NVELOPE® Thermal Solutions
Utilising its UK Patent Pending technology SFS have been able to create a high performing solution that guards against thermal degradation due to compression of the thermal pad, ensuring no loss in thermal performance. This combined with the bracket material of Aluminium or stainless-steel ensures that a full range of tailored solutions can be created for any project.
Thermal performance and heat loss
The NVELOPE® rainscreen support brackets, primary fixings, rails and carriers are an integral part of the Rainscreen Cladding build up and their impact on heat loss in the construction plays a key role. As dwellings have become better insulated, the importance of thermal bridging has increased. In very well insulated dwellings, the effect that thermal bridging can have on the overall thermal performance of a dwelling can be significant. All NVELOPE® aluminium and stainless-steel brackets are de-fined as Euroclass A1 Non-Combustible EC Directive – 94/611/EC. The Thermal pad has an A2 Non-Combustible Euro classification.

SFS NVELOPE® Systems
The NVELOPE® range is made up of brackets and rails in various configurations to suit your application. All systems are available in aluminium, and all systems can be supplied with the insulation pad for enhanced thermal performance. Most systems are also available with stainless steel brackets to improve thermal capabilities even further

NVELOPE® VB/HB aluminium brackets are supplied with a green plastic ‘isolator’ which offers a degree of thermal benefit. However, its principal function is to eliminate any potential of galvanic corrosion between masonry and aluminium substrates.
NVELOPE® VB/HB + Thermal
Whilst strong and easy to install aluminium is very thermally conductive e.g. > 200 W/mk. The NVELOPE® VB/HB + Thermal range includes an insulation pad at the base of the bracket. This dramatically improves the thermal performance of the rainscreen of the rainscreen build-up.
NVELOPE®’s stainless steel range is made from superior 316 grade which exhibits far greater resistance to localised corrosion in marine and in contact with atmospheric pollution found in most built up environments. Typically, stainless steel is approximately 16 W/m/K. This represents a 12-x thermal improvement over and above aluminium. Additionally, stainless steel brackets have no requirement to utilise an isolator to alleviate galvanic corrosion.
NVELOPE® NVS + Thermal
For optimum thermal performance NVELOPE® NVS + Thermal is the ideal choice. It offers the combined benefits of high thermal performance with high corrosion resistance for costal environments. Where rainscreen build up designs prescribe demanding thermal solutions, the option could offer the ideal high-performance answer!
