The Decalu163 Lift-and-Slide Door combines stunning minimalist sightlines with effortless operation despite accommodating individual sash weights of up to 400 kg.
Highly engineered, it means it can accommodate individual sash sizes of up to 3900mm by 3500mm and be comfortably manufactured to an opening of up to 4000mm tall by 3500mm long on a single-track option, or 4000mm by 7000mm in a twin-track configuration.
It’s available in a standard or slim interlock option and in Deceuninck Aluminium’s colour offer, including dual-colour, textured and marine-grade finishes (although we love it black!).

Space Saving Design
Unlike traditional hinged doors, sliding patio doors do not require additional space to swing open. This makes them an excellent choice for areas with limited space, providing a sleek and space-efficient solution.
Energy Efficency
Contemporary patio doors are often designed with energy-efficient features such as double or triple glazing, low-E glass, and thermal breaks. These technologies help to insulate the home, maintaining a comfortable temperature and reducing energy costs.
Increased Natural Light
The expansive glass panels of patio doors create a seamless connection between indoor and outdoor spaces. This can make the interior feel larger and more open, while also providing beautiful views of the garden, patio, or landscape. Patio doors, typically featuring large glass panels, allow an abundance of natural light to flood into the home. This not only creates a brighter, more inviting living space but also helps reduce the need for artificial lighting during the day, potentially lowering energy costs.
