NVF2F is the NVELOPE® back frame system for vertical floor to floor cladding applications

Suitable as a back frame system – NVF2F is suitable for face fixing / rivet fixing cladding – elements to e.g. fibre cement, high-pressure laminate (HPL) and metal rainscreen panels. NVF2F can support NV3 / 4 / 5 and 8.


  • NVF2F is the NVELOPE back frame – vertical floor to floor cladding applications.
  • NVELOPE floor to floor (mullion) box 'T' profiles are fixed using NVELOPE support brackets NVELOPE brackets absorb wind loading and allow for expansion and contraction and both vertical dead loads.
  • NVELOPE Bracket spacing is determined by cladding options such as the dimensions and weight of the façade cladding, local wind loads and cladding zone.


Manufactured from extruded aluminium alloys conforming to EN 573-3 (material) and EN 755 production standards.


NVELOPE brackets (V): allows adjustment between the face of the primary support to outer face of vertical profile. Thermal isolators: hard PVC isolator assembled as standard (located between the NVELOPE bracket and the primary structural support system).
