As a response to the growing demand for building products with high thermal insulation, windows and doors with thermal break systems have been developed MB-70HI, MB-70US HI and windows built into the curtain wall system MB-70CW HI . Their design is based on a system known for its srength and durability, the MB-70, MB-70US and MB-70CW.
Thermal insulation of the system is much larger than the thermal insulation of the base system, so that constructions using MB-70HI system, Uf factor is 1.0 – 2.3 W / m²K, depending on the profiles and accessory used.
Increased thermal insulation is achieved through special isolation room placed in the middle, joining the aluminum profiles. Profile of insulation is characterized by low values of thermal conductivity and reduce heat flow. The central location also limits the contributions of convection and thermal radiation.
The windows and doors system MB-70HI, as in the case of the basic system can be used both in individual solutions, as well as the facades of aluminum, where the junction between the upright and the straight edge part of the system, MB-SR50 HI isolation improved heat.
MB-70 is a modern aluminum system that is used for the the execution of architectural elements that require thermal and acoustic insulation, such as various types of windows, doors, windows, structural construction etc.
The system profiles are divided into three rooms, building a profile depth is 70 mm for windows and 79 mm for the sash frame and doors 70 mm and 70 mm. If tread depth of sash and frame give the effect of one surface from the outside after closing – in the case of the window, and the effect of a doubling of the sash and frame surface – if the door. The shape of the profiles enables the construction of doors and windows and esthetics. The MB-70 system is also possible of windows with so-called “hidden casement” MB-70 and MB-70 Industrial US, which is great postindustrial modernization of buildings, history and monuments.
The MB-70 is characterized by a low coefficient of heat transfer U – due to the use of special heating and gaskets. This is very important when the requirements of energy saving and environmental protection are becoming increasingly demanding. The system profiles meet the thermal requirements of material group 1 for Windows and 2.1 for doors, according to DIN 4108. thermal bridges used in this system is shaped like the letter “omega” width of 34 mm to 24 mm for windows and doors, made of polyamide reinforced with glass fibers. The specific shape of the polyamide increases the rigidity of profiles compared with polyamides and facilitates drainage of flat sections, while ensuring an adequate thermal insulation in any weather conditions. Thermal compartments used in windows are additionally sealed.
Due to inter alia the use of such forms of thermal compartments for increasing the thermal insulation is not necessary to complete the surface of this foam.
Sealing is ensured through the use of special seals of two-component EPDM synthetic rubber: solid and cellular, which guarantees aging resistance during long operation and a very good thermal insulation. MB-70 is the first system that has been used to achieve the center seal material.
The system allows the use of glass packages with between 21 and 57 mm thickness for windows and between 12 and 48 mm for fixed panels or doors. A wide range of both filling guarantees the possibility to use all types of standard or non-standard windows.
Wide assortment of colors in the standard can satisfy the most demanding customers.
The MB-70 possesses the technical approval of the construction techniques of the Institute (ITB) for windows and balcony doors (AT-15-4647 / 2000)
Lif and slide doors are an ideal solution for connections between rooms or greenhouses with the outside environment, providing a convenient exit to the balcony, terrace or garden. Allows good contact with the environment and in open space not retain chamber, which raises the comfort of their use. The MB-77HS is one of the products with the best parameters and meets all requirements for this product group. They can be constructed in two different insulation options: ST and HI. Construction door profiles allows exclusive bulky glass with one or two rooms, and the materials and technical solutions used helps achieve a high degree of thermal and sound insulation. Due to its characteristics, this system is ideal for both houses as well as comfortable apartments or hotels.
Due to a rich offer of profiles , architects and designers can realize the most avant-garde ideas in the construction of aluminum and glass.
The system is intended for building and implementing protective walls easily, and roofs, skylights and other structures.
Form pillars and struts permit to construct aesthetic facades with slender lines of separation visible, while ensuring strength and durability of construction. In addition, the profiles have rounded outer corners, allowing the creation of the effect of the so-called “soft-line”.
The large number of mullions and rods available in the system guarantees optimal aluminum consumption. Due sectional shape optimization and choosing the appropriate thickness of the wall were obtained economic profiles. In the case of high stresses on all the posts may be established on the inside with aluminum typical, leading to increasing their resistance. Easy processing of profiles reduces preparation time, eliminating any cuts in the side surfaces of the uprights.
The use of thermal barrier material made of HPCV continue and the trim of the EPDM allows achieving a RMG 2.1 insulation class according to DIN 4108.
To bottle the coefficients of the frame is RD = 2.21 [W / (m2 * K] which allows to obtain a temperature of -10 ° C to the outer surface of the column and minimizes the phenomenon of condensation of water vapor on the elements aluminum.
Due to the layered construction of parapet areas under the windows, where no flammable materials were used but mineral wool or gypsum boards, the product received fire protection rating according to building F0,25 (EI15) NRO and F0,5 (EI45) NRO.
In order to achieve the curved angular curtain wall in the vertical and / or horizontal profiles have been provided for special sealing and masking, which leads to lack of forming the limits of the building body and eliminates the need for use of special angular pillars. The accessories shipped with the system, brackets and aluminum joint that secures the wall construction of the building are made of aluminum alloy AlMgSi0,5F22.
If MB-SR50 based facades can use masking profiles of different shapes. A very aesthetic façade variation is the so-called vertical and horizontal lines, which emphasizes sharing – vertical or horizontal. This system is also the basis for other solutions: wall “semi-structural” MB-SR50 EFEKT, the façade of “Industrial” building used for application to a skeleton of a wood or steel (MB-SR50 A) and facades where the glass plates are used for post stiffener construction. For these types, besides the elements that open the standard mode can be used or the folding roof windows which are based on structural wall system MB-SR50.
