How Does a Dog Door in a Sliding Glass Door work?

This innovative system does not require any alterations to your existing sliding door. Instead, it replaces the glass panel with a pane of glass that has the pet door built in. The Sliding Glass Dog Door does not require any special fasteners, making it easy to install, and is custom built to the size of your existing door frame. Your sliding patio door will slide, function, and lock just like before. The pet door panel will not interfere with secondary locks or alarm systems, and the pet opening itself is easy to use and features a solid security panel.

Why is Ours the Best Sliding Glass Dog Door?

When you use a panel insert pet door that you just close your door on, you lose functionality of that door. Our in glass pet doors maintain functionality and normal use of your sliding glass door. This is especially important if your door frame is on the smaller side; the “through glass” pet door won’t force you to cram through the tiny opening sideways. Our custom built doors allow you to use the existing lock on your sliding door to secure your home.

How Much Does the Sliding Glass Dog Door Cost?

This custom built product costs less than many of our competitors systems, plus you get a lot more value for your investment. You choose the look of the door, style and tint of the glass and the pet door opening option. We fit the sliding glass pet door system to the door you already have in place. Contact us and we will discuss which size door and options will meet yours and your pets needs.


Frequently Asked Questions

Which Pets Can Use These Pet Doors?

What Color Options Are Available?

How Big Should The Opening Be For The Pet Door?
There are a few factors that play into this answer. Check out our page about how to Measure for a Sliding Glass Pet Door (we need to create this page and write the content).
Why Not Just Cut Into the Existing Glass Door or Window?
Glass doors and windows are made from many different types of glass. Each one of these require different procedures to cut into or replace. Tempered or dual pane glass will shatter if you attempt to cut a hole in it. Other types of glass will crack creating a potentially dangerous hazard.
How Do I Keep Other Pets From Getting Into My Home?
The most common concern is another animal, whether it’s the neighbors dog or wildlife, getting into your home through the pet door. This is rarely an issue. Insects and very small animals are not strong enough to push through the flap, and most larger ones will not bother to push against something that is tightly sealed to the frame and floor. Because of our products high quality weather stripping, strong magnets along all free edges, and stainless steel strike there are no gaps around the edges of the sliding glass dog door. It is always a great idea to keep food and water away from the pet door so hungry animals are tempted to follow their noses inside.
Are these doors easy to install?
Our professional installers have the training and experience to get your new sliding glass pet door set up in as little as 30 minutes.
Are Pet Doors Energy Efficient?
New advances in technology have made pet doors more energy efficient. Learn more about our technology here (this should be a link to the energy efficiency).
Will I Need To Train My Pet To Use The Door?

Some pets pick up using the door and immediately start taking advantage of all their new freedoms to come and go as needed, others need a little bit of help and training, If you pet needs some training here are a few things to try:

  • Lift the flap and show them the way in and out.
  • Sit on the opposite side of the door than your pet and squeak their favorite toy, offer a treat, or call them to lure them through.
  • If that doesn’t work try propping the door open. When your pet get into the habit of using the Pet Door to go in and out you can lower the flap.

Insulated Sliding Glass Dog Door with Advanced Components

Inexpensive pet door inserts have overwhelmed the market. These products are usually single-paned glass in an aluminum frame causing homeowners utility bills to skyrocket because they are designed to be cheap, not energy efficient. The sliding glass pet door from Viva Windows features insulated safety glass, dual seal silicone and highly energy efficient Vinyl frames, packing in major energy savings over time.

The Endura Pet Flap, made from specially designed polyolefin-based, stand out against all other pet flaps on the market.

  • Our pet fap is soft and flexible meaning it won’t pinch or injure your pet like most rigid flaps on the market.
  • The flap seals quickly and securely after your pet enters or exits, keeping inclement weather and unwanted wild animals outside where they belong.
  • Magnetic strips line the sides and bottom of the pet flap, creating a tight seal. Most commercial pet flaps hang loosely or, at best, use one or two magnets along the edges.
  • Our pet flap lives up to its name as a durable, UV retardant flap that stays flexible up to -40 degrees Fahrenheit. Most soft vinyl flaps need frequent replacement because they wrinkle and crack in the sun and get stiff or break in cold climates.
