Our projects

Sliding doors with excellent technical specifications

Our aluminium doors are not just regular structural members. MB-SKYLINE TYPE R doors use slim profiles to ensure a unique, panoramic view of your surroundings. They offer high thermal performance and noise insulation and are resistant to weather conditions. They are also strong, durable and easy to use. The maximum height of the door can be up to 4 metres, with a maximum weight of up to 1.2 tons, letting you design an exterior door of a truly impressive size.

The sliding doors are also equipped with a modern drainage system, system brackets with adjustable height, a structural base with high thermal insulation and the “zero mullion” system to enable the use of sun shades on the outside.

MB-SKYLINE TYPE R – panoramic doors with a concealed frame

The MB-SKYLINE TYPE R doors are a combination of functionality with a designer-style look. One of the important advantages of sliding doors are the slim profiles, which increase the glazed area to let you enjoy a panoramic view of the outside space. The specific features of this solution are fully concealed profiles and narrow mullions, which enhance the value of the building by giving it a unique style. MB-SKYLINE TYPE R doors come in many different colours and finishes to match your taste and the look of the exterior of the building. 

Choose MB-SKYLINE TYPE R sliding doors to enjoy a combination of functionality and design in every aspect! Choose a modern solution to ensure comfort and unforgettable visual qualities.

The ALUPROF MB-SKYLINE TYPE R is a cutting-edge, large-scale, sliding door system which makes a feature of lightness and aesthetics. Slender profiles simultaneously provide both a contemporary look and a panoramic view of the surroundings.

The main features of the MB-SKYLINE TYPE R are the completely invisible profile of the door panel, the slender mullion and the shallow frame, all of which will be appreciated by users at the very first glance. The panels may be massive, but no great effort is required to slide them open and closed and the mechanism that operates them is almost soundless. The maximum height for a structure based on the system is a soaring four metres and, if a concealed motor is fitted on the outside rather than being hidden, then the moving panel can weigh as much as 1200 kilograms. This affords the possibility of designing spectacular glass walls. Doors created using the MB-SKYLINE TYPE R give a building an exceptional style and enhance the status of an entire development.
