On ships, horizontal sliding doors are often chosen for openings between the exterior and interior. These sliding doors are space-efficient and create a minimalist connection between the outdoor environment and indoor spaces.

This is achieved through the MethermoXL system, a sustainable Dutch design that emphasizes minimal profile use and maximum glass surface area. Additionally, sliding windows are also installed on ships. These windows, equipped with the MethermoXL system, feature a maximum glass surface area. They are easy to operate and particularly space-efficient on a ship.
