TECDUR
Glass Protection Ballistic utilises a clear resin that
is poured between an outer and inner surface of glass polycarbonate.
The thickness of the glass, resin /polycarbonate and the means
of attachment determines the performance level of the protection.
Weight
Tecdur Glass Protection Blast has a hidden strength which allows
it to absorb much of the blast loading. It utilises a unique
and patented attachment system that holds the window in the frame
and absorbs much of the impact of the blast.
 Clarity
At the higher level of protection typical glass or glass/polycarbonate
laminates lose clarity and exhibit a green tinge which often
makes armoured cars distinctive. Tecdur glass has a light transmittance
of 85% to 90% whereas similar protection with a glass/glass laminate
would typically be as low as 60%.
Level of spall
Tecdur glass forms a chemical bond with the glass, either normal
or toughened. When a traditional laminated blast window is subjected
to a level of blast, which causes the glass to deflect and break,
there is a significant amount of spall. This does not occur with
Tecdur and thus it is well suited to situations where large numbers
of people or sensitive electronic systems are located.
Loading
The hidden strength of the system and the unique and patented
means of attachment mean that a lighter frame can be used and
that lower levels of loading are placed on the wall. In extreme
cases Tecdur Glass Protection can be incorporated with Tecdur
Wall Protection.
Specifications will be drawn up based on the nature of the threat
and specific customer requirements such as size of window and
the need for discrete or visible protection.
