The NG24 lift & slide door combines strong thermal performance, smooth movement and a modern design. It supports double or triple glazing and can handle sash sizes up to 3000 mm wide or high, with a maximum weight of 400 kg. This makes it ideal for large openings and bright interior spaces.
The door reaches thermal values as low as 0.87 W/m²K. This level of performance comes from its advanced polyamide thermal breaks and insulating foam. When used with high-performance glazing up to 52 mm, the system helps lower heat loss and improve energy efficiency in both homes and commercial buildings.

The frame design and acoustic glass work together to reduce outside noise. As a result, the lift & slide door suits projects near busy areas where sound reduction is important.
Stainless steel bogies allow the sash to lift and slide with very little effort. When the sash lowers, it creates a firm weather seal that reduces air leakage. The integrated multi-point locking system adds security and is easy to adjust when needed
The system can support very large sash sizes. This makes it perfect for enclosing wide spaces while keeping strong views and high levels of natural light. Pull handles, finger pulls and a comfort unit help ensure smooth and simple operation.
The NG24 lift & slide door is available in single or dual colour. More than 200 RAL colours are available. The system runs on a monorail track and can be paired with the APA Juliet balcony for added design options. Multiple layout configurations are also available.
