Muntin-Free MB-78EI Walls

119.1_MB-78EI

Aluprof offers the  MB-78EI system-based transparent, fire-rated wall solution, the so-called muntin-free walls. This allows for the construction of internal partitions walls without the visible vertical wall profiles that separate the individual modules of the wall, while preserving their full fire resistance. The joint between the glass panes is only 4 mm and is filled with fireproofing, intumescent material, and with non-inflammable silicone. The silicone is available in three colours (black, grey or white). The partition walls can thus have a height up to 3,6 m with modules’ width up to 1.5 m. Fire tests performed on these partition walls by the Poland’s Building Research Institute (ITB) included the so-called “free-edge model”, so there is no limit on the maximum length of this type of walls.

MB-78EI Muntin-free system brings you virtually unlimited design and construction possibilities of very large internal partition walling. Thanks to the transparent modules, all the constructions fabricated using this system make your interiors optically bigger. Our system also provides security by allowing the arrangement of the building’s fire zones, thus ensuring appropriate conditions for the evacuation of people

Advantages:

  • our solution has been designed and then tested at the ITB in two fire-rating classes: EI30 and EI60
  • joint width between the modules is only 4 mm
  • max wall height is 3,6m
  • max. width of a single module is 1.5 m
  • unlimited width of single walls,
  • constructions have been tested with hardened glass, that are much stronger and more resistant to impact than not-hardened glass

 

Window and door systems - General information

ALUPROF aluminium systems allow to fabricate many different types of windows and doors, depending on the scope and specific requirements for functionality, aesthetics, thermal insulation, burglary resistance, smoke control or fire resistance. These include both structures with no thermal insulation designed to fabricate internal partition walls and door (MB-45, MB-45 Office, MB-EXPO) or balcony developments (MB-23P system ), and solutions based on thermally insulated profiles (MB-60, MB-70, MB-59S). A significant part of thermally insulated systems is available in “HI” variant, and is characterized by special inserts into the profiles that lower the thermal conductivity coefficient.

The best thermally insulated structure offered by ALUPROF is the MB-104 PASSIVE system, which uses innovative materials and technical solutions. It’s one of the major ALUPROF product that perfectly meets the objectives of energy-efficient and passive buildings.

The MB series includes not only structures with the most common types of opening: side/bottom, but also lifting sliding patio doors MB-77HS, sliding windows & doors MB-Slide / MB-Slide ST, pivot windows“Pivot”, outward openable windows (e.g. MB-59S Casement) or windows dedicated to specific façade solutions, such as MB-60EF. We also offer “Industrial” type windows, dedicated to the revitalized historic buildings.
Numerous MB series systems allow for the fabrication of accordion doors, burglary resistant constructions, and smoke exhaust windows. For buyers who want to reconcile the right technical parameters with an affordable price, we offer a whole range of economic solutions, such as MB-45S, MB-59SE, and MB-60E.
Our window & door systems offering includes special, fire- and smoke-resisting partition walling: MB-78EI with the fire resistance class of EI15—EI90 and the MB-118EI with the fire resistance class of EI120. This group of products is completed by smoke-resisting doors with no fire resistance: MB-45D.
ALUPROF’s wide range of solutions is systematically developed in order to best meet the needs of contemporary architecture and meet the requirements of increasingly stringent standards and regulations.
