Our façade systems are used to fabricate glass façades of buildings such as banks, hotels, administration offices, office buildings, car showrooms, gyms, etc. They are also used for multiple spatial structures and roof glazing that light the interior and create a suitable atmosphere and comfort to its users. They are an excellent tool for shaping contemporary architecture and implementing designers’ bold visions. The most popular among these products are the mullion-transom systems. BERTRAND”s façade solutions include also a range of products of various design and appearance, including a bunch of individual solutions.
SEMISTRUCTURAL MULLION/TRANSOM CURTAIN WALL
The MB-SR50N EFEKT system is used for the construction of lightweight curtain walls of a hanging and filling type as well as roofs, skylights and other spatial constructions.
Its supporting structure is based on a modern and tried-and-tested mullion and transom aluminum system MB-SR50N, which provides a wide range of profiles to choose from and the possibility of selecting sections so that the surface of mullions and transoms is flush with the internal side of façade, and thus its aesthetic joint with development elements inside the building is ensured. It also ensures compatibility with other constructions based on the wide range of products offered by BERTRAND.

The shape of the mullions and transoms allows you to build aesthetic facades with visible narrow dividing lines, while ensuring the durability and strength of the structure.The rounded shapes with a radius of 2.5 mm, characteristic of the MB-SR50 system, have been replaced with the so-calledsharp edge.This procedure significantly affects the aesthetics of the structure – the profile shapes used enable the selection of mullion and transom profiles, which gives the effect of flush surfaces of mullions and transoms from the inside of the façade.Thanks to this, the glazing can be constructed as a uniform grid.This also facilitates aesthetic and precise connections with other building elements: internal walls and suspended ceilings.Characteristic features of the MB-SR50N system include a large range of column profiles (from 65 mm to 325 mm) and transoms (from 5 mm to 189.5 mm) as well as modern solutions for accessories and connectors.They allow for increased ranges of transferred loads – the filling of the permanent facade module can weigh up to 450 kg.The MB-SR50N system gives considerable freedom in designing façade mounting points; a wide range of glazing also allows the use of large-size glass and double-chamber insulating glass.
Among the solutions we offer, mullion-and-transom facades in the MB-TT50 system are extremely popular.Why?Because it uses an innovative approach both in terms of the construction of profiles and accessories responsible for tightness, as well as assembly technology.Therefore, aluminum facades in the MB-TT50 system are characterized by some of the best parameters on the market, meeting even the highest requirements set by passive construction.Remember that, depending on individual needs, we offer not only MB-TT50 series facades, but also MB-SR50N and MB-SR50.
