Installing dogs and cat flaps in double glazing glass and UPVC patio doors

We look at some of the options for installing dog and cat flaps into your double glazing glass and UPVC patio doors

As dog and cat lovers, providing comfort, convenience and freedom for our pets is of utmost importance. Installing A cat or dog flap in UPVC double glazing patio doors is considered as one of the major ways to provide convenience and freedom for our four-legged friends. This can allow your pet to make the most of your home and garden when you’re not around.

These flaps installed into your glass door make it possible for our dogs and cats to easily go in and out of the house as they please without having to try and get the attention of someone. In other words, you are not going to be frequently hassled by your pets when they feel like going out. This is indeed truly important. Installing a dog or cat flap into your double glazing can also allow your pet to be left home alone for longer periods of time.

Choosing the right cat or dog flap for your home can be difficult, there are many options out there. There are many things you have to consider which include; the type of flap, size of flap, security and the type of door the flap is being installed into.

The type of door is a major issue to consider especially when working with a double glazed patio door. In this article, we break down the multiple options available when buying and installing dog and cat flaps into your double glazed doors.
If you already have a double glazing glass patio door installed, then the best thing to do is to contact a local double glazing company and discuss possible solutions for installing a dog or cat flap. Many local companies will have installed a pet flap before and will be able to offer advice on which particular flap will be best suited to your current door.
Although many cat and dog flaps state that DIY installation is possible, don’t go drilling holes into your door without any form of direction, as any slight damage can cause misting of your glass and air entering into your home.

If you’re having a new double glazing patio door installed, the best way to install a pet flap is to pre-order with the door. This is the most efficient and easiest method to insert a pet flap. Speak with your glazing company about the possible options when ordering your new door.
