NVELOPE
Hangers & Panels.
NVELOPE | Method Statement — Installation Guide NV7.
Once all brackets and
proles are installed to an
area of cladding, nal checks
should be carried out:
On the primary anchor
torque settings.
To the line and level of
the NVELOPE proles in
relation to each other.
To the number of screws
and their position in each
NVELOPE bracket.
Cassette Hangers
The position of the cassette hangers should align with the fabricated 'hook' cut out
slots in the back of the cassette panel.
Horizontal datum lines should be projected across the elevation and the position of
the hangers should be marked on both anges of each vertical cassette prole.
Hangers are then placed in position on the prole and slid to their required position.
A SR2 4.8mm x 19mm screw is used though the hanger through the slot then
nal alignment can be made with the nal screw xed through the hole to lock the
hanger in position.
Cassette Panels
Cassettes should be fabricated to suit
the NVELOPE NV7 system designs (see
NVELOPE drawings for details).
Importantly the punched 'hanger'
cut out and the top and bottom folds
are critical to the installation of these
cassettes on to NVELOPE NV7 system.
The number of hangers and their vertical
position will be specied to suit the size
of the cassette panels and the dynamic
wind pressures (positive and negative).
Insulation
Where insulation is specied, it should be cut and tightly butted around the
brackets and secured with the appropriate xings. Sucient insulation xings
should be provided to ensure that the insulation cannot block the ventilated cavity
Cassette Panel Installation (General)
Fold back any protective cover along the four edges of the cassette panel just
prior to installing – where possible this protection should remain on the cassette
panel surface until an area of panelling has been completed and the possibility of
accidental damage is reduced.
Check prole and hanger positions in relation to actual cassette panel.
Raise cassette panel and support in vertical position.
Lower on to hanger plate and check that all 'hook' cut outs have engaged.
Drill rivet/screw hole in top corners and secure panel in nal position.
Check that the 'hook' cut outs are still engaged on the cassette panel.
