Burglar resistance


All THERM+ curtain wall variants may be made burglar resistant in accordance with the German resistance categories RC2 and RC3 by adding a few supplementary system components. Providing maximum creative possibilities, all system widths and all types of pressure plates with clip on cover caps, visible screw fixings, as well as flat pressure profile plates (in RC2) may be used.


  • Extension of the standard systems by using additional shims with pressure-resistant backing and captivated ball bearing screw heads
  • For RC3 supplementary reinforcement to the pressure profile, captivated ball bearing screw heads, reduced screw spacing
  • No visual difference between the variations
  • Wide selection of pressure and cover profiles
  • System width and infill thickness as for standard systems
  • Manufacture is identical to the standard system, thus production and assembly is rationalised to the standard system
  • The production of glass roofs in class RC2 and RC3 is also available
