Light weight and accurate
A 12 m x 3m x 120mm reinforced concrete wall panel weighs over
10 tonne. A similarly sized Gypcrete wall panel
weighs only 1.5 tonne. At only 42kg
per square metre a single B-double
truck can transport over 900 square metres of Gypcrete wall panel
compared to 125 square metres of 120mm thick precast concrete hollow
block work. Precision manufactured Gypcrete wall panels provide certainty in
calculations and in construction tolerances.
High quality finish
The finish of Gypcrete wall panel is smoother and
flatter than an equivalent precast concrete, insitu-concrete or rendered
Gypcrete wall panel provides the
ideal "green" structural walling material for contemporary
architectural designs. Gypcrete wall panels can
be finished in a range of decorative texture finishes and can
include bands, quoins, and rendered finishes. Gypcrete wall panel is a
strong, crack-free, clean and sharp structural grade wall panel requiring
less joining and less finishing.
Gypcrete wall panel has an installed cost
considerably less than that of an equivalent standard precast concrete wall.
Gypcrete wall panel costs less than equivalent strength
masonry walling over which it also enjoys
a 15% space saving. Because Gypcrete
wall panel is quicker and easer to erect projects are finished
faster and development funds are tied up for shorter periods. Gypcrete
wall panel can eliminate the need for bricks, blocks, timber
walls frames and plasterboard linings.
The unique cellular structure of the Gypcrete wall
panels enables it to be used as
left-in-place formwork and site-filled with concrete to provide
sufficient axial strength and lateral rigidity to
support buildings up to 15 storeys.
When used structurally Gypcrete wall panel eliminates the need for beam
and column framework. When filled with insulation only Gypcrete wall panel
can be used as load-bearing walling for timber floored residential
construction up to three storeys.
A Gypcrete wall panel is machine made in one hour.
The panels are generally manufactured in
one size then cut to dimension for height
and length complete with door and window
cut-outs. In a single day a
small crane and two trained installers can erect all the wall
sections for a medium sized 350 square metre house. The large
size of the Gypcrete wall panels also means fewer fully
sealed construction and contraction joints.
Gypcrete wall panel is made using plaster
manufactured from either naturally occurring gypsum, chemical gypsum or
waste flu-gas gypsum. Gypcrete wall panel has one of the lowest levels of
embodied energy of all known comparable
walling products. ("Embodied energy" is the total energy
consumed by the product from the point
of extraction of the raw material
through manufacture, processing and delivery to its final installation and finishing
on a building project.) Gypcrete wall panels are 100% recyclable. They
can be re-processed through our Rapidflow Calcination Plant and recast
into new Gypcrete wall panels.
Gypcrete wall panel has outstanding fire-resistant properties
making it an ideal building material for use in dwellings in
bushfire prone areas as well as in apartment construction where
fire-rated party walls are required.
Gypcrete wall panel is rated at one, two and four hours respectively
when empty, insulated and concrete filled.
When used as load-bearing shear walls
Gypcrete wall panel exhibits superior ductile qualities that make it safer
and effectively stronger than un-reinforced masonry. Its mechanical properties make Gypcrete
wall panel a superior earthquake resistant structural walling product for
both vertical and lateral loads.
Water and rot resistant
In an unsealed and uncoated state and after full
immersion in water for 24 hours the moisture uptake of Gypcrete
is less than 5% (by weight). Gypcrete wall panel is approved
for use in wet areas requiring only the application of
the normal mandatory wet-area membrane.
Gypcrete wall panels are made of
gypsum plaster and fibreglass. They are immune to attack from vermin
and termites. Gypcrete wall panel construction is devoid of any timber
products eliminating any risk of termite infestation for which there
are no safe prevention methods.
Good sound attenuation
Whether insulated or concrete filled
Gypcrete wall panel has excellent sound attenuating characteristics.
Gypcrete wall panel can be used as
structural party walls providing the basis
for an effective 55 STC sound barrier when lined with plasterboard
on resilient mounts. A rating of RW 55 can be achieved
using plasterboard lining on isolated studs on one side of
the load-bearing Gypcrete wall panel.
wall panel, when concrete or sand-filled,
is resistant to penetration by flying objects so common in cyclones.
Additionally a simple tie-down system passing through the Gypcrete wall panel
cells and into the foundation secures the roof against severe
uplift forces experienced in cyclones.
120mm wide, when compared to brick-veneer construction, Gypcrete wall panel provides
up to 10% more usable internal floor space of a
building of comparable external dimensions
