CAT & DOG FLAP INFORMATION
Panel Cut Outs
Adding any size flap into a door panel is as simple as turning up and cutting out the hole and installing the flap. If the flap is going into an existing panel, then this is a charged at £40 per cut-out and install. If a new panel is needed then I would need to get a quote for a new panel from my supplier and this would then be added to the £40 install charge.
Glass Cut Outs
Getting a cat flap hole put into a double glazed unit isn’t as straightforward as turning up and cutting out a hole. You would need to start from scratch and have a new double glazed unit made to measure with the right size cut-out. This will be a new sealed unit with the same spacerbar used for the sides of the glass around the cut-out. (see below picture)
Normally a round cut out is 215mm in diameter and needs to be 100mm from the bottom of the glass and 50mm from the sides.
PLEASE NOTE – Not all flaps are round, a square hole will cost about 4x more to put into a sealed unit than a round hole. This is because the process of having 4 corners cut into the glass makes the sealed unit weak. You can buy a mounting adapter which will hide a round hole when installing a flap that’s not round.
