Cat-Flaps fitted in glass in South West London

Cat Flaps in Glass



Small Dog-Flaps in Glass


Above are a few pictures showing microchip cat-flaps and small dog-flaps fitted in double-glazed units, white plastic infill panels and even clear perspex panels.

There are various types of cat-flaps available and they can be installed into double-glazed units, single glass or even perspex panels. Leaded or Georgian bar double-glazed units can also be manufactured to allow a cat-flap or dog-flap to be fitted.

Cat Flap installation in double glazed units

When cat-flap installation is required in a double-glazed unit, a new unit needs to be made with a hole cut. Therefore both the external and internal panes need to be made with a hole cut in each pane. The double glazed unit is then put together and sealed around the perimeter. This sealing process is also required around the hole cut for the cat-flap. The new glass unit can then be glazed and the new cat-flap installed. (The two pictures above show the hole cut and sealed, then a new microchip cat-flap fitted)

Standard cat-flaps

1st Call Glazing also stock standard cat-flaps when required, instead of the microchip cat-flap. We can supply and fit the standard four-way cat-flap, to fit through double glazed units or single panes of glass. The basic four-way cat-flap matches the hole dimensions of the microchip cat-flap. Therefore, the four-way flap could be upgraded to a microchip cat flap, at a later date if required. We also supply and fit a slim-line cat flap when needed. The slim-line cat flap requires a slightly bigger hole size than the standard four-way cat flap. Both types of cat-flap are pictures above.

*When a cat-flap is required in a single pane of glass, we always recommend a new toughened pane to be made with a hole cut. The toughened glass would look the same as the existing standard pane, however the toughened pane would be 5 times stronger than the standard single glass.

*When a cat-flap is required in a double-glazed unit, a new toughened glass unit is always supplied with a hole cut. Holes can’t be cut in existing double-glazed units.
