Bifold MB-86 FOLDLINE Aluminium doors

External folding doors are a versatile and practical solution for homeowners who want to maximize their living space and enjoy more freedom in how they use their homes. Unlike traditional doors, external folding doors consist of multiple panels that fold and slide along a track, allowing users to create a large opening that seamlessly connects indoor and outdoor spaces.

Features and benefits of the MB-86 FOLD LINE system

  • corner and panoramic solutions available – the possibility of assembling a structure of up to 8 panels
  • durable and stable construction due to high quality aluminium profiles
  • possibility of creating aesthetically pleasing and modern large glazings at the same time providing the opportunity to use the space of the building very effectively thanks to the optimal design of the system.
  • freedom of arrangement of the system that allows its use in various types of buildings.
  • folding doors can be opened both outwards and inwards and can have any wing configuration.
  • the possibility of fully customising the structure and adapting it to current architectural trends thanks to a wide range of colours (ral).

Functionality

Folding doors are the ideal solution for conservatories, terraces or restaurants. The way and direction in which the wings fold (inwards and outwards) can be adjusted to suit your needs. When all the wings are open, you get a very large open space, that is a perfect connection between the house and the rest of the surroundings. The biggest advantage of folding doors is that the wings can be folded down to create one, coherent open space. Doors can be produced up to 6 metres wide. When designing the door opening pattern please ensure that the leaves do not exceed a width of 930mm. The door leaves can be folded to either side. One of the leaves can be fitted with a handle and lock on both sides, allowing the folding door to be used as an additional entrance to a conservatory, house or restaurant.

Thermal insulation

Folding doors are constructed using a 3-chamber system with thermally insulated profiles. The doors can be fitted with a double or triple glazing packs. All glazing and seals are made of EPDM synthetic rubber.

standard threshold

This is the most common type of threshold used in our folding doors. It can be used in most building situations.

Low threshold

If the site conditions allow and you wish to create one level floor between the inside of the house and the terrace, a low threshold can be used. When opened, it provides a smooth transition with virtually no barriers.

In some situations it may be worth using an additional gutter with a drainage.

Bifold on existing floor

If it is necessary to install a bifold door on an existing floor, it is possible to use this type of threshold.

Glazing

Standard glazing package

Standard glazing package
Our doors are equipped with a tripe plane glass that is connected by three spacing frames, two of which are covered with Low-E coatings

The glass type strongly depends on the measurements of the whole door configuration. Please have a look at examples:

  • 4LE/18Ar/4/18Ar/4LE
  • 4th/16Ar/4/16Ar/4th

 

Safety glass

For an extra charge we have in our offer a safety glass option.

The safety glass consists of two glass panes joined together with a laminated PVB foil. This solution is used in for instance the windscreens of passenger cars because of its shatterproof function and strength. Additionally, it provides better sound insulation.

Sample glass package with a safety glass:

  • VSG 33.1 LE/ 18 Ar/4mm/18 Ar/4mm LE
P4 glass – increased resistance to damage / burglary

P4 glass type with higher resistance to damage e.g. VSG 44.4 where glass panes are connected with 4 layers of protective foils.

The strength of P4 glass is confirmed in laboratory tests. During the tests, the glass must withstand a three-time impact with a 4.11 kg steel ball dropped from a height of 9 m. This type of glass is characterised by the highest resistance to manual attack for instance with a hammer weighing several kilograms.

Sample package with a safety glass:

  • VSG 44.4 LE/ 16Ar/ 4mm/ 16Ar/ 4mm LE
Warm spacer frames

A spacer frame is the basic element of joining the space between the panes in a glass. It is normally filled with 90% argon which is a non-toxic, insulating dense type of gas and 10% air. It allows to obtain a heat transfer coefficient of up to Ug = 0.4 W/m²K.

Warm, Swisspacer Ultimate spacers (available in 6 colors) are used as standard in our glazed units. They are recommended for energy-saving construction thanks to a significant reduction in the heat transfer coefficient. Due to the extremely thin gaps between the panes Krypton is used which is a gas that performs best as an insulator when used in such configurations.

 

There is a huge range of choices in glazing, for instance: energy-saving, sound-absorbing, safety, anti-burglary and solar glass.

Solar glass
This category includes several types of special-purpose glazing designed to reduce the effect of the sun in interiors – both in terms of heat transfer and excessive light penetration. The most common solutions are milk glass, glass with one-way mirror effect as well as bronze reflex glass.

 

Thermal insulating glass – energy efficient
This type of glazing is designed to provide the best possible thermal insulation of a room, which is especially important in temperate climates, where there are significant temperature differences between seasons. Thermal insulating glazing is covered with an extremely thin layer of precious metals, so in winter it minimizes heat loss from the room, while in summer it prevents excessive heating.

Sound-absorbing glazing
Sound-absorbing glazing provides excellent sound insulation along with comfort for people in rooms whose windows face, for example, busy streets (low-frequency sounds) or children’s playgrounds (high-frequency sounds). The effect of sound-absorbing glass is related to the thickness of the glass – the thicker the glass, the better it protects against outside noise. Such glazing can be made of ordinary glass, tempered glass or laminated glass with a film. The space between the layers of glass is filled with heavy gases.

Safety glass
Safety glass is usually layered glass or glass made of laminated or tempered glass that does not shatter into small fragments when broken. This type of glazing primarily provides protection against injury from glass shards.

Anti-burglary glass
Burglar-proof glass, as the name suggests, protects windows from a burglary. Mostly they are layered glass, made of two layers of glass and between 2 to 4 layers of PVB film. The film strengthens the structure of the glass – the more layers of film, the more resistant the glass is to mechanical damage. We can divide anti-burglary glass into 8 classes: P1A, P2A, P3A, P4A, P5A, P6B, P7B and P8B. The strength of glazing in each class varies significantly. For example, according to the standard, glazing of the P3A class can replace the grid made of Ø10 steel wire, with meshes up to 150 mm, while glazing of the P8B class replaces the grid made of steel bars with diameters up to Ø16.
