About

  • NVELOPE® NH3 is the system used to support vertical elements, allowing for varied façade design options.
  • The system has a number of advantages over the NH2 system, making it faster and easier to install. It is also supported by the SFS range of fasteners.
  • Specifically designed to speed up and simplify the installation process.

Applications

The bracket is secured to the substrate; either steel frame, block work, or timber. The horizontal slot of the bracket is then ready to receive an L or T rail.

The L and T rail can be adjusted for line and level and secured using fixed and sliding positions to allow for expansion and contraction.

This system is suitable for face fixed applications. Elements to which it can be fixed include:

The system has a number of advantages over the NH2 system, making it faster and easier to install. 

  • Fibre cement Panels
  • Glass reinforced concrete (GRC)
  • High pressure laminate (HPL)
  • ACM & Solid Aluminium Cladding
  • Metal rainscreen panels

Material

The selection of materials to use in the construction of a subframe system within a rainscreen façade is of paramount importance. Material choice can also affect the thermal performance of the overall rainscreen in addition to engineering assurance.

  • Aluminium is inherently corrosion resistant however this can be complemented and further improved by additional treatment including anodising and powder coating.
  • All NVELOPE systems only use the superior 6005 T5 alloy, which provides superior strength and performance over and above other commonly used aluminium.
