NV8 is the NVELOPE® subframe system suitable for concealed fix/mechanically secret fixed and structurally bonded applications
NV8 is an alternative NVELOPE system for secret fix/mechanically secret fixed applications. NV8 is an alternative solution for structurally bonded applications – On site or offsite secured using hangers and TUF rivets, screws or structural adhesive (Sika) to provide a concealed fixing.
Horizontal NVELOPE profiles are fixed to the vertical profiles. Rainscreen panels are supported by and secured to the horizontal profiles with hangers and adjustable hangers.
NVELOPE 'L' profiles are fixed using NVELOPE support brackets, fixed through a series of fixed and flexible points. NVELOPE fixed point brackets absorb 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. NVELOPE sliding point brackets absorb wind loading and allow for expansion and contraction.
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 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 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 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.
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.
