The energy saving of the whole building to a large extent depends on the thermal insulating power of its facade. 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 new version, MB-SR50 HI, in which the heat penetration rate of the sash section (Uf) ranges from 0.85 to 1.23 W/m2K depending on the filling thickness, is now being launched.
Such a high thermal insulating power of this construction was obtained by replacing the HPVC continuous thermal insulator by the PE one, which is characterised 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 facade version. The MB-SR50 HI facade 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, issued in February 2008.
