Alumil Μ50

M50 is a complete system for High Energy Efficiency curtain walls that offers unlimited design freedom and meets all requirements of contemporary architecture thanks to the following characteristics:

  • 50 mm width of mullions and transoms
  • High thermal insulation up to Uf=1,0 W/m2K, making the system ideal for all climate regions and for low energy buildings
  • Big variety of mullions for high wind loads with the possibility of standard shape steel reinforcements
  • A variety of designs for the visible aluminium covers offer outstanding design options for a variety of façade styles
  • Structural glass version without aluminium covers, with the same mullions and transoms
  • All kind of opening windows in the curtain wall (parallel projected, top hung, inwards tilt & turn, concealed sash tilt & turn, seamless inwards tilt & turn)
  • Burglar resistance: RC 3 (WK3) anti-burglar protection
  • Bullet resistance (FB6) and fire resistance (EI 30) options
  • Exceptional sound insulation with the addition of P50
  • All kinds of surfaces can be constructed (inclined, polygonal)

Μ50 Structural
The main difference between M50 Structural and M50 Standard with visible covers is the appearance of the exterior surface. 
M50 Structural is characterized by the absence of aluminium profiles on the façade, which creates a continuous glazing surface even for top hung & parallel projected windows.

Μ50 Energy Fire Proof Series 30
M50 Fire Proof Series curtain wall covers every niche market concerning fire protection. 
Certified for 30 minutes fire proof, when M50 Fire Proof Series is combined with appropriate fire proof glazing, it provides crucial time for building evacuation in case of emergency.

Μ50 security
M50 provides security curtain wall solutions and is applied on constructions that require high protection such as banks, embassies, government agencies, jewelers, etc. The variety of glazing can significantly increase the security level of the system depending on the requirements.
