NV4 System


  • NV4 (ts200) is the NVELOPE® system for secret fix/ mechanically fixed applications.
  • Secured using hangers and undercut stud anchors or screws to provide a concealed fixing.
  • Horizontal NVELOPE® channel profiles are fixed to the vertical profiles. Rainscreen panels are hung from and secured to the horizontal profiles and the adjustable and static hangers.
  • NVELOPE® ‘T’ and ‘L’ profiles are fixed using NVELOPE helping hand support brackets, fixed through a series of fixed and flexible points.
  • NVELOPE® flexible point brackets absorb wind loading and allow for expansion and contraction.
  • NVELOPE® fixed-point brackets absorb both vertical dead loads.
  • NVELOPE® Bracket spacing is determined by cladding options such as the dimensions and weight of the facade cladding, local wind loads.


NV4 (ts200) is suitable for mechanical secret fix cladding applications (Trespa Meteon HPL).
