About
- NV2 is the NVELOPE subframe system for vertical cladding applications.
- NVELOPE 'T' and 'L' profiles are fixed using NVELOPE support brackets, fixed through a series of fixed and sliding points.
- NVELOPE sliding point brackets absorb wind loading and allow for expansion and contraction.
- NVELOPE fixed point brackets absorb the 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.
Applications
Adjustable, thermally broken, sub-framing system – NV2 is used for concealed chemical bond fixing of cladding panels. For example,
- Ceramic panels
- Stone
- Fibre cement Panels
- Glass reinforced concrete (GRC)
- High pressure laminate (HPL)
- ACM & Solid Aluminium Cladding
- Metal rainscreen panels
Features
- Manufactured from extruded aluminium alloys conforming to AS/NZS 1866:1997 (material) and EN 755 production standards.
- Non-Combustible to AS1530.1**
- Suitable in high corrosive environments C4 and C5.
- Thermally broken to meet Section J NCC 2019 & 2022 thermal bridging requirements.
- Engineered to Australian Standards.
**Nvelope framing and fasteners only. The connection to the cladding utilises a chemical bonding process. The adhesives used are considered combustible, therefore a performance solution will be required for type A or B construction projects. Seek advise from a certified fire engineer if you are to use NV2 in these classification types.

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.
