Aluprof S.A.




This system, based on the window structure of increased thermal insulation performance MB-70, is applied in building facades made of reinforced concrete or brick walls with window openings. In this kind of façade there are two types of areas: “cold” and “warm” ones. “Warm” area comprises thermally-insulated windows installed before the façade face in the window openings. Whereas “cold” areas are formed by the in-between window strips protecting the structure and thermal insulation (e.g. mineral wool) against weather conditions.

Application of this system significantly shortens the time of building due to the possibility of “closing” the window openings prior to creating the in-between window strips and the external façade coating.

The MB-70CW system features very good thermal insulation performance (the value of heat transfer coefficient Uf - depending on the applied profiles - ranges between 1,49 and 1,99 W/m2K. The system also meets the aesthetic requirements demanded by architects and investors, as regards such types of facades. Looking from the outside, the difference in appearance between the “warm” and the “cold” zones is not visible as well as between fixed and openable elements. Looking from the outside of the building, the strips of visible aluminium profiles are very narrow - their width equals 78.5 mm, which makes the structure look slender and light.
The MB-70 CW system is also available as an option with enhanced thermal insulation performance, i.e. MB-70CW HI, in case of which the value of heat transfer coefficient Uf – depending on the applied profiles and accessories – ranges from 1.43 tp 1.89 W/m2K. 

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.
