structural integrity.
Water, Freeze and
Thaw Resistant
VIROC is stable when subjected to water immersion without any
sealant applied to the board. It will not delaminate in water
and is dimensionally stable.
Impact Resistant Test results of ASTM D-256 indicate that VIROC is capable of
successfully resisting substantial impact forces without
experiencing breakage or fissuring.
Sound Resistant
Acoustic Performance
As a result of its mass, VIROC offers excellent sound attenuation.
