NVF2F is the  NVELOPE subframe system suitable for vertical floor to floor cladding applications

NVELOPE floor to floor (NVF2F) brackets and framework provide a framing system capable of larger spans than other bracket systems. Brackets are anchored to the building using primary fasteners, and each bracket allows for final alignment and adjustment to suit the external cladding. Suitable for supporting fiber cement, high-pressure laminate (HPL), aluminum composite material (ACM), and metal rainscreen panels.


  • NVF2F is a vertical back frame system for floor to floor spanning.
  • Floor to floor (mullion) box 'T' profiles are fixed using support brackets. Our brackets absorb wind loading and allow for expansion and contraction, and vertical dead loads.
  • Bracket spacing is determined by factors such as the dimensions and weight of the facade cladding, local wind loads, and cladding zone.

Material and standards

Manufactured from extruded aluminum alloys conforming to EN573-3 (material) and EN755 production standards.


NVELOPE brackets: allow 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 bracket and the primary structural support system) are available.  The isolators allow rainscreen installations to benefit from the low thermal conductivity values associated with reduced thermal bridging within the design.
