We are delighted to announce that we will be introducing our MB-79N door system on 20th April 2021. The MB-79N, an innovative window and door system, is a state-of-the-art addition to the ALUPROF range and our response to the regulations of the WT (Technical Conditions) 2021.

We are expanding our range to include doors designed on the basis of our MB-79N system in order to offer a solution with enhanced thermal and acoustic insulation. The successor to our highly popular MB-70 solution, which is widely used in the construction industry, the MB-79N’s profiles are just 70 millimetres wide. They are designed to allow the surface of the leaf and frame to be flush on both the interior and exterior. The shape of the profiles means that a slender, durable structure can be built without sacrificing the excellent kinematics. A wide selection of profile sections guarantees that the aesthetics and durability required for the structure can be achieved. In addition, the MB-79N makes it possible to produce panel doors, further extending the potential for personalised finishing. MB-79N doors can measure up to 2.8 metres tall and 1.4 metres wide and they can weigh as much as 200 kilos. Even in the case of such a large structure, using the door remains straightforward and trouble-free, since cutting-edge hardware can be used in conjunction with automation and access control with doors produced on the basis of our systems. The ALUPROF MB-79N is available in three variants, which differ in terms of the level of insulation. The MB-79N E is the most economic solution, with a simple, central gasket. The MB-79N ST is fitted with a two-component gasket and the MB-79N SI, which provides the best thermal insulation, features profiles fitted with expanded polystyrene (EPS) insulating inserts and a two-component, central gasket. The thermal breaks in the system are produced using an innovative material with a new shape, making it possible to use an additional gasket in the isolation zone of the SI and SI+ variants, in other words, insulation inserts in the thermal break zone. The value of the U heat-transfer coefficient f ranges from 2.16 W/(m2K) for the ST, from 1.76 W/(m2K) for the SI and from 1.22 W/(m2K) for the SI+.

Advantages and functions of the ALUPROF MB-79N

Thermal parameters

- The best thermal isolation on the market for the profile depth - The thermal insulation makes it possible to meet the requirements of the WT 2021 (Uw < 0.9 W/(m2K)) for a reference window - Thermal inserts produced using state-of-the-art technology. They play an important part in attaining the high heat insulation parameters and are produced using innovative materials with a low thermal conductivity of λ (lambda)

Performance parameters

- The best watertightness parameters on the market; E4500 watertightness for a reference window - Acoustic insulation of 46 dB for glazing with a value of 47 dB; the profile structure and sealing system is optimised by using two-component gaskets

Optimal construction

- The only solution on the Polish market to feature aluPilot hardware, making it possible to reduce the prefabrication time per window by around ten minutes - The kinematics mean that sashes with a width starting from 250 mm can be produced - A maximum sash width of 1350 mm and a maximum height of 2700 mm Sashes dedicated to 9 and 13 millimetres circumferential PVC fittings and ALU fittings - A solution adapted to the regulations applicable on most foreign markets - A wide range of window and door solutions, including solutions for export markets - Numerous types of glazing bars of various heights - A wide selection of glazing up to 63 mm, meaning that double glazing with parameters of Ug = 0.5 W/(m2K) can be used - Hardware in the same colour as the joinery or a choice from a number of handle series that match it
