Like all AluK aluminium door systems, it continues to push the industry forward by delivering unrivalled innovation, raising the bar in installation simplicity. With ever-impressive U-values of 1.4 W/m2K for double-glazed units and up to 1.0 W/m2K with triple-glazing, the Luminia SC156 offers the highest levels of thermal and acoustic performance.


Flood your home with natural light as the Luminia SC156 Lift and Slide door is expertly designed to enhance views and flood the home with natural light, providing even greater comfort.

The Luminia SC156 is visibly different by marrying style and function in complete harmony, available in multiple sliding configurations and with both mono or dual rail options.


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 1.0 W/m2K, homeowners can stay warm within their homes all year round.
