Our projects

What is so special about MB-79N windows and doors?

The key feature of the MB-79N system is its high thermal insulation. Thanks to the top-quality aluminium and innovative technologies, such as the special thermal breaks, double or triple glazing units or two-component central seals, our products achieve an excellent insulation performance (Uw from 0.64 W/(m2K)). They not only guarantee a significant reduction in heating costs but also improve the comfort of living for the residents.

Every detail of MB-79N windows and doors has been designed for long-lasting functionality and aesthetic appearance. We offer a wide range of finishes, glazing and hardware types, including the option of providing the doors with access control and automation systems. This approach enables full customisation and adaptation to the individual needs and style of the house to emphasise its unique character.

MB-79N doors and windows – security and functionality on the highest level

Security is our priority, which is why our products meet the most stringent requirements for burglary protection, with resistance classes from RC1 to RC3. This means that when you invest in MB-79N energy-efficient windows and doors, you provide your home with an effective barrier against undesirable guests while still enjoying high energy efficiency and aesthetic appearance.

Our windows and doors have also been tested in extreme weather conditions to confirm their exceptional resistance and durability. That is why the MB-79N system is not only an investment in comfort and security but also in the value and prestige of your home. Give yourself peace of mind with solutions that have become synonymous with modern technology, functionality and excellent design.

The MB-79N is a state-of-the art and economical addition to the Aluprof window & door systems. It has been designed to outperform typical thermal insulation requirements. The MB-79N series can be used to fabricate fixed, side-hung, hopper, tilt-and-turn, and hopper-and-slide windows, as well as single and double exterior doors, and storefront solutions complete with doors. In addition to the economical version MB-79N E, featuring a one-component central seal, and the MB-79N ST version with a two-component central seal, Aluprof also offers the MB-79N SI variant with enhanced thermal insulation, and with profiles that come equipped with insulating inserts and a two-component central seal. For external doors, Aluprof also offers the MB-79N SI+ variant that comes with a central seal and insulating inserts inside the profiles.


  • profile depth: 79mm (casement) and 70mm (window frame and door leaf)
  • thermal breaks made of an innovative material with a brand-new shape allow the use of a seal in the area of profile insulation, in both windows and doors
  • Windows in 3 thermal variants (MB-79N E, MB-79N ST, MB-79N SI) and doors in 4 thermal variants (MB-79N E, MB-79N ST, MB-79N SI and MB-79N SI+)
  • thermal insulation: Uw starting from 0,64 W/(m2K), Uf starting from 0,83 W/(m2K)
  • excellent kinematics enabling the fabrication of narrow, operable windows and doors
  • door leaf profiles have isolation joint, which eliminates thermal stresses during operation
  • possibility of using invisible hinges and the most popular multi-point hardware, including hidden fittings + state-of-the art AluPilot fittings; for doors, fittings with automation and access control functions are also available
  • able to receive double or triple glazing, up to 63 mm for windows and 54 mm for doors, thus making it possible to use all common types of glass, including acoustic or burglar-resistant glass
  • possibility to produce security doors rated RC1 - RC3, and panel doors in many highly aesthetic versions
  • large selection & different styles of handles, including minimalist looking handles with or without rosette
  • Aluprof obtained positive results of hurricane tests conducted for the MB-79N system in accordance with ASTM guidelines and Florida Building Code TAS 201-94, TAS 202-94 and TAS 203-94
