NVELOPE THERMALLY BROKEN CLADDING SUPPORT SYSTEM
INSTALLER FRIENDLY, TRIED & TESTED
NVELOPE RAINSCREEN CLADDING SUPPORT SYSTEM IS ENGINEERED WITH ADJUSTABLE BRACKETS AND RAILS AVAILABLE IN VERTICAL OR HORIZONTAL INSTALLATIONS AND ARE COST EFFECTIVE, EASY TO INSTALL OR ADJUST AND ACCOMMODATE A WIDE RANGE OF CAVITY DEPTHS. THE NVELOPE SUPPORT SYSTEMS MEET STRUCTURAL AND THERMAL DEMANDS OF TODAY’S BUILDING REQUIREMENTS.
Manufactured from extruded aluminium alloys conforming to EN 573-3 (material) and EN 755 production standards.

NVELOPE brackets (V): allows adjustment between the face of the primary support to outer face of vertical profile.
Thermal isolators: hard PVC isolator assembled as standard (located between the NVELOPE bracket and the primary structural support system).
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.
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.
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.
