When it comes to creating bright, contemporary living spaces, few design features make a statement quite like large expanses of glass. Our aïr 400SS Minimal Frame Sliding Door has been designed for those who want to achieve that effortless connection between indoors and out in their home, combining ultra-slim sightlines with advanced performance benefits to enhance every aspect of modern living.
Below, we explore how our precision-engineered slimline aluminium sliding doors transform light, space and comfort within your home.
The beauty of our aïr 400SS Minimal Frame Sliding Door lies in its simplicity. With sightlines as slim as 20mm, the frame almost disappears, leaving nothing but uninterrupted glass. Whether your property overlooks a garden, courtyard or coastline, these barely-there frames allow the view to take centre stage.
This isn’t just about the finish; maximising glazing reduces the boundaries between indoors and out, bringing in more daylight and giving every room a greater sense of scale. Even compact spaces feel much more open and expansive when the architecture is built around light.
Beneath the elegant design is technology refined for real life. Each aïr 400SS door panel glides smoothly on stainless-steel rollers, carrying panes of glass up to 2 metres wide by 2.2 metres high. The result is a door that feels weightless in operation yet solid in performance.
Available in double or triple-track configurations, the system can accommodate up to six panels, allowing you to open an entire wall or create smaller, flexible openings for everyday use. Precision engineering ensures effortless movement, even after years of operation, proof that design and durability can coexist beautifully.
A home that feels bright should also feel equally comfortable. Our aïr 400SS is designed to capture as much natural light as possible while maintaining exceptional thermal efficiency. Thermally broken aluminium frames and advanced glazing deliver U-values from 1.2 W/m²K (triple-glazed), keeping warmth in during winter and excess heat out in summer.
This balance of insulation and daylight means you can enjoy the benefits of floor-to-ceiling glass without compromising on comfort or energy performance. Fewer cold spots, fewer draughts, and more natural warmth make for a home that’s efficient to run and a pleasure to live in.
It’s also a smarter choice for the environment. By optimising natural light and heat retention, minimal frame doors help reduce your reliance on artificial lighting and heating, lowering your energy consumption year after year.
Minimal frame design is often associated with contemporary architecture, but its clean lines and neutral finish make it equally at home in more traditional settings. Our aïr 400SS can be specified in any RAL colour, from classic anthracite grey and matte black for industrial interiors, to soft neutrals that suit calmer, understated schemes. Dual-colour finishes are also available, allowing you to coordinate inside and out.
Whether you’re working on a coastal retreat, an urban renovation or a countryside extension, this flexibility lets you create a door that’s tailored to your space and style.
Large panes of glass demand confidence in their construction. The aïr 400SS is built from premium aluminium that resists warping, corrosion and wear, even in exposed locations. Every system is tested to PAS 24 security standards and can be specified with multi-point locking for additional peace of mind.
It’s the reassurance that comes from knowing elegant design doesn’t mean compromise.
A great sliding door doesn’t just perform beautifully – it’s installed with precision. The aïr 400SS system has been developed to integrate seamlessly into new-build and renovation projects alike. With flexible track options, low threshold designs and bespoke configurations, installation can be tailored to suit your space and architectural layout.
For homeowners working with builders or architects, early planning ensures that structural openings, drainage and floor levels align perfectly for that sleek, flush finish the aïr range is known for. The result is a system that looks effortless because it has been designed and installed with care from the very beginning.
