MB-86 Fold Line HD Bifold door System

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.

• 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

• 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
