What are the different types of pet doors?

Cat doors come in various shapes and sizes, but they can generally be classified into two categories: electronic and manual.

Electronic pet doors are more expensive than manual ones, but some prefer them because they’re less likely to get stuck in the rain or snow. Electronic pet doors into custom cut open and close automatically when your pet approaches. In contrast, manual doggie doors require you to open and close them yourself.

Manual pet doors are cost-effective and available in various sizes, so you can choose the one that best fits your pet’s body type. They also have multiple security features, such as locking mechanisms and adjustable thresholds, to keep out unwanted animals.

How are these doors in glass panes used?

Pet doors in glass panes allow pets access to the outdoors without going through the main entrance. The toughened glass doors are installed in a pane of glass in the door, and the pet can push through the opening to get outside. 

Some pet doors also have a locking mechanism to keep the pet inside when needed. All glass panels depend on the size of the pet. The larger the pet, the more generous the frame sizes. 

This is an excellent option for people who want their pets to be able to come and go as they please but don’t want to have to leave the door open for them all the time, and it’s also an excellent option for pets who are only sometimes good about staying on their property. All of which are made through custom-cut panels.

The Toughening Process & Generous Flap Size

Pets, particularly cats, tend to scratch around the edges of doorways. This can quickly wear away the sealant and damage the doorframe. By making the glass around the pet door and flap size generous, you can help to protect your pet door from being scratched or damaged. In addition, this will also help to keep your home nicer in the winter and colder in the summer by minimising drafts.

Toughened safety glass is an excellent way to strengthen the glass around the pet door. This is very handy for all pet sizes, all at no additional costs.

There are many reasons why you should invest in a glass dog or cat flap:

  1. They provide an extra layer of insulation for your home, which can help you save on energy costs.
  2. They’re perfect for pet owners who have allergies because they keep allergens and other pet hair out of the home.
  3. They’re much more secure than traditional metal or plastic pet doors, which burglars can easily break into.


If you’re considering investing in a glass dog or cat flap, be sure to choose one made from high-quality materials such as laminated glass or a-grade toughened safety glass designed to withstand the weather extremes in your area. Also, ensure the opening is the right size for your larger size pets.

How Do These Types Of Glass Add Value?

Dog doors can add value to a home in a few ways. The most obvious way is that it allows pet owners to quickly and conveniently give their pets access to the backyard or garden. This can be especially helpful in hot climates, where pets need to have access to shade and water or in cold temperatures, where they need to go outside for bathroom breaks.

Another way that dog doors can add value is by making a home more accessible for people with disabilities. For example, if someone uses a wheelchair, they may not be able to get outside quickly without a dog door. And finally, dog doors can also add value because they provide extra security for homes since they allow pet owners to keep an eye on their dogs from the inside.

Many pet doors come in all different sizes and materials, which include float glass, toughened A-grade safety glass, toughened glass panels, double-pane glass and many more.

So can you put a dog door in double-glazed door?

Yes, you can definitely put a doggie door in a double-glazed glass window. The dog door will need to be installed between the two panes of glass in the window. You will also need to make sure that there is a way to secure the dog door closed when it is not being used so that your dog cannot push it open and escape.

Before installing a dog door in a double-glazing window, the most crucial factor is the dog’s weight. A large dog can easily break the glass by pushing on the door, so it’s essential to ensure that the window is strong enough to support your pet’s weight.

Another thing to keep in mind is energy efficiency. If you’re planning to install a dog door in a double-glazed window, make sure that you choose an energy-efficient model that will minimise heat loss and save you money on your energy bills.

Common Identification Microchips Reader

Do you have a microchip pet door hole?

Microchip pets can work with door holes in a few different ways. One way is for the pet door to have a built-in scanner that will read the chip as the pet approaches. This type of system usually has a keypad on it, so you can enter a code to unlock the door for your pet.

Another way that microchip pets can work with pet doors is by using a remote control. With this system, you would carry around a small transmitter that would activate the pet door when you’re close to it. This system is beneficial if you have more than one pet since you can open the door for them at once.

This works for all panes of glass, including A-grade toughened safety glass or even your current glass for all pet sizes. Get in touch with your local qualified glaziers for more information.
