Large-Format Sliding Doors with Minimal Visual Disruption

The Schüco ASS 70 HI is engineered for projects where the scale of the glazing is significant and the profile must remain as slim as possible. With a basic vent depth of just 70mm and individual vent areas of up to 9m², this aluminium sliding door system achieves a level of visual openness that few other door systems can match.

The narrow profiles allow light to flow freely into the living space, framing outdoor views with a clean, minimal aluminium surround. This makes the ASS 70 HI a particularly strong choice for projects where the architecture is designed around the relationship between inside and outside – whether in a large private home or a multi-unit residential or commercial scheme.

A High-Insulation Schüco Door System for Demanding Projects

Where thermal performance is a priority, the Schüco ASS 70 HI delivers. A whole-window U-value below 1.3 W/m²K – achieved through polyamide thermal breaks and high-performance glazing – makes this one of the strongest performing aluminium sliding systems in its class. Sound insulation of up to Rw 44 dB further broadens its appeal for projects in acoustically sensitive locations.

The system’s flexible designs extend to a full variety of design options, including single, double, and triple-track configurations, dual-colour powder coat finishes, and glass thicknesses from 24 to 52 mm. From high-end homeowners seeking a refined glazing solution to architects specifying for complex commercial projects, the Schüco ASS 70 HI offers the range and reliability to deliver.
