Fire rated wall partitions of EI 120 - MB-118EI
Fire rated wall partitions of EI 120
The MB-118 EI fire rated walls are used to make fire partitions with fire resistance class of EI 120. The system is classified as non-fire spreading (NRO). It’s design & construction is such that, it provides a technical connection with the MB-78EI door, which means a number of common components (such as glazing beads, cooling inserts, expanding tapes, seals and most accessories) and also similar to the basic system, production and installation technology.
The MB-118EI system has been developed on the basis of a five chamber insulated aluminium profile, with a front to back depth of 118 mm. The inner chamber profiles, as well as insulating space between them, are filled with fire insulation elements. On the outer surfaces there are expanding tapes which are additionally mounted, and the whole structure is completed by steel accessories components, joining both sides of the profiles.
The MB-118EI system can accommodate glazing units, panels or other similar glazing substrates of a thickness 31-35 mm or 48- 84mm. Thanks to its symmetrical composition, the structures that are made of it remain fire resistant in EI 120 class, both exposed to fire from the outside and the inside.
An important feature affecting the functionality of the division of these partitions is the possibility to install the MB-78EI doors.
As regards the internal and external walls the MB-118EI system holds an ITB’s Technical Approval No. AT-15-9186/2013.
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.
