    • Hi Caroline, yes you can fit a cat flap into a PVC panelled door. Call your local glazing firms and ask them to quote you on this.

  1. Quick question: do you need a FENSA certificate if you replace an existing double glazed pane of glass with a precut cat flap hole in a double glazed pane of glass?

  2. We would like a quote for a medium sized dog flap to be fitted through double glazing door please.
