The following picture also demonstrates the toughness and energy dissipation characteristics of SUBSTIWOOD products. Several 40-caliber bullets were shot at one of our 2-inch-thick paver units from a distance of approximately twenty feet. None of the bullets exited the paver and there was no shattering of the Substiwood paver.   The back of the test paver did not show any indication of the bullet impact.

Bullets lodged in 2-inch-thick Substiwood paver without shattering.
