2
What is it?
  • Unidirectional Armor
  • Allows return fire through the glass while
    protecting from hostile fire
  • Also available for stationary buildings

3
What is it made of?
  • A series of
  • polycarbonate
  • acrylic
  • glass layers merged in a special manufacturing
    process
  • Held together by a proprietary compounds of
    special glue or resin compounds

4
Benefits
  • Lighter
  • small cross section profile
  • extremely low distortion
  • clarity level of up to 90

5
How does it work
  • PROTECTIVE SIDE
  • When bullet strikes the acrylic outer layer, it
    compresses, strengthens, and absorbs/distributes
    the energy.
  • The polycarbonate layer stretches as it
    dissipates the remaining bullet energy with no
    full penetration
  • Spider webbing occurs on impact side, but inside
    glass remains undamaged
  • ONE WAY SIDE
  • Polycarbonate material compresses, acrylic
    stretches
  • Bullet passes through soft polycarbonate layer
    and into acrylic layer which weakens as it
    stretches
  • Bullet shatters acrylic, continuing with no loss
    of velocity or deflection
