MB-SR50 HI Mullion-transom wall with enhanced thermal insulation

The curtain wall system with enhanced thermal insulation.

The energy saving of the whole building to a large extent depends on the thermal insulating power of its façade. In this respect, the MB-SR50 post and beam wall is able to face up to the higher and higher expectations of architects and investors of modern facilities.

The range of Aluprof systems includes the MB-SR50 HI system, in which the heat penetration rate of the sash section (U_f) ranges from 0.81 to 1.27 W/m²K. Such a high thermal insulating power of this construction was obtained by replacing the HPVC continuous thermal insulator by the PE one, which is characterized by low lambda thermal conductivity and very good insulation parameters, and by having raised the height of the sealing in relation to that of the standard façade version. The MB-SR50 HI façade allows the use of glazing of 26-44 mm. In addition to the high thermal insulating power, it has also got very good tightness parameters for water (RE 1200 class) and air (AE(1050) class) infiltration. The wind resistance is 2400 Pa.

The MB-SR50 HI construction was tested in the Lightweight Partitions and Glazing Laboratory of the Building Research Institute, which is confirmed by the Qualification Certificates no 351/2008/E and 351/2008/E.
