NV6 Rainscreen Subframe System

Features

• NV6 is the NVELOPE subframe system suitable for supporting a timber batten (to support vertical and/or horizontal cladding elements).
• Timber batten can be used to support timber cladding/weatherboarding and ply.
• NVELOPE fixed and sliding points located on the NV6 adapters allow for expansion and contraction.
• NVELOPE bracket spacing is determined by cladding options such as the dimensions and weight of the facade cladding, local wind loads.

Supports

• Vertical timber cladding: vertical timber battens are supported with NVELOPE carriers brackets fixed back to NVELOPE support brackets.
• Horizontal timber cladding: vertical timber bearers are supported with NVELOPE carriers fixed back to NVELOPE support brackets, then counter battened.

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

• Aluminium subframe systems for rainscreen are designed in accordance with BS EN 1090-3:2008 and / or Euro code 9 – Parts 1-4
• Aluminum is the second most widely used metal after iron and as such has a robust and well defined UK and international supply chain
• Its low weight and high strength ratio and  simplicity of fabrication either on site or within a manufacturing setting ensures it is an ideal material with which to create high performance rainscreen subframe systems for cladding applications.
• Aluminium is inherently corrosion resistant however this can be complemented and further improved by additional treatment including anodization whilst still maintaining a Euroclass A1 fire rating.
• NVELOPE systems only use the superior 6005 T6 alloy which provides superior strength and performance over and above other commonly used aluminum.

Stainless Steel

• Stainless steel  subframe bracket systems for rainscreen are designed in accordance with BS EN 1090-3:2008 and / or Euro code 3 – Table 5.1
• NVELOPE stainless steel brackets are only manufactured from a superior 316 grade of alloy to provide an outstanding level of resistance to localised corrosion such as maritime and polluted areas.

Sustainability

Sustainability is a key factor in the design of any building. Identifying the right material from a sustainable manufacturer with a credible supply chain and responsible sourcing is crucial. At SFS:

• The aluminium we manufacture from is 100% recyclable
• The alloy we use is made from 100% re-melted material
• 6063 alloy  as used by many other sub frame manufacturers’ can only utilise 40% recycled scap due to global shortages.
• CO2 production as a consequence of extrusion alone estimated at 0.35 – 0.5Kg per Kg currently.

Options

• Utilising our proven technology of Project Builder Thermal you can enable any project to be optimised for performance and budget. Whether a lower or a higher thermal performance is required our Thermal Solutions range offers the ability to fine tune your project requirements.
• NVELOPE brackets allow for adjustment between the face of the primary support to outer face of vertical profiles.
• Green isolators (hard polypropylene isolator) assembled as standard, allowing rainscreen installations to benefit from the low thermal conductivity values associated with reduced thermal bridging within the design.
