FEATURES
AND APPLICATIONS
 toughened
safety glass is a Grade A safety glass as per AS1288;
up
to 500% stronger than annealed glass and therefore
is more resistant to thermal breakage and can withstand
greater windloads;
on
breaking it fragments into many small harmless pieces unlike
annealed glass;
can
be used within a temperature range of minus 70degC to plus
300degC (surface temperature should not exceed 250degC if
other surface is lower than 0degC ambient);
standard
arrissed edge makes handling easier;
ease
of matching tinted toughened and tinted annealed glass;
plastic
wrapped to avoid scratches during delivery or on site;
recommended
for door, side and low lites, frameless entries, balustrades,
shower, bath screen panels and furniture;
flat
automotive toughened and marine toughened is available in
3 - 8mm thicknesses. Other thicknesses are available on request;
available
in thicknessess 3 - 25mm.
DID
YOU KNOW?
toughened
glass cannot be drilled
or edgeworked in any manner. Sandblasting or other surface treatments should
be carried out prior to toughening as per AS1288 - 1994. Deep sandblasted
patterns greater than 1mm are not permissible;
toughened
glass ordered to templates must be accompanied with a full scale template
made to the correct dimensions. These must be made from a rigid material.
Orders submitted with complex drawings and sizes to avoid template construction
will either be rejected or executed at the customer’s risk;
minimum
edgework finish on toughened glass up to 12mm is a standard
arrissed edge. Minimum edgework on greater thicknesses should
be a flat ground edge;
slight
distortion or bowing may occur after toughening but is largely
controllable. It will vary with substance, tint, surface
treatment, size and shape of the glass. Ceramic painted,
sandblasted or reflective coated glass has a greater tendency
to bow and special tolerances would be advised. Flatness
will be measured when the glass is standing on edge with
a straight edge placed along the full length of the panel
and a wedge measurement taken at the centre position. Refer
to our technical department for more information;

Toughened entry doors glazed by Graphic Glass.
the
roller motion process during the furnacing of glass
panels can produce slight corrugated distortion or
roller waves. This visual effect is in the form of
distortion bands 250 - 300mm apart. It is most noticeable
in reflective toughened glass and should be glazed
horizontally;
not
recommended for overhead glazing and structural balustrades
with no hand rails above ground floor;
plastic
wrap on toughened glass should be removed no later than
one month after exposure to sunlight.
