Made To Measure Cat Flap Glass
Installing a cat flap in glass doors requires specialist manufacturing. The aperture must be cut before the glass is toughened, as existing glass panels cannot be modified after production.
At Stevenage Glass, we manufacture bespoke toughened glass units with precision cat flap cut-outs, factory-sealed and air-vacuumed to maintain thermal performance.
How Our Cat Flap Glass Service Works
We replace your existing glass panel with a new toughened unit featuring a precise aperture for your cat flap installation.
Supply options:
- Provide your own cat flap and we’ll manufacture the glass to fit its dimensions
- We can supply the cat flap unit for you
Each replacement unit is manufactured to your exact measurements and toughened to meet safety standards.
Patio Doors & Bi-Fold Doors
The majority of cat flap installations occur in patio doors and bi-fold door systems. Due to their low-level positioning within human impact zones, these applications legally require toughened safety glass.
Our manufacturing process ensures:
- Precise aperture positioning for your specific door configuration
- Correct glass thickness matching your existing unit
- Full toughening to BS EN 12150 safety standards
- Factory edge finishing around the cat flap opening
- Air-vacuumed sealed units to prevent condensation

Q: Do you offer a delivery and fitting service for glass products?
Yes, we offer a delivery and fitting service. Please see our map for further details on the areas we deliver to.
