It is essential to take measurements of the door to ensure you get the correct size cat flap. There are many sizes available. This ensures you get the correct size that fits into your upvc door, otherwise, it might be too small or too large and your cat will be unable to use it.
Before you take any action, though, take a ruler and take measurements of the length of the door in various places along its edge. Also, you should determine the door's height in a few places. A door that is too high will cause your cat to do an exercise routine every time it uses the flap.
If you're unsure of how to measure the door, it may be best to ask for assistance from a glazier, or someone who performs this type of work often. They'll be able to determine whether your door is suitable for cat flaps, and will advise you on what size flap to buy.
When you've got your measurements, the next step to do is to mark the shape of the hole in the door. This will give you an outline to cutting the hole and will stop you from making a mistake that could cost you money in the long run!
You must also ensure that the hole you're creating 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, since this could cause leakage and damage to the seal.
If you have a glass door you could want to let this job to a professional glazier. It can be difficult to fit a cat-flap into an existing pane. It is also possible that it cracks and loses its weatherproof seal.
Measure the Cat
A cat flap lets your pet leave and come back whenever they want without you having to leave him on his own. It can also prevent draughts entering your home, which isn't good for you or your cat.
If you do have a uPVC or composite door it could be a challenge to put in a cat flap. These types of doors are typically made of different materials than traditional wooden or uPVC doors, and the installation process is quite different too. Before you decide to install an egress flap to your uPVC or composite door, be sure that it's compatible and you have checked with the manufacturer because alterations could affect any warranties.
These doors are generally designed to last and are tough and have insulation. They are more resistant to weather than other kinds of doors, but it can be difficult to install an animal flap. Consult a professional before installing a cat flap onto a uPVC door or composite.
To make sure that your cat can pass through the door, you'll have to measure their height. It is easiest to measure their height when they are at peace or asleep, which means they don't move around. Once cat flap insulation have their height you can measure the distance between their stomachs and the floor to determine the location of the flap's bottom. Then, you can mark this spot on the door.
When you use power tools to cut your uPVC or composite door, you have to be careful. Drilling into metal can cause cracks, especially if the area is composed of toughened glass. This is why it's highly advisable to hire an expert glazier to install your cat flap into a pane of glass. This will prevent the glass from shattering or becoming brittle. A glazier will also be able to provide you with a cat flap hole that is less likely to break and is safer for your cat to use.
Cut the Hole
If not, you can make one yourself with a sheet of paper (tracing paper is the best choice). If it doesn't, you could create your own using a thin sheet of paper (tracing papers are great). Once the shape has been pencilled in on the door, then use your spirit level to ensure that the shape is horizontal. This will allow the cat flap to properly fit into the door and prevent it from being in a position to slide open or close.
Then, employ a jigsaw for cutting out the design that is on the door. Make sure you are using a blade that is suitable for use on uPVC doors. Usually, it will be marked as such however, if not, ask the staff at your DIY store for assistance. Once you have the hole made and the flap section is in place, put it against it and push it out to ensure that the action of the flap is smooth. If it is bound at any point, you can use a filer or rasp to fix this.
You should also check whether there are any electric gas or cable lines within the door you will be cutting through, because they could be damaged by your Jigsaw. Also, be aware of any handles or other fixtures on the door which will need to be removed in order to install the cat flap. Be careful not to scratch these objects in the process.
Most people who install a cat flap on their own will have an ordinary solid uPVC door and so will not be dealing with any of these issues. However, if your door is made of timber or has decorative panels that cannot be removed then this will increase the difficulty of the task.
For these types of jobs, it is worth getting expert guidance from a cat-flap fitting expert. It is crucial to do them correctly to avoid problems in the future. Making the wrong choice could result in the door becoming damaged and may cause the warranty to be invalidated.
Place the Flap
Once you've made your hole, you can place the flap to check whether it opens and fits. If you spot any areas that catch or stick, use a hand file or sandpaper, to file them down until they fit perfectly and can be opened without issue. Make sure that the flap is flush with the door too.
If your tool doesn't have a template, you can make use of thin paper such as tracing or acetate. Place the paper against the door and draw a line where you want to position the flap (this will serve as your cutting guide). Draw four screw holes on every corner of the flap with the pencil marks you traced on the door. These will be the screw points that you'll need to use to fix the flap to the door.
Most uPVC doors are strong and therefore quite straightforward to cut into. But, if your door is made from GRP or a composite material, it can be more challenging. If you're not familiar in this area, it might be beneficial to engage an expert to complete the job for you. They should also be able to provide you with advice on whether or not your door is suitable for installation of a cat flap.
You can install an opening for a cat flap in composite doors but it's important to check with the manufacturers or a professional joiner prior to making any changes as any alterations to these doors could invalidate the warranty. If you choose to carry out the work yourself, remember that it can be a messy and potentially dangerous job.
You'll require a grinder or saw to cut through composite doors more than just the GRP. Be aware that this could be very dangerous and you'll have to take extreme care not to damage the door or yourself as it is very fragile. It's worth noting that it's more difficult to cut the door glass than it is for a uPVC door or solid wood door.
