A cat flap could cause an air draught when left open. This is a problem that many cat owners have to deal with.
A draught excluder can help cut down the amount of cold air entering the house. However the cat flap offers better protection against the elements. Tomsgates provides a range of dog doors that are insulated and cat flaps that work for all types of installations, including wall installations.
The Material
Insulation is one of the most important features of a cat-door. Insulation is what keeps cold air out and warm inside. Insulation can be achieved in a variety of ways however the material that the flap is made is the most crucial.
A single flap won't do much in terms of insulation for your home But doors with triple or double flaps are far more insulated and will stop cold air entering the home. You can also buy draught restrictors that are fitted around the frame of the flap and help to reduce drafts. Be aware that they will not stop cold air from entering your home, if you're trying to open the door for your cat.

Another alternative is to fill the space left behind by your cat's flap some form of insulation like styrofoam. This will prevent cold air from entering your home, while also reducing the amount of noise that is produced when your cat uses their pet door. If you choose to do this, you should measure the hole your cat flap created and select a filler that is compatible with the surrounding fabric.
