A cat flap allows your pet to come and go as they please without opening the door for them. This is a great method to keep your pet safe in the home when you are away or at home. It also helps to keep unwanted pests from getting into your.
It is essential to measure the door before you buy a cat flap as there are different sizes available. This ensures you get the correct size that fits into your upvc door, otherwise, it might be too small or too large for your cat and he will have trouble using it.
Before you take any action, though, take a ruler and determine the length of the door in several places along its edges. Also, you should measure the door's height in a couple of places. This is because the door that is too high can cause your cat to do an exercise routine like a gymnast every time they use the flap!
Ask a glazier for assistance when you're unsure of what to measure for the door. They can determine if your door is suitable for cat flaps and can advise you on what size flap to buy.
After you've gotten your measurements, the next step to do is to draw out the shape of the hole in the door. This will give you an idea of how to cutting the hole out and will stop you from making an error that will cost you money in the end!

You should also make sure that the hole you're making is in the correct place. For instance, if fitting the cat flap in a patio door, it's important that the hole doesn't sit too close to hinges, as this could cause leakage and damage to the seal.
It is best to delegate the job of installing the cat flap on a glass door to a professional glazier. It may be difficult to install a cat-flap in an existing pane. You may also find that it breaks and loses its weatherproof seal.
Measure the Cat
A cat flap permits your pet to move around whenever they want without needing to leave them on their own. It can also prevent draughts entering your home, which isn't good for your cat or you.
If you do have a uPVC or composite door it can seem tricky to fit the cat flap. These doors are made of different materials and the process of installing them is different. Make sure to inquire with the manufacturer to see if it is compatible prior to installing the cat flap on your uPVC composite or uPVC door. Changes to the door could cause warranty issues.
They are designed to be durable and tough with insulation. They are more resistant to elements than other kinds of doors, but it isn't easy to install the cat flap. Get advice from a professional before installing a cat flap onto the uPVC door or composite.
You'll need to determine their height to ensure that they can fit through the door. It is easiest to measure their height when they are at peace or asleep, which means they don't move around. Once you've established their height, take a measurement of the distance between their stomachs and the floor to determine where the bottom of the cat flap should go. Then, you can mark this location on the door.
If your composite or uPVC door is made of metal (either steel or aluminium), you'll need to be very careful when cutting it with power tools. The act of drilling into the metal may cause cracks, particularly if the area is toughened glass. It is highly recommended to hire a glass installer when installing the cat flap inside a pane. This will prevent the glass from becoming fragile or shattering. A glazier will also be able to provide you with a cat flap that is less likely to break and safer for your cat to use.
Cut the Hole
A good cat flap will come with a drawing template that can be used to mark the location on your door where the hole should go. If it doesn't, you can make one yourself using an uncoated sheet of paper (tracing paper is the best choice). Once the shape has been drawn on the door, use your spirit level to make sure that it is horizontal. This will allow your cat flap to properly fit into the opening and stop it from being capable of sliding open or close.
Next, take your jigsaw and cut out the shape that has been drawn on the door. Make use of a blade specifically designed specifically for uPVC door use. It is usually identified with this information. If not, ask the staff in your DIY store for assistance. Once the hole is made, place the flap section against it and then open it to make sure the flap moves smoothly. If it binds at any point, you can use a file or a sandpaper to correct this.
Make sure there aren't any electric or gas pipes within the door you're going to cut through. The jigsaw may damage them. Also, be aware of any handles or other door fixtures which will need to be removed to make room for the cat flap and be careful not to damage them during this process.
Most people who fit the cat flap themselves have the standard solid uPVC door and won't have to deal with any of these issues. However, if your door is made from wood or has a decorative panel that cannot be removed, this could increase the difficulty of the task.
It is always worth seeking professional assistance from a cat flap fitter when it comes to these types of jobs because it is crucial to get them done right to avoid potential issues in the future. If you do it wrong, it could lead to the door being damaged and could invalidate the warranty.
Install the Flap
Once you have cut your hole, place the flap and check if it opens and fits. If you spot any areas that stick or catch or stick, you can file them down using a hand file or sandpaper until it fits properly and opens without any problems. Make sure the flap sits flush with the door too.
If your kit doesn't include an example, you could use tracing paper that is thin, such as a piece of paper or acetate. Place the paper against the door and draw an area on which you'll will need to place the flap (this will serve as your cutting guide). Draw four screw holes at every corner of the flap using the pencil marks you traced on the door. cat flap installers are the screws will be used to secure the flap to the door.
Most uPVC doors are strong and therefore easy to cut into. But, if your door is made from GRP or a composite, this can be more complicated. If you're unfamiliar with this then it may be wise to get a professional to do the job for you. They should also be able to provide you with advice on whether or not your specific door is suitable for installation of a cat flap.
If you are planning to install a cat flap into composite doors, it is important to first check with the manufacturer or a professional joiner. Any modifications made to the doors could invalidate the warranty. If you decide to do the work yourself, bear in mind that it can be a messy job and even dangerous.
When you have composite doors, you'll usually need to use a grinder or saw to cut through the door panel itself rather than simply through the GRP. Be aware that this could be extremely dangerous work and you'll have to take extreme care not to harm the door or yourself since it is extremely fragile. It's important to remember that cutting holes into any kind of glass door is far more difficult than making the same change in a uPVC or solid timber door.
