MB - 23P is the aluminium system destined for balcony glass enclosures. The concept of this solution involves the horizontally sliding windows. Windows basing on this system protect the balcony open space against the unfavourable atmospheric conditions such as: wind, rain, snow as well as dirt and noise. At the same time, the MB-23P system structures hinder burglary, which is particularly essential while living on the ground floor.

The structural depth of sections is equal to 53 mm (frame) and 23 mm (casement). Owing to external housing, the structure built basing on the MB-23P system has the effective water drainage and ventilation systems from the window glass chambers and from the chamber between casement and a frame. The window casements can be filled with a single pane of the thickness equal from 4 to 8 mm, or with safe glass of the thickness equal to 6.4 mm. Thickness of the glass is selected depending on the height at which the balcony is situated, its location and the casement overall dimensions.

The MB-23P system can be used both in already existing balconies as well as in adjoined ones. It can be applied not only in balconies of simple design: thanks to application of the MB-45 window/door profile system, it is possible to create angular connections between the individual windows that are adjustable in a wide range. The enclosure built with this system is characterised by a very easy and fast prefabrication, thanks to elimination of the majority of time-consuming mechanical working processes, what favourably influences the final price of the product.

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.
