NVELOPE vertical cladding brackets come in standard dimensions of 40-300mm and in two sizes (single and double).
See 'project builder' - each bracket (60 - 300) has 40mm of adjustment. The 40 mm bracket has 20mm of adjustment.
A simple cladding support system typically consists of 'helping hand' brackets which are fixed to the substrate at set vertical and horizontal separations. There are vertical brackets (these will be used in the majority of cases) and horizontal brackets. Profiles are then fixed into brackets.
NVELOPE cladding brackets are made of aluminium EN AW-6063 T6 (former designation AlMgSi 0,5 F25) and comply with BS EN 755 as well as the common regulations for ventilated façades in Europe.

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.
