Astra-Glaze-SW ™ Glazed Block
GLAZED STRUCTURAL MASONRY THAT IS BRIGHT AND HYGIENIC

Astra-Glaze-SWTM glazed blocks are the clean, bright,
simple and effective solution for creating broad areas of glazed
walling without the need for tiling. With
Astra-Glaze-SWTM 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-SWTM 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-SWTM 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-SWTM 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-SWTM 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-SWTM is manufactured to ±1.6mm for face
dimensions.
Water Absorption
Astra-Glaze-SWTM
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-SWTM 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.


The reproduction of colour is as close as possible within the photographic processess. It is advised to order samples prior to construction.
