The NG24 residential lift & slide door is designed to enhance modern living by creating bright, open spaces filled with natural light. It connects indoor comfort with outdoor living in a smooth and effortless way. Because of this, it is ideal for homes that want wide openings, panoramic views and a clean architectural finish.
The system allows for very large sash sizes, reaching up to 3,000 mm in width or height. Each sash can weigh up to 400 kg, yet the door still glides open with ease. This enables homeowners to enjoy expansive glass panels that maximise light and views without compromising usability.
With double or triple glazing options up to 52 mm, the NG24 offers a wide range of design and performance choices. The slim lines and large glazed areas help rooms feel more open and connected to the outdoors.
The NG24 is one of the most thermally efficient residential lift & slide doors on the market, delivering U-values as low as 0.87 W/m²K. It uses polyamide thermal breaks, foam inserts and insulated glazing to reduce heat loss. As a result, the home stays warm in winter and cool in summer.
In addition, acoustic glass options help reduce outside noise, making the system suitable for both urban settings and peaceful rural homes.
The door features precision-engineered stainless-steel bogies. These allow the sash to lift smoothly before sliding, which reduces friction and improves long-term durability. A simple turn of the handle lifts the sash for effortless movement and lowers it back into position to create a tight weather seal.
The NG24 also includes an integrated multi-point locking system for safety and ease of use. The comfort unit handle improves user experience and supports smooth daily operation.
With more than 200 RAL colours available in single or dual finishes, the NG24 can suit any architectural style. It is compatible with APA Juliet balconies and works with monorail configurations for added design flexibility.
