Toughened glass shall be horizontally toughened on Tam glass produced by subjecting
ordinary (annealed) glass to heating followed by rapid surface cooling, which produces high
compression in the surface of the glass. To break this glass requires a force strong enough to
overcome the compression in the surface in addition to the normal breakage strength of
the original annealed glass. Toughened glass is up to five times as strong as ordinary glass in
resisting impact, and is also considerably more resistant to dramatic changes in temperature.
When it breaks, toughened glass fragments into small, comparatively harmless pieces. It
cannot therefore be cut to size and should not be drilled, surface worked or edge worked;
extra care must be taken to order the correct size required for glazing.
Before installation the contractor shall ensure that :
all glazing rebates are square, plumb and true in plane, clear, dry and dust free;
all frame adjustments are made prior to glazing;
all glass edges, are clean cut to exact sizes, allowing expansion tolerance as
recommended by the glass manufacturer;
all sashes shall be glazed in the closed position and shall not be opened until the
compound is set;
all materials are to be used in strict accordance with the manufacturer's
glass shall not be forced into place;
Upon the completion of the work all glass shall be thoroughly cleaned, paint or other marks
removed. Any cracked, scratched, chipped or other defective glass shall be removed and
replaced without cost to the owner. Any loose glass shall be set to the satisfaction of the
The contractor shall replace all broken, damaged & disfigured glass before acceptance of the
building, at no extra cost to the owner.
