Sliding-door intent
Compare A138 and A168 through the required configuration, opening dimensions, frame relationship, and architectural sightline rather than a generic slimline label.

Atlas A138 and A168 ultra-slim aluminium sliding systems lead the UK range, supported by coordinated window and interior-door options. Project teams and potential regional partners follow separate enquiry routes.
A UK brief may use ultra-slim, slimline, or minimal-frame language. Atlas treats those as design intent, then reviews the opening schedule, configuration, frame relationship, glass, hardware, finish, and surrounding interfaces before confirming a route.
Ultra-slim aluminium sliding doors, slimline aluminium doors, and minimal-frame windows describe a visual goal rather than one interchangeable product. A138 and A168 remain distinct Atlas systems, while C75 addresses casement-window intent and the All-Aluminium Invisible Door addresses an interior opening.
A useful UK review starts with the actual opening and drawing set. Atlas does not infer installation coverage, local approval, or technical suitability from the country name alone.
Availability, documentation, and the appropriate support route are confirmed for the stated UK location, configuration, and project scope.
A138 and A168 remain the core sliding systems. C75 and the All-Aluminium Invisible Door support complementary openings, while A148 remains clearly marked Coming Soon.

Explore systemDefine the visual intent, opening type, and project information first so the discussion stays specific to the proposed architecture.
Compare A138 and A168 through the required configuration, opening dimensions, frame relationship, and architectural sightline rather than a generic slimline label.
Identify where C75 casement windows or the All-Aluminium Invisible Door belong in the same schedule instead of treating every opening as a sliding-door variant.
Provide the requirements that apply to the UK project so documentation and technical questions can be reviewed against the stated scope.
For a UK project, share plans, elevations, opening dimensions, the project stage, and finish references so the intended opening can be reviewed against the appropriate Atlas system.
UK dealers, distributors, and window-and-door businesses can introduce their region, customer focus, and technical capability for individual review, without any appointment or protected-territory promise.
Ultra-slim window profiles are only one part of a refined opening. Learn how glass, movement, thresholds, hardware, and surrounding architecture shape minimal-frame design.
buying guideUnderstand why ultra-slim aluminium sliding door costs depend on opening configuration, glass, hardware, finishes, interfaces, site conditions, and supply scope.
No. Atlas reviews each location and scope before confirming the appropriate project and support route.
Yes. Atlas welcomes suitable regional partnership enquiries and reviews each opportunity on its own merits.
Atlas reviews both routes individually. No country-wide availability, appointment, or territory outcome is assumed before that review.
