patio door size as is? Not at all. Your replacement patio door can be the same size or customized.

  • Maybe you’ll want a foot-operated deadbolt. Our security hardware is industry-best.
  • The material you choose makes a difference. We offer materials such as fiberglass, vinyl, and steel. Frame styles can also be customized to work with your architecture.
  • You have options for color and finish. If ambiance is important, you can opt for etched glass or grid inserts.
  • You’ll have several options for glass coating and insulation, and they’re all superior.

If you have sliding door problems, don’t wait to get a replacement. The air loss is costly, but the security risk is too high to delay.

Replace your older patio doors with low-maintenance, energy-efficient Zen Windows Denver patio doors. Our security features are the most effective on the market.

Our team uses technology to provide your quote. No mandatory home visit and no upselling. Just the most hassle-free experience you’ve ever had.

What kind of maintenance does a sliding glass patio door require?

In addition to keeping the glass clean (you’ll want the best view!), other regular maintenance tips include:

  • Dust the frame, then wipe it down with warm, soapy water. Don’t use harsh chemicals.
  • Dust tracks/rollers every month with warm, soapy water. (A toothbrush is excellent for hard-to-reach places.)
  • Lubricate the tracks (only when tracks are clean).
  • Replace worn weatherstripping (but you shouldn’t need weatherstripping with a Zen Windows patio door installation).

When should I replace my patio doors?

If your patio doors are 15–20 years old, you’re losing energy efficiency and compromising safety. Zen Windows Denver patio doors have a transferrable lifetime warranty.

You’re also not stuck with your patio door’s original location and size. There are several factors to consider, but you can update your sliding glass door system to work even better with your home’s architecture and layout.

Which patio door style is most energy-efficient?

Your insulated, energy-efficient Zen Windows patio door may qualify for a federal tax rebate. But the real savings is when your monthly energy bill arrives. You’ll likely see lower energy bills almost immediately after your Zen Windows Denver patio door installation.

Sliding glass patio doors are more energy-efficient because they have only two glass panels. French patio doors have four panels.

Zen Windows patio doors have increased thermal insulation when fitted with weatherproof and soundproof composite gaskets. Our glass glazes offer UV protection and additional thermal insulation.

Which patio door style is safest?

French-style patio doors remain popular, but Zen Windows Denver sliding glass patio doors provide superior safety. We use thick, energy-efficient glass and tough fiberglass, steel, or vinyl frames. Our patio door hardware is extra-strong and durable.

Zen Windows offers advanced locking systems, including a foot-operated deadbolt and stronger latches for improved security.
