Aesthetic value and high performance

Aesthetic value and high performance through the use of the most modern profiles made of STAINLESS STEEL or ALUMINIUM. VELLETRANI is capable of producing a wide variety of glass facades, with high aesthetic value and highly effective structural capacity.

Thanks to small architectural sections (45 or 60 mm), large transparent facades can be made of steel and stainless steel (CE classification according to EN 13830), and by freely matching profiles, high customization of the construction can be achieved, such as approved oblique glazing with roof slopes from 10 to 75 degrees.

In addition, rational and therefore economical facade design is possible due to a number of objective factors, such as: the reduced number of system components, a high thermal insulation coefficient, which allows significant energy savings for the building, and unlimited durability that excludes extraordinary maintenance activities.

THE ADVANTAGES OF CURTAIN WALLS

The technology of Vertical Facades, made of Steel and Aluminum, guarantees a number of construction parameters, such as:

Vertical Facades

  • Thermal insulation: Uf coefficient 1.1 – 2.2 W/(m2.K) (depending on fill thickness) when using a housing insulator
  • Classification by CE testing according to EN 13830
  • Air permeability according to EN 12153: AE 750
  • Tightness to driving rain according to EN 12155: R7 (600 Pa)
  • Wind load resistance according to EN 12179: 3000 Pa
