S140 Lift and Slide Door
Why Choose Our AluK S140 Sliding Doors?
Create your dream living spaces with the excellent zone-creating benefits of sliding doors. Sliding open horizontally either parallel to or within walls, sliding doors are a great space-saving tool for living spaces. Open up rooms with fresh air and stunning lighting, or enjoy outdoor views from the comfort of your home all year round.
- A modern choice: Offering both extraordinary performance and contemporary aesthetics, our sliding doors offer one of the most modern and innovative designs. Manufactured to the highest UK standards, these doors provide high levels of thermal and acoustic insulation along with market-leading water tightness for performance time and time again.
- A customisable choice: In addition to dual and triple rail options, a comprehensive range of colours and anodised finishes are available for our sliding door systems. Whichever sliding configuration you pick, they are available in single and dual colours as well as anodised finishes, accompanied by a stunning range of hardware.
- A versatile choice: Flood your home with natural light, as our sliding doors are the ideal solution for bringing natural light and comfort into your home. The system's wide range of configurations makes it fit for every purpose and even offers Doc L-compliant U-values for refurbishment & newly built properties.
Streamlined Contemporary Aesthetics
Modern, versatile and customisable, the S140 Lift & Slide Door combines high performance with contemporary design to provide a reliable aluminium door system for almost any architectural project.
Create your slider your way with our wide range of frame and sliding styles, including track, panel and glazing options. Make a real statement with our AluK Collection, specifically designed to bring you the latest in colour and textured finishes that give your home that extra level of personalisation.
The S140 also offers beautiful aesthetics with a flush frame to sash sightline. Thanks to some clever construction, it gives the appearance of more glass and less frame, which is a key driver in sliding door purchases.
SOFT CLOSE & HYPER EFFICIENT
Homeowners can benefit from an upgraded soft close system. Not only does this enhance the premium feel of the door itself, but it acts as a safety device. Stopping it from closing too quickly and trapping fingers.
The S140 is available in both dual and triple-track options, with a two-part triple-track profile. Some clever engineering enhancements help simplify and speed up the fabrication process.
Their revolutionary ultra-smooth rollers even self-level to any minor shifts in the frame installation. There are three-wheel and five-wheel rollers available depending on the weight of the sash, and just two are required per sash. Allowing for a much quicker and hassle-free installation every time.
Extraordinary Performance
The system’s high level of thermal and acoustic insulation, along with its market-leading water tightness and wide range of configurations, makes it fit for every purpose. Offering U-values as low as 1.1 W/m2K, homeowners can stay warm within their homes all year round.
Your comfort and security are our top priority, so we test our doors to the highest degree and performance standards. Meeting Class 4 (600Pa) air tightness, Class 6A (250Pa) water tightness and Class C3 (1200 Pa) wind load, you’ll notice the visible difference from your old sliding door or the boost our doors offer your new space.
