Alumil M85S

M85S is the new structural thermal insulated element curtain wall of Alumil (unitized - ready prefabricated units which can be erected without scaffolding) with inside face width of 85mm. It is the ideal option for large construction sites and tall buildings. It gives the ability to erect window wall prefabricated units especially for minimal design buildings. This advanced system has the following characteristics:

  • Only glazing with total thickness of 32mm or 44mm with double and/or triple IGU can be applied
  • The external glazing bars can be fitted easily and quickly, saving valuable construction time
  • Each “cell frame” can be applied in a pre-fabrication unit
  • A screw is placed at a specific point for a higher security level
  • Potential broken glasses can be easily replaced
  • Opening units fully integrated into load-bearing structure (top hung, fix, project out)
