Installation information
Depending on requirements, Speedwall can be installed
horizontally or vertically. The first step is to fix C Track around
the perimeter of the wall. In some situations, Angle sections
are used instead of C Track for ease of installation.
C Track sections come in a standard profile with a 60mm
nominal flange. When C Track is fixed to a concrete floor, it
must be isolated from the slab by using fire rated sealant, to
smooth out any irregularities in the surface of the concrete.
C Track and Angle sections are normally 3600mm long and
should be fixed at not more than 400mm centres (unless
specifically designed).
Fixings should be placed within 100mm from the end and
should be specifically designed for loadings.
For fire and acoustic rated walls, the C Track or Angle section
must have a bead of fire resistant sealant between it and the
structure it is being fixed to.
Cutting of Speedwall panels
Speedwall panels can be cut to length with the use of a
Sabre saw or Evacuated grinder to minimise dust.
Where Speedwall panels are trimmed to width, the cut
section of the panel is fitted with C Track and is always the
last panel abutting the wall, column or soffit. The panel is
then sealed and fixed in position.
Horizontal installation
Horizontal Installation of the Speedwall panels requires C Track
to be fixed to structural walls, columns, portals etc.
To ensure tightness of fixture, a 15mm bead of fire resistant
sealant is run around the perimeter before the C Track or Angle
sections are laid and fixed.
Grout is poured into the floor C Track just prior to the installation
of the Speedwall panels. This forms a bearing surface for the
female end of the panel and is also a fire and acoustic rated seal.
The cementitious grout should be non shrink high performance
(Hilti® CM651-48). Fill the C Track to a depth of 25-30mm. Any
overflow when the panel is placed in the C Track must be wiped
off immediately.
Ensure that the first panel is level after fitting into the C Track
and grout. Screw fix panel to C Track.
Subsequent panels are placed in a tilt and snap action.
Last panel
To get the last horizontal panel in, the C Track is cut on one
side approximately 400mm from the top of the wall.
The tab is folded back to allow entry of the last panel.
Fire resistant sealant is applied. The angle is then fixed to
the soffit and panel.
Corners
Where internal or external corners are required, panels
should be finished by fixing C Track to the vertical face.
C Track should also be fixed to the side of the finished wall
channel. Fire resistant sealant must be used between the
C Tracks. Fixing between C Tracks should be at 300mm
centres.
Vertical installation
Vertical installation of the Speedwall panels requires
C Track to be fixed to walls, columns and soffits etc.
To ensure tightness of fixture, a 15mm bead of fire resistant
sealant is run around the perimeter before the C Tracks or
Angle sections are laid and fixed.
The first panel is placed inside the C Track (slightly tilting
back) and is slid into the vertical position. The first
panel is levelled and then fixed into position. Panels push into
place respectively until the wall is nearly completed.
Last panel
Stop short of the end vertical Speedwall C Track by
approximately 1 metre and cut out a 600mm angle section
from the top and bottom C Track. Plan ahead and make an
allowance for a 50mm overlap onto the panels installed prior
to the last remaining two panels.
Make your end cut ensuring that a distance of 500mm
remains for the last two panels to be squeezed into position. Once in postion, simply replace the angle and fix to
panels. Screw the C Track and Angle sections to the panels in
the normal fashion.
Doorways and windows
C Track is cut to the trim size for doors, windows and large
penetrations. As the wall is assembled the C Track is fitted
and sealed and fixed as per the standard details.
An engineer must ensure that wind face load and panel self
weight loads can be transferred at wall openings.
Penetrations
Where penetrations into Speedwall are required, the use of
a grinder, Sabre saw or hole saw to remove the steel shell is
ideal. The aerated concrete is easily removed.
Any gaps in, or services that penetrate through fire rated
construction are to be fire rated using certified proprietary
systems such as fire collars, fire wraps, intumescent systems
etc. The systems are to be installed as required by the
certification and manufacturer of the product.
Speedwall should be earthed where electrical equipment or
unsheathed cables may come into contact with the metal work.
Plumbing and electrical services
Copper and brass piping should be isolated from direct
contact with the steel shell. Similar care should be taken
when contact with dissimilar metals is possible.
Shelf loads
Speedwall can be used to carry shelf loads. The capacity of
Speedwall to carry shelf loading is dependant upon variables
such as shelf design, shelf fastening methods, wall height and
shelf location.
Fixing accessories
Where practical, services and accessories should be fixed
through the male / female shell connections, where the steel
shell has greatest thickness (1.2mm B.M.T.).
Where loads are higher e.g. 50 x 50 timber framing for an
internal gutter, fixings should extend through the panel.
External wall installation
Speedwall is designed for internal non load bearing walls.
For external walls, we recommend that Speedwall should be
clad with an external weather proof system eg. a profile metal
cladding. Speedwall (NZ) Ltd can provide site specific details.
