Cortizo Corner Sliding Pocket Doors
Open the corner. Keep the structure clean.
Cortizo corner sliding pocket doors allow two sliding panels to meet at an open corner without a visible corner post, creating a seamless transition between inside and out.
When open, the panels slide fully into concealed wall pockets, leaving a clear, uninterrupted opening that transforms how a space connects to the garden or terrace.
When closed, slim aluminium profiles and large glass panels maintain clean sightlines and strong architectural intent.
The Fenestration Network designs and installs corner sliding pocket doors as part of considered extension and renovation projects across the UK.
What are corner sliding pocket doors?
Corner sliding pocket doors are a specialist sliding door configuration where two panels meet at a 90-degree corner.
When opened, each panel slides away into a wall pocket, removing the need for a fixed corner post.
This creates:
– A fully open corner with no visual obstruction
– Maximum connection between internal and external spaces
– Clean architectural lines when open or closed
These systems require early coordination with structure and build-up details and are not suitable for retrofitting without planning.
Design and performance
Cortizo corner sliding pocket doors are chosen for projects where design intent is non-negotiable.
Key characteristics include:
Slim interlock profiles
Large glass panels
Smooth sliding operation
Excellent thermal performance when closed
High-quality aluminium construction
These systems are typically specified for contemporary extensions, high-end refurbishments, and architectural new-builds.
Structural coordination matters
Corner sliding pocket doors do not support the building. The structure supports the doors.
We coordinate closely with builders, engineers, and architects to ensure:
Correct steel design above the opening
Accurate setting out of wall pockets
Allowance for structural movement
Correct fixing strategy at the sides of the opening
Clean integration with internal and external finishes
Without this coordination, corner systems can suffer from poor operation and long-term issues. Our process avoids that.
