Aluminium French & Sliding Patio Doors
Choose between the paired opening of French doors and the space-saving movement of sliding patio doors. Aluminium frames provide a consistent look alongside aluminium windows. Share your drawings and preferred arrangement so we can quote the appropriate door configuration.
THE RANGE
Designed around the opening.
Cortizo offers hinged entrance and French-style arrangements alongside minimalist sliding systems. The right choice depends on the opening, preferred movement and the amount of uninterrupted glass required.
Tell us the appearance, operation and practical priorities for your project. We will confirm which available system and configuration is appropriate before you order.

Large-format options
COR Vision Plus is intended for larger glazed openings, with Cortizo publishing up to 94% glazed surface and manual or motorised configurations. Exact engineering limits apply.
Hinged door alternatives
Cortizo’s door family includes pedestrian, panel, pivot and bi-fold systems. For a paired hinged arrangement, the opening direction, threshold, hardware and access needs should be defined first.
ENERGY PERFORMANCE
Energy ratings explained.
Large sliding and hinged aluminium doors are dominated by glass area, so the unit specification, thermal break and threshold detail together determine the figure achieved.
Thermal break
Cortizo aluminium systems use polyamide thermal breaks between the inner and outer frame to reduce heat transfer through the metal. Frame depth and the break design vary between systems.
U-values by system
Cortizo publishes thermal, acoustic and weather-test results for specific system configurations rather than for aluminium as a whole. Deeper systems such as COR 80 are aimed at the lowest heat-loss figures.
Glass does the heavy lifting
Double or triple units, low-emissivity coatings, argon fill and warm-edge spacers usually make the largest difference. We will confirm the achievable figure for your chosen configuration.
