the requirements for each façade and cladding system are always different and depend on factors such as local wind loads, height of the façade, substrate being fixed to, selected cladding material and the cladding zone. all NVELOPE cladding systems can be engineered to project specific requirements.
unlock your scheme by completing and submitting the NVELOPE project checklist (ideally accompanied with elevation and plan autoCAD drawings, indicating your proposed cladding requirements).
this will allow us to prepare a project specific cladding solution that includes static calculations and setting out information for the support system, thermal calculations and indicitive m2 price.
please don’t hesitate to contact our technical department for specific advice.
a static calculation assesses dynamic forces e.g. wind load and dead loads (weight of the cladding) under project circumstances. in engineering, static systems do not move or change state – therefore a static calculation is ensures that under a given set of circumstances the system (mix of brackets and components) will not move and it will support the load that it’s intended to support.
the 2010 revision to Part 'L' places specific emphasis on the performance of the building details and the additional losses through linear thermal bridging. the thermal value of NVELOPE brackets has been calculated.
thermal bridges cause increased flow of heat and should be taken into consideration when designing a façade or façade system. since the anchoring for ventilated cladding must go through the thermal insulation into the substrate thermal bridging cannot be avoided.
NVELOPE NV and NH brackets are pre-assembled with thermal isolators – isolators help reduce thermal bridging.
the additional heat loss for each m2 of a detail is known as the PSI (?) value and this additional heat loss is dependent upon the type of detail, the thermal conductivity of the cladding materials and the quality of the detail design and installation.
setting out information which is produced by the project checklist allows for guide m2 price rates to be determined.
Nvelope Rainscreen Cladding bracket support systems and associated fixings have been designed in accordance with the new Eurocode 9 (EC9) and are implemented to National Annex BS EN1999.
Some of the aims and benefits of the Eurocode are to:
Provide common design criteria and methods
Provide a common understanding of construction products
Facilitate the exchange of construction services
Be a common basis for research and development
Allow the preparation of common design aids and software
Increase the competitiveness of European civil engineering firms, contractors, designers and product manufacturers in their world-wide activities
The EC9 provides common structural design rules, so meeting the compliance requirements of the EU. Plus Eurocodes have been recognised as the leading structural codes. Their flexibility enables use internationally, as evidenced by their adoption by several countries outside Europe.
The Eurocode 9 (BS EN 1999-1-1 : 2007+A1 : 2009) applies to the design of structural works in aluminium and complies with the principles and requirements for the resistance, durability, serviceability and safety of aluminium structures.
