Astra-Glaze-SW®
GLAZED STRUCTURAL MASONRY THAT IS BRIGHT AND HYGIENIC
Astra-Glaze-SW is the clean, bright, simple and effective
solution for creating broad areas of glazed walling without the
need for tiling. With Astra-Glaze-SW glazed walling you can create
load-bearing or non-load-bearing walls with a strikingly beautiful
finish saving time, money and eliminating the risk of
delamination.
Astra-Glaze-SW units are medium density concrete blocks that have a
thermosetting glazing compound permanently moulded to one or more
of their faces. The glazed facings are moulded individually,
assuring
dimensional uniformity regardless of minor variations in the block.
When cured and heat-treated in kilns, the glazing compound becomes
an integral part of the unit.
Advanced manufacturing processes are used to provide a permanent,
impervious, satin glazed finish with exceptional resistance to
staining, abrasion, impact and chemicals.
A Lasting Solution
Astra-Glaze units are outstandingly
colourfast and the satin finish will last the lifetime of your
building, eliminating the need to repaint or refinish and ensuring
that it looks as good over time as you
originally intended. Graffiti, dirt, grime and grease can be
removed easily and Astra-Glaze is just as resistant to extremes of
weather, with built-in ductility to negate the possibility of
cracking or crazing in adverse conditions.
With a broad variety of components to co-ordinate with standard 400
x 200mm modules or the option of a 450 x 225mm co-ordinating range,
and a vast range of standard colours from which to choose, plus the
ability to specify your own shades and hues for larger projects,
Astra Glaze offers the ultimate in design flexibility.

Composition & Standards
Manufactured
in accordance with ASTM-C90 Type 1 (American standard)
Concrete Mix
Crushed aggregate and
cement
Facing Mix
High purity silica sands and resinous binder permanently bonded on
to block in a thermosetting process.
Concrete Block Density
1600kg/m³
Nominal Block Strength
7.3N/mm²
Thermal Conductivity:
0.51W/mk
Coefficient of Linear Expansion:
10.5 x
10-6/K
Dimensional Tolerance:
Astra-Glaze is manufactured to ±1.6mm for face dimensions.
Water Absorption
Astra-Glaze is impervious to
water penetration. Therefore, when joints are grouted correctly
with waterproof mortar (supplied by others), an impervious wall
finish can be achieved. Adequate ventilation should be provided in
areas of particularly high humidity.
Fire Resistance:
Astra-Glaze is manufactured with a class 1 fire rated aggregate The
facing material fully complies with and exceeds the strict
requirements of ASTM C90 for flame spread and smoke emission.
Cutting:
All cutting must be carried out on a bench-mounted clipper saw with
a continuous supply of clean water. The blade should enter the
glazed face first. All cut units should be thoroughly washed and
allowed to dry before use.
