In the field of high-stakes security, protection is measured not just by what a material can stop, but by what it prevents from happening. While stopping a bullet or absorbing the initial force of a blast is essential, the secondary threat—the deadly fragments of glass known as spall—often poses the greatest risk to occupants.

At Kratos Glass, our advanced glazing solutions are engineered to counter this lethal hazard through the integration of sophisticated Anti-Spall Technology.

Hi

On page 9 of above referenced article the ultimate strength of spacers is called out as 8-10 GPa for 'as received glass', 6-7 GPa 'after annealing of glass' and 1-2 GPa for stainless steel spacer. My understanding is that the ultimate compressive strength of glass is some 1000 MPa = 145,000 psi if no tension is induced. Are not the values of 2 to 10 GPa then completely irrelevant? Could anyone explain?

Thank you

Best Regards

Hi, I'm new to this forum. I work for a transparent armor company and am investigating the high number of window failures during final inspection. The issue seems to be small debris, both on and under the polycarbonate layers. I'm wondering if anyone has experience with the lamination process for ballistic glass and, specifically, any issues with the protective film on the polycarbonate?

Troubleshooting SGCC Laminated Glass Ball Drop Test Failures – ASTM F3007 Help

We’ve been running into a frustrating issue at our facility and are hoping someone in the community has dealt with this or can offer insight

.

We’re currently performing in-house ball drop impact testing on laminated glass according to ASTM F3007-13, as part of SGCC production testing requirements. This test uses a 2.3 kg (5 lb) steel ball dropped from 3.66 meters (12 feet) for Class A products.

Hello everyone, I'm facing an issue with laminated glass  used in a laser machine door. 

The glass consists of two layers ( 4mm+4mm) with a black film in between. 

Recently, small transparent dots have appeared, almost as if the film is degrading or dissolving , and the glass looks foggy up close. 

Does anyone have any idea about the cause or a solution for this problem?

 Hi new to this forum.  If anyone in Toronto area that needs service work on there 60 inch vertical washer please contact.  

A few months ago a customer contacted us about a mildew issue under the silicone on their frameless shower.  The shower was older; probably installed in the 1990s. 

My technicians went out, disassembled the shower, cleaned the glass and tile with a clorox cleaner.  They said they ate lunch after cleaning to allow time for the cleaner to dry up.  They put it all back together using a mildew-resistant silicone from CR Laurence and told the customers not to use the shower or get the silicone wet for at least 24 hours.
