MB-86 FOLD LINE HD:
The MB-86 FOLD LINE HD system is a very convenient solution in everyday use and has high technical parameters: very good thermal and acoustic insulation properties as well as tightness to water penetration and air infiltration. It allows to make structures of large dimensions. The bi-fold doors based on the MB-86 Fold Line HD system can be opened both outside and inside the building, and can have any sash configuration. It is a modern product, designed to meet the high requirements of users, architects and investors.
- 3-chamber, durable aluminium sections with a construction depth of 86 mm for frames and 77 mm for door sashes
- corner and panoramic solutions available – the structure can be assembled from 8 sashes
- the central chamber of the sections is equipped with thermal breaks (24 mm wide for frames and 34 mm wide for door sash), which translates into high thermal insulation of the structure
- specialised fittings dedicated to the MB-86 FOLD LINE HD system, guaranteeing comfortable operation of door sashes with a maximum weight of 120 kg
- large dimensions of the structure, allowing the construction of doors with a sash height of up to 3000 mm and a width of 700 to 1200 mm
- the largest number of threshold solutions, e.g. with cover sealing or convenient to use – with a hidden threshold
- a large range of glazing from 13.5 to 61.5 mm, allowing the use of both single- and double-chamber packages, including specialised ones: with increased acoustic insulation or burglary resistance
- a wide range of compatibility of the MB-86 FOLD LINE HD system construction with the MB-86N window and door system: connecting profiles as in MB-86N, as well as some sections, seals and accessories common to both systems

Frequently Asked Questions
Yes, the price may change after measurements because the window/door dimensions previously provided by the Customer will probably change. However, they are not usually the biggest cause of price changes. The changes are most often influenced by add-ons and product upgrades chosen by the Customer after measurements, such as colour changes, glazing units or accessories (e.g. silent closing, handles, electronic controls, etc.).
