• NV3 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 with adjustable and fixed 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.


NV3 is suitable for mechanical secret fix cladding applications – fibre cement, high pressure laminate (HPL), ceramics or thin stone.
