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.
Pocket detailing and finishes
The success of a pocket sliding door system depends on what you don’t see.
We plan:
Pocket depths and wall thickness
Internal lining and finishing details
External junctions and weathering
Drainage and threshold build-ups
These details are confirmed before manufacture, not improvised during installation.
Threshold options
Threshold detailing is agreed at design stage and coordinated with finished floor levels.
Options typically include:
– Standard low thresholds
– Partially recessed thresholds
– Flush thresholds where drainage and build-up allow
Flush thresholds are only recommended where external drainage and internal floor levels are designed accordingly.
Is a corner sliding pocket door right for your project?
Corner pocket systems are best suited to projects where:
Structure can be designed around the opening
Wall pockets can be formed from the outset
Build tolerances are controlled
Design priority outweighs speed or cost
If these conditions aren’t met, we’ll advise on alternative configurations that achieve a similar visual result with fewer constraints.
