Alumil sliding doors represent a significant step forward in what you can expect from aluminium doors in the UK. These systems are engineered for large glass areas, slim visible aluminium, and high levels of comfort, security and reliability. Designed for modern homes, premium developments and demanding commercial projects, they combine architectural styling with the kind of internal engineering usually reserved for flagship façade systems.
From practical, minimal sliding doors for everyday family use to large-span lift-and-slide systems and ultra-minimal designs with concealed frames, the Alumil sliding doors range covers almost every sliding door requirement. What they all share is the same design philosophy: effortless operation, carefully controlled sightlines, advanced thermal performance and proven reliability in some of the most challenging environments worldwide.
SUPREME S700 Sliding Door
SUPREME S700 is Alumil’s top-of-the-line lift-and-slide or inline door, designed for very large openings and high-specification projects. It has been developed for wide spans, tall doors and large glass areas where you want maximum light and views without compromising usability or performance. With sash weights up to 600kg, it comfortably handles doors that would be beyond the limits of many standard systems.
The system combines a narrow interlock of just 47mm with excellent thermal and acoustic performance, watertightness and wind resistance. Low thresholds, smooth-running lift-and-slide hardware and the option for automated operation mean that even very large doors can be opened and closed with minimal effort. The Eclipse variant allows the bottom frame to be concealed and finished level with the floor, supporting fully flush transitions and “transparent” architecture.
With multi-track options, pockets and corner designs, SUPREME S700 is suited to premium homes, high-rise apartments and commercial schemes where a sliding door must look and feel like a piece of architectural glazing rather than a standard patio door.
SUPREME S500 PHOS Sliding Door
SUPREME S500 PHOS takes minimal sliding doors into more advanced territory. It combines very slim lines and concealed framing with a carefully engineered insulated structure, giving high levels of thermal performance and acoustic comfort without sacrificing the minimal aesthetic. The interlock can be as narrow as 25mm, ensuring views and daylight take priority.
Where the system really stands out is in the SlideAir variant, which uses Alumil’s patented magnetic levitation technology. This allows extremely heavy sashes (up to 1000kg) to slide with very low effort, without the need for motors or external power. For users, the door feels surprisingly light and controlled, even at very large sizes.
Eclipse and Total Eclipse versions make it possible to conceal the bottom track under the floor finish and hide the head and jambs within surrounding finishes. The result is a door that appears as pure glass, with minimal visible structure, suited to high-end residential and hospitality projects where detail and finish are critical.
SMARTIA M630 PHOS Sliding Door
SMARTIA M630 PHOS is a thermally insulated minimal sliding system designed for contemporary homes that favour clean lines and generous glass areas. Following a “less is more” approach, the outer frames can be built into surrounding construction so that only the slim meeting section and glass remain visible, giving a calm, modern appearance inside and out.
The system supports double or triple glazing up to 32mm, with polyamide and thermoplastic insulation helping to deliver strong thermal performance, good acoustic reduction and reliable weather protection. Despite the minimal design, M630 PHOS handles sash weights up to 250kg, ensuring flexibility for larger openings and heavier glass specifications.
A wide variety of typologies are available, including standard sliders, multi-panel arrangements, pockets and corner designs, with options for fixed lights and discreet flyscreen integration. For homeowners and designers who want minimalist sliding doors with practical performance and everyday usability, SMARTIA M630 PHOS offers a well-balanced solution.
SMARTIA M450 Sliding Door
SMARTIA M450 is Alumil’s next-generation sliding and lift-and-slide system for modern homes. It is built around a 45mm sash depth and engineered to keep visible aluminium to a minimum, with an interlock of just 25mm. This gives the door a light, open feel while maintaining the strength and performance needed for everyday use in UK properties.
Thermally insulated with advanced polyamides and clever use of PVC profiles around the frame, M450 delivers very good energy performance, controlled condensation risk and smooth day-to-day operation. The frame is designed to be easy to clean, with invisible water drainage and reduced visible depth, making it as practical as it is attractive.
Available in sliding and lift-and-slide configurations, with options for multi-panel layouts, flyscreens, pockets and meeting stiles, SMARTIA M450 is ideal for replacements as well as new builds where a slim, reliable, well-priced sliding door is required.
Why Choose Alumil Sliding Doors?
Alumil sliding doors are sophisticated systems developed over decades and proven in many different climates. They combine slim sightlines with high levels of insulation, security and weather resistance, while keeping day-to-day operation intuitive and light. Every detail is considered, from how the frame sits within the floor and walls, to how the handle feels in the hand and how quietly the sashes run on the track.
These doors are widely used in homes, hotels, premium residences and high-rise apartment buildings, where safety, reliability and long service life are non-negotiable. For the UK market, they offer an alternative to standard sliding and lift-and-slide systems: more architectural in appearance, more advanced in design and more flexible in application.
For Fabricators
For fabricators, Alumil sliding doors provide a route into higher-value, design-led projects without abandoning practical fabrication considerations. The systems use familiar principles and tooling, with well-thought-out drainage, insulation and hardware interfaces that support efficient production and consistent quality. Certified performance data and a clear typology range help with specification and documentation.
Because these doors are not widely manufactured in the UK compared to more common brands, they offer a way to differentiate your product offering. You can supply sliding, lift-and-slide and ultra-minimal systems that stand apart in terms of appearance, performance and capability, opening up opportunities with architects, premium installers and project-led customers.
For Installers and Showrooms
For installers and showrooms, Alumil sliding doors offer a strong way to stand out in a crowded market. The visual difference is immediately obvious: slimmer meeting sections, more glass, modern lines and carefully finished details at the threshold and frame edges. This makes them attractive centrepieces in a showroom and compelling options for clients comparing alternatives.
On site, the systems are designed with installation and adjustment in mind, with robust hardware, thoughtful drainage details and configurations that can be tailored to each project. The ability to offer everything from practical M450 sliders to large-span S700 lift-and-slide doors, and minimal S500/M630 PHOS systems, helps installers meet a wide range of briefs without resorting to ad hoc or one-off solutions. For businesses building a reputation around quality and design, Alumil sliding doors provide the right tools to support that positioning.
For Homeowners
For homeowners, Alumil sliding doors offer a way to bring more light, space and openness into the home while maintaining comfort and security. The slim profiles, minimal interlocks and large glass areas help connect interiors with gardens, terraces and views, making rooms feel larger and brighter. At the same time, advanced insulation, carefully engineered sealing and high-spec hardware keep draughts, noise and heat loss under control.
Operation is smooth and reassuring, even on larger doors, and there are options for fully flush thresholds and concealed frames that suit modern extensions and open-plan spaces. For anyone upgrading from older patio doors or choosing sliding doors for a new build, Alumil provides a noticeably more refined and capable alternative.
For Architects and Designers
Architects benefit from sliding systems that combine controlled, minimal sightlines with a broad range of typologies and sizes. The Alumil range allows you to work with large openings, tall sashes and complex layouts such as pockets and corners, while still meeting performance requirements for U-values, air and water tightness and wind load resistance.
Options such as concealed frames, flush thresholds, narrow interlocks and, in the case of S500 PHOS, magnetic levitation technology, make it possible to design doors that sit comfortably alongside high-end curtain walling and façade solutions. The systems have been developed with flexibility in mind, supporting both residential and commercial specifications and integrating cleanly with modern interior and exterior finishes.
