The following video demonstrates  the shatter resistance of our SUBSTIWOOD^® material. Move the mouse over the picture to start the video. A thin piece of Substiwood (with variable thickness of less than 1 inch) is dropped onto a concrete surface twice without shattering. Can you do this with any other conventional or non-conventional concrete product?

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.
