Sliding door systems, and aluminium patio systems in particular, fully reflect current trends in window construction: these large glazed surfaces are easy to operate and open up the space, allowing it to connect seamlessly with its surroundings. As entrance systems, they provide excellent solutions that make you feel almost unrestricted when entering a building – it is as if an entire wall could simply be moved to the side.
But which system should you choose? There are so many – and, in fact, the wide range of available systems allows you to choose a solution that can be fully tailored to the requirements of a specific project and its future users. Fenbro Sales Experts are thoroughly familiar with the possibilities offered by aluminium sliding systems and are, of course, ready to assist you. If you are looking for an in-depth and detailed summary of the features of all the options, this article is the right first step, as it brings together all the key information in one place.

Aluprof MB-59HS: Lightweight and flexible
The Aluprof MB-59HS system is one of the lightest sliding systems in our range. With its lightweight frames and the option of using a low aluminium profile, the system impresses with its light appearance and fits perfectly with current design trends.
The Aluprof MB-59HS lift-and-slide system is based on the belief that a lift-and-slide system does not have to look heavy. It allows the creation of large sashes that remain lightweight and easy to operate. With a maximum sash width of 3.3 m and a sash height of 2.8 m, it can also accommodate oversized openings. The system is available in two versions: ST, with less insulation, and HI, with additional insulation in the profile for improved energy efficiency.
Applications: Aluprof MB-59HS works perfectly as a door connecting a room or conservatory with a patio. Its structural properties make it suitable for use in both residential buildings and, for example, hotels.
Projects: One example is this impressive project in Cork, Ireland, where two MB-59HS systems can be seen. Another attractive example of the model can be found in this construction project in Longford.
Aluprof MB-59HS Monorail: Slim and elegant
The Aluprof MB-59HS Monorail system is a version of the ‘classic’ MB-59HS with a single track along which the sash moves. Thanks to its single guide rail and the narrow sash interlock, the system has a modern appearance and allows more light into the room. The fixed section is slimmer and the entire system looks lighter.
At the same time, there are practically no limitations compared with the classic version in terms of dimensions or sash weight. The main difference is that the Monorail version does not offer an opening scheme with two movable sashes, as its single-track design makes this impossible.
Choosing the simpler and smaller Monorail version therefore offers the user several benefits. Because the system has only one guide rail, both the entire system and the sash frames are slimmer, allowing more sunlight into the room.
Applications: The slim Aluprof MB-59HS Monorail demonstrates its modern form in smaller rooms and wherever the aim is to achieve a glass-wall effect.
Projects: This new-build project in Tipperary shows how attractive the lightweight construction of the MB-59HS Monorail can look. This renovation project in Kildare also clearly shows the difference between the MB-59HS Monorail and French doors.
Aluprof MB-77HS: Robust and versatile
The Aluprof MB-77HS aluminium sliding system offers outstanding capabilities, while its strength and performance make it almost unique. With a maximum overall construction width of more than six metres, such a system is truly impressive, yet it can quite literally be moved to the side with a simple movement of one hand.
A system based on the MB-77HS profile provides excellent protection, thermal insulation and sound insulation. Its two- or three-track construction allows for different opening schemes, including configurations with as many as three or four movable sashes. The system provides virtually unlimited design freedom. With a maximum sash height of more than three metres, it can be used to create futuristic sliding systems.
The MB-77HS system is considerably more advanced than the MB-59HS and includes a wide range of components and solutions. It can also be used to create systems that do not necessarily run in a straight line. This means that a single installation can form a consistent system in which the individual sashes are arranged at right angles to one another. This gives architects a broad range of possibilities.
Applications: Modern patio systems for both innovative villas and future-ready office building façades.
Projects: An example of this system in use can be found in this new-build project in Kildare. Another example is this unique property in the West Midlands, England – what a design!
Aluprof MB-77HS Monorail: Strong and beautiful
The Aluprof MB-77HS Monorail is the single-track version of the ‘large’ MB-77HS system. There are no other differences compared with the alternative construction, apart from the maximum dimensions and weight values, which are technically lower for this version.
The MB-77HS Monorail offers excellent thermal insulation while still looking lightweight thanks to its large glazed surface, bringing unique, modern elegance to a project. The high-quality construction of the system and its attention to detail make it a solution for demanding construction projects.
One limitation compared with the main version is that, because there is only one track instead of two or three, the movable sections cannot slide over one another. Apart from opening schemes that require two movable sashes to overlap, the other options remain available.
Applications: Modern architecture, patio systems in cutting-edge homes and large sliding systems for demanding projects.
Projects: This project in Wexford shows the Aluprof MB-77HS Monorail sliding system being used to excellent effect. In this other new-build project in Waterford, we can see a truly unique installation.
Reynaers MasterPatio: No limitations
The Reynaers MasterPatio system is unique in many aspects. Although it may be a conventional sliding door, it incorporates a range of high-quality solutions that make every MasterPatio installation something special. Let us take a closer look at the features of the system.
The first thing you notice about the Reynaers MasterPatio system is that it accommodates the thickest glazing of all the products in our comparison. A glazing unit of 62 mm means that a great deal can be expected in terms of thermal and acoustic insulation. The unique construction and strength of both the fixed and movable sections mean that they can be very large. With a maximum height of three and a half metres, it is easy to imagine the exceptional spaces in which this system could be installed.
At the same time, the sashes move effortlessly to allow people to pass through. When closed, the system also achieves very good wind and watertightness values, ensuring peace and comfort in the home at all times.
Applications: Cutting-edge buildings and large passageways where no compromises are to be made.
Projects: The MasterPatio system is being used for this renovation project in Sligo – and one can see just how elegant and balanced the installation looks.

Frequently Asked Questions (FAQ)
Which aluminium sliding door system should I choose?
The best system for you is one that meets all your technical, design and aesthetic requirements while also making economic sense. Depending on your needs, the building conditions and the relevant requirements, Fenbro Sales Experts will help you find exactly the right solution.
What are the main differences between the individual sliding doors?
The main differences between sliding doors lie in the permitted width and height of the entire system. In short, to allow as much light as possible into a room, you should not necessarily choose the system that can achieve the largest dimensions, but the one that best meets your own needs.
Which aluminium sliding systems are easier to design and maintain?
Monorail systems are simpler because they generally have one guide rail instead of two or three, meaning that the overall system has fewer moving parts. The fact that there is only one track also means there is less to clean.
What are the advantages of aluminium sliding systems with two or three guide rails?
The MB-59HS and MB-77HS systems allow larger installations to be created, in which several sashes can be slid to the side and over one another to create a truly wide passageway.
Is a low aluminium threshold available for aluminium sliding systems?
The option of using a low aluminium threshold depends on the specific configuration and should always be discussed with a Fenbro Sales Expert.
