Weight
Tecdur® Blast Protection Glass 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 glass in the frame and absorbs much of the impact of the blast.
Clarity
At the higher level of protection typical glass/glass or glass/polycarbonate laminates lose clarity and exhibit a green tinge which often makes armoured glass distinctive. Tecdur glass has a light transmittance of 85% to 90% whereas similar protection with a glass/glass laminate would result in light transmissions be as low as 60%.
Level of spall
The resin used to produce Tecdur® forms a chemical bond with the glass, whether annealed or toughened. When a traditional laminated glass is subjected to a level of blast causing it to deflect and break, there can be a significant amount of spall (broken glass thrown off the inner face).Due to the chemical bond spall is significantly reduced 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 window frame can be used and that lower levels of loading are placed on the wall. Tecdur® Glass Protection can be incorporated with Tecdur Wall Protection.
Extended Temperature Range
As the resin cures with minimal shrinkage and the resin and glass share similar coefficients of expansion, there is a reduced stress in the bond. In addition as a chemical bond is formed, rather than a weaker physical bond typical in other systems an extended temperature performance range is achieved. For example, at minus 17 degrees Celsius it continues to protect where most glass/polycarbonate systems would fail.
Specifications will be drawn up based on the nature of the threat and specific client requirements such as size of window and the need for discrete or visible protection. |
