Sliding bifold doors – a practical solution

Designed with attention to detail and the highest quality, the MB-86 FOLD LINE HD doors are the crowning achievement in innovative bifold systems. The sliding doors meet stringent technical requirements and can be used to create a passage with an impressive size: the maximum height of the doors can reach 3 metres, with a maximum width of 1.2 m. The central chamber, with advanced thermal breaks, improves the insulation performance of the structure.

Sliding doors are very convenient and make for an excellent choice in single-family houses. With their unique design, they can be used to install single and double glazing of various thicknesses. Thanks to such flexibility, the user can choose the standard solutions as well as options that improve noise insulation or provide enhanced protection from burglars. 

MB-86 FOLD LINE HD doors – a combination of functionality, aesthetic qualities and safety

MB-86 FOLD LINE HD doors respond to the needs of the most demanding users, who want to enjoy a beautifully integrated environment without compromising on comfort and security.

The functional hardware, designed specifically for this system, ensures the comfortable and smooth operation of the sliding doors, showcasing the attention to detail of the designers. There are many different threshold options, including thresholds with a weatherstrip or concealed seal, to match the individual needs of each user. The MB-86 FOLD LINE HD aluminium doors are a guarantee of functionality, aesthetic design and security – all combined in a single product.

Bifold doors leading outside offer their users enormous freedom, allowing them to make the most of good weather and more or less completely eliminating the barrier between a building’s interior and its surroundings. They can be used to create an excellent, expansive way out onto a patio or to link a restaurant or café with the outdoor spaces it uses seasonally.

The ALUPROF MB-86 FOLD LINE HD is a solution which provides plenty of comfort in its daily use. At the same time, it not only features high technical parameters, but also makes it possible to create large-scale structures. The bifold doors can open outwards or inwards and the panels can be configured as desired. This state-of-the-art product is designed to meet the exhaustive demands of users, architects and developers alike.

The functions and aesthetics of the MB-86 FOLD LINE HD system:

  • it has durable, three-cavity aluminium profiles, with a structural depth of 86 mm for the frame and 77 mm for the panels
  • it is available as a corner or panoramic structure and can be assembled with up to eight panels
  • the profiles for the central section are fitted with thermal breaks with a width of 24 mm for the frames and 34 mm for the panels, contributing to the structure’s high thermal performance
  • the custom-designed hardware guarantees that door panels weighing up to 120 kg can be operated with ease
  • the extensive permissible dimensions make it possible to build doors with a maximum panel height of 3000 mm and a width ranging from 700 to 1200 mm;
  • it features the widest range of threshold solutions, including one which provides a weatherstrip and another which offers a low threshold for even more user comfort
  • the glazing ranges from 13.5 to 61.5 mm, meaning that both double- and triple-glazing units can be used, as can units with increased acoustic insulation and units with a burglary-resistance rating
  • it is designed to be compatible with our renowned and highly esteemed MB-86N window and door system. The profile joints are analogous to those for the MB-86N and the two systems share some profiles, gaskets and accessories.
