Install cat flap into double glazed door

Question

What are the costs and considerations involved for materials and labour to install a cat flap into a double glazed patio door which has a glass width of 400mm please?

John · Answer

Thanks for asking, it is impossible to cut a hole in a double glazed unit.

Philip Patrick · Answer

New unit would have to be made with an aperture to the cat flaps dimension, you cannot cut into your existing unit.

Jason · Answer

Hi there, unfortunatley you wont be able to cut through the glass, your best bet is to find an alterative door that you can use.

Amjad · Answer

Hi,
Not sure but I would contact a company that specialise with PVC doors as they will have to cut the glass to fit a cat flap.

Mark · Answer

Hi, 

There are more variables that you would imagine here. If you want the cat flap to go through the glass you will need to order glass with a hole already cut into it as a door will be toughened glass and you are unable to cut it. There are other options but I would need to see some photos to see if they would work in this situation.

Kind Regards,

It depends how long the glass is in the door. If it is full length, you will need a new door with a flap already fitted, or a panel in the door made of wood or plastic, to fit the flap to/in

Gary · Answer

This will cost around £80 because you will have to replace the glass unit. You cannot cut the glass as it's toughened.

Paul · Answer

Hi not advisable you need the correct cat flap or you can damage the integrity of the door

Michael · Answer

Realistically you wouldn’t want a cat flap in a glass door do you not have another door that is either solid or at least one with plastic as a filler? This would be more suitable.

Scott · Answer

The catflap is probably about £30 that would take roughly about two hours so two hours work you’re probably looking at another £30 so in total about £60

Ken · Answer

You could remove the glass and replace with PVC board and then install cat flap. Costs could be up to £200.
