Bertrand Windows and Doors

Style and warmth with MB 79 SI

The best thermal insulation combined with modern design that meets the needs of each project. That's the system MB 79N SI, an aluminum system in which various structures can be made window and door.

– MB 79N is our most popular aluminum window and door system due to its universality - says Olaf Bertrand, director of marketing and export at Bertrand. – This system is very well priced in relation to the market and is characterized by an excellent quality-to-price ratio, it looks very attractive because the sash is flush with the window frame, which makes it look very delicate and windows opened from the outside look almost like fixed windows. The frames of this system are lower than in the case of PVC and wooden systems, so more light enters the rooms. Additionally, it is worth noting that the maximum height of the window sash in this system is as much as 2.7 m, so the absolute majority of architecturally advanced projects can be equipped with this solution.

In order to meet the increased thermal insulation requirements (Uw from 0.64 W/(m2K)), this solution uses profiles equipped with insulating inserts and two-component central seal. Other advantages of this solution include: high degree of security due to the possibility of making anti-burglary doors (also panel doors) in classes from RC1 down RC3, excellent waterproofness (E 1950) and kinematics allowing the construction of narrow opening windows and doors, and the possibility of using hidden fittings without visible hinges.

It is also worth noting that MB 79N SI provides a wide range of glazing packages 2- or 3-glazed (thickness up to 63 mm for windows and 54 mm for doors), which makes it possible to use all possible types of glass, also acoustic Whether anti-burglary. The depth of this solution is 79 mm and 70 mm respectively for the window sash and the door frame and door leaf.

– This system is perfect for both residential and commercial construction. For more demanding users, MB 79N also has a solution with a completely hidden sash in the frame from the outside - underlines Olaf Bertrand– Such solutions have recently been very popular with our clients. I will also add that Bertrand can offer solutions with a hidden leaf also in PVC and wood-aluminum in the Kubus and Synergic systems, which I also heartily recommend.

Products in the system MB 79N SI can be configured in any color, according to the customer's taste. A wide range of colors is available, some of which are presented below. It is also worth mentioning that this solution has been certified by NFRC (National Fenestration Rating Council) and AAMA (American Architectural Manufacturers Association).
