Designed for the modern pet lover, pet doors for sliding glass doors offers a blend of quality, convenience, and style. These pet doors provide an uncomplicated solution for those seeking to add a pet entryway to their sliding glass doors without undergoing tedious installations or modifications. Complementing the aesthetic of your home, they are compatible with various sliding door materials including aluminum, vinyl, and wood, ensuring a seamless integration that doesn't compromise on your decor.

For those considering their home's energy efficiency, many of these pet doors offer a great advantage. Designed to conserve heat during cold months and keep your home cool in warmer climates, these doors are an eco-friendly choice that also assists in reducing your energy bills. You can select from single flap options ideal for temperate climates or double flap models that offer an insulating air buffer, perfect for moderate weather conditions.

Customization is key, especially since matching your patio panel frame material to your existing door frame will reduce condensation. That's why many patio panel frames are available in both aluminum and vinyl.

These panels are not only durable but also provide an aesthetic look, blending in perfectly with your existing slider. Safety, an essential aspect, has also been taken into account. Many sliding glass door panels come equipped with a sturdy thermoplastic locking cover and a clamp lock system to secure the panel, effectively keeping unwanted visitors out when needed.

These pet doors are available in various sizes to cater to your pets' needs. The flap size and step-over height are designed to provide your pet with a comfortable and accessible entryway. Many patio panels have an adjustable panel height to fit your sliding door’s track height accurately. Regardless of whether you're a dog or a cat parent, sliding glass pet doors cater to all, offering the versatility needed in a multi-pet household.

Investing in pet doors for sliding glass doors is a step towards enhancing your home's convenience and comfort, all while providing your beloved pet with the freedom to explore. Its energy-efficient design, ease of installation, range of sizes, and compatibility with different door materials make it a worthy addition to any pet-friendly household.

Single Flap Vs. Double Flap

Single Flap: Dragon single flap options are ideal for temperate climates. It is also a good option for very timid pets who may shy away from a double flap.

Double Flap: Dragon single flap options are ideal for moderate climates. The space between the two flaps creates an insulating air buffer for improved energy efficiency.

Can’t decide between a single or double flap? Every Dragon pet door model can be easily converted from single to double flap with a few easy steps. You can start out with a single flap and upgrade to a double flap at any time by installing an Additional Dragon Flap.

Aluminum Vs. Vinyl Panels

How to Determine if Your Slider Frame is Vinyl or Aluminum:

  • Tap the frame: An aluminum sliding patio door will sound metallic while a vinyl one will make a dull, plastic noise.
  • Measure Track Width: Vinyl tracks are often slightly wider than aluminum. Aluminum tracks are generally 1” wide while vinyl tracks are about 1.5” wide.

Aluminum Panels: Aluminum Dragon panels fit aluminum doors with tracks at least 1” thick. They will fit vinyl doors with tracks at least 1” thick too, however, since vinyl doors generally have wider tracks the panel may wobble a bit.

Vinyl Panels: The Dragon Vinyl Panel is designed to fit in vinyl-framed sliding doors with tracks at least 1” thick. The vinyl pet door panel framing will match your existing slider for an aesthetic look. Vinyl is also excellent for cold weather, as it resists the “sweating” (condensation buildup) that aluminum can be prone to in cold climates.

How to Measure Track Height

It’s important that you make sure your Dragon pet door panel fits your sliding door before you purchase it, which means you’re going to need to measure your sliding door’s track height. To measure your patio sliding door’s track height, use a tape measure to find the distance from your bottom track to your upper track.

Start from the deepest point in the lower track and measure up to the deepest point in the upper track, as this is where the panel will sit. You will also need to use the tape measure to find the width of your track, which needs to be at least 1” for aluminum panels and at least 1.5” for vinyl panels.

Locking & Security

Locking the Flap: All Dragon Pet Door models come with a sturdy thermoplastic Locking Cover to block access to the pet door as needed. The locking cover keeps neighborhood critters out of your home and allows you to lock the flap at night or when you’re away.

Locking the Panel: Dragon slider inserts come with a clamp lock that attaches to the flange of the track at the edge of the sliding door panel. This clamp securely locks the slider to prevent access while you’re away. When you want to open your door, simply remove the clamp lock. For additional security, we recommend a wooden dowel or Charley Bar. The Charley Bar can be unlocked in a matter of seconds to open your sliding door.

How to Measure Your Pet

Measuring your pet is crucial to choosing the right door for your pet’s safety and comfort. To find your dog’s shoulder height measure from the floor to the top of their withers. The step-over height should be as low as possible for comfortable use by your pet, especially as they grow older. You can use the formula below:

Step Over + Flap Height = At least 1" Taller than Your Dog’s Shoulder Height.
