High Performance Systems
Blast-Resistant Glass Block Panels

Makes Threats Less Threatening – By Making Impacts Less Impactful

  • Greater security than conventional windows
  • Enhanced protection for building occupants
  • Meets GSA and UFC 04-010-01 blast glass standards

Our patent-pending blast-resistant panels have been designed and tested to meet and exceed stringent government, military and international building requirements to give you the beauty of glass – with the utmost protection.

Many injuries to building occupants are caused by glass fragments sent flying through the air from the force of a blast. Unlike laminated flat glass, which will often crack and sometimes release fragments during a blast, there was no cracking or loss of glass in the tests conducted on our Blast-Resistant Glass Block Panels.

Blast-Resistant Glass Block Panels

Blast-Resistant Glass Block Panels let in light, while providing privacy and protection from various levels of blast. They are the perfect choice for high-risk buildings such as military facilities, airports, government offices, embassies, courthouses, correctional facilities, arenas, financial centers, offices and other high-profile public and retail spaces.

System Security Features

  • Meets GSA and UFC 04-010-01 blast glass standard
  • No cracking or loss of glass during testing
  • Offers enhanced protection to building occupants
  • Provides greater security than conventional windows

Engineering analysis supplemented with shock tube testing performed by an independent laboratory has determined that Blast-Resistant Glass Block Panels with sizes ranging from 4' x 4' to 8' x 8' perform to an ASTM “minimal Hazard” or GSA “Performance Condition 2” or better for:

  • General Services Administration (GSA) Level C and Level D
  • Unified Facilities Criteria (UFC) DoD Minimum Antiterrorism Standards for Buildings Type I threats at 25m and 45m standoff distances and Type II threats at 10m and 25m standoff distances
  • For Petrochemical applications, a successful blast test of longer duration was also performed

Smaller and larger windows are available. Contact Pittsburgh Corning for more information.

System Facts

Blast-Resistant Glass Block Panels consist of glass block framed by a 2-piece aluminum channel. Standard channel is mill finished, anodized clear or bronze. Powder coating is also available.
