Our products
Tilt and turn windows and doors
Thanks to the concealed sashs and the slenderness of the profiles, K·LINE windows offer a glazed surface area 20% larger than a traditional window. With their neat and discreet aesthetics, the decorative K·LINE windows make the most of the elegance of aluminium to participate in the interior and exterior harmony of the building. They are also ideal for renovations, as they preserve the original appearance and at the same time provide maximum natural light.
2-Track sliding glass patio doors
A new standard of light and comfort
The K·LINE double-track sliding patio door is the ultimate light window, with its wide opening to the outside, which provides maximum natural light to your home. K·LINE offers you a new aluminium sliding door with exceptional performance, combined with slenderness and contemporary design.
3-Track sliding glass patio doors
Light in panoramic format
Do you dream of new views of the outside? The K·LINE triple track sliding door opens up new perspectives on the outside and floods your home with natural light. Imagine a 6.80 m wide, high-performance panoramic opening onto your terrace and garden.
Embedded frame sliding glass doors
Minimalism at its best
Its greater glazing and use of the essential profiles with the frame recessed in the wall, allow a greater vision and maximum use of the entry of sunlight, although it continues to provide exceptional performance with the highest levels of watertightness, and its sash and frame profiles without bimetal effect make it easy to use in all conditions.
Hidden pocket sliding door
A complete opening to the outside
The sash is concealed between the partition walls until it disappears completely. Where does the outside begin and the inside end? "If space, light and freedom of movement are the most important things for you, the hidden pocket sliding door is made for you! "
Minima slide - Wide-span sliding glazed door - New!
The minimum manifestation of a window
The most modern interpretation of a window, integrating with the architecture and the landscape. The use of the minimum components that make up a window with the fixed elements embedded in the walls, allows maximum glazing, facilitating a full view of the outside.
Lift & slide door

Simplicity of use and high performance, a perfect combination of functionality with high thermal and acoustic insulation, which will bring comfort and energy savings to your home. Thanks to the lower guide profile that is almost completely embedded in the floor, obstacles between indoors and outdoors are largely eliminated.
