NV1 VERTICAL RAINSCREEN CLADDING SYSTEM

Developed as a back frame system, NV1 is suitable for face fixing of Luxyclad cladding.

NV1 is the basis of all NVELOPE cladding support systems.

 

FEATURES

  • NV1 is the NVELOPE back frame – vertical cladding applications.

  • NVELOPE 'T' and 'L' profiles are fixed using NVELOPE support brackets, fixed through a series of fixed and flexible points.

  • NVELOPE flexible point brackets absorb wind loading and allow for expansion and contraction.

  • 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 and cladding zone.

 

INSTALLATION

  • Vertical profiles attach to brackets by a combination of fixed and flexible points to allow for dead and dynamic loads. Flexible points are vital due to the differing thermal performances of the materials being combined.                                                                     

  • Dead and dynamic loads plus expansion and contraction must be taken into account. The façade has to be able to float on the sub-construction. Every element of the façade construction must have only one fixed point. All other fixing points must be executed as floating or moving points.                         

  • Fixed point brackets and profiles are connected by round holes in the bracket. The fixed point absorbs both vertical weight loads and horizontal wind loads.

  • Flexible point bracket and profiles are connected at the elongated holes in the brackets. Their primary function is to absorb dynamic horizontal wind loads.

  • The length of profiles in vertical cladding systems depends on the storey height.                                                                    

  • Due to possible expansion, the relationship between the façade material and the cladding support system must be considered.                                                     

  • Using a preliminary survey of the wall and architectural structural design, a grid layout for the sub-frame is prepared. Brackets (with insulating pad) are fixed to the substrate wall using stainless steel fixings of appropriate size for the design. The pull-out value of the securing fixings should be determined on site from the pull-out strength and appropriate safety factor as given in BS 5427-1: 1996.                                                                                      

  • The rails are friction held into the brackets by the 'helping hand' and after adjustment for line and level, are fixed using self-drilling stainless steel screws.
