Components
One vertical cassette prole is supplied. The prole is supplied without the foam
tape tted and this should be tted in position after cutting proles to length
NVELOPE brackets are supplied in dierent sizes ranging from 60 – 300mm (see
table below for cavity depths that can be formed).
NVELOPE brackets are available with hole-sizes 11 or 6.5 depending on the
diameter of the primary anchor/substrate type. If in doubt please contact technical.
Horizontal hangers for the cassette panels are secured in position with two
4.8mm x 19mm self-drilling self-tapping screws.

Cassette.
NVELOPE NV7 proles and
components are designed
to provide a vertical support
framework to 'hook' 3mm or
4mm thick cassette panels
to any suitable building
façade. These proles are
anchored to the building
using a purpose designed
bracket that allows nal
alignment and adjustment.

Brackets & Primary Fixings.
NVELOPE | Method Statement — Installation Guide NV7.
NVELOPE system brackets
are secured directly to a
new or existing substrate
of concrete, brickwork or
blockwork or steel frames.
Suitable primary anchors
are employed to position the
brackets to a pre-determined
grid to suit the cassette
panel layout.

Vertical Proles.
NVELOPE | Method Statement — Installation Guide NV7.
Vertical Proles
Once a column of vertical brackets is installed, the cassette prole can be attached
at each bracket position. (As the cassette panels will follow any irregularity or
miss-alignment of proles, it is important that time is taken to align/level the
framework to a high standard).
Each cassette prole should be cut to the required length.
Secure the prole using screws in the 'hole' or 'slots' in the NVELOPE bracket.
Move the prole into its vertical position – allowing 10mm 'expansion' between
proles.
The prole can then be eased outwards to form the specied cavity depth.
Check for line and level – then x the screws.
Important
As each cassette prole is secured
to the NVELOPE bracket ONE
connection, near the centre of the
prole, MUST be connected with
TWO SR2 4.2mm x 16mm stainless
steel xings going through the round
HOLES. (Fixed point) ALL other
bracket connections for the prole
should then be made in the TWO
SLOTS (sliding point).

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.
