Cat Flap Fitting in Composite Doors
Composite doors vary in construction, so a proposed cat-flap opening needs a model-specific assessment.

Cat Flap Fitting in Composite Doors — review composite construction before cutting an opening, with site access, working hours and protection requirements planned, with the surrounding frame, fittings and opening condition checked.
The door's internal structure, locking area and manufacturer's instructions determine whether modification is appropriate. Adjacent glazing or another route may be worth considering when the leaf cannot be altered suitably.
The detail that matters
Could the alteration affect my warranty?
Yes. Obtain the relevant manufacturer's position on the proposed change before authorising the opening.

What should I include in this enquiry?
Send the exact flap model and photographs of the proposed position from both sides. Include the postcode, the pet size and details of the panel, glazing or wall through which the opening is planned.
