KBE 70 mm windows are compatible with all types of hardware. Hardware fasteners with window installation screws in min two profile walls or in special coextruded screw channels; also in the steel reinforcement for extreme sash weights.
Special design for the interior walls of the profiles for the sashes in KBE 70 system for an additional strength whatever the steel reinforcement inside the profiles.
KBE 70 windows profiles are available in a wide range of colors: from the simple, plain colors to different wooden foils.
Increased noise insulation with an accoustic value Rw up to 45 Db using glass panes and sandwich panels (24 mm - 52 mm thick).
Coextruded weather resistant gaskets, light grey and black, can be easily replaced. They assure a higher tightness and optimal protection without having problems with the condensation.
Thermal insulation coefficient – U value
Uf = 1,3 W/m2K
Uw up to 0,84 W/m2K (according to the specific configuration, dimensions and glazing)
Glazing possibilities: 24-52 mm
Sound insulation value up to Rw (C,Ctr) = 30 (-1;-4) db
