Exterior Cement Board Cladding
Viroc is a composite material, composed by a compressed and dry mixture of pine wood particles and cement. It combines the flexibility of wood with the strength and durability of cement, allowing a large range of applications, both indoor and outdoor. Viroc presents a non-homogeneous appearance, a product natural feature. Viroc can be factory calibrated/sanded (for applications requiring tighter tolerances). Once calibrated, presents visible wood particles on the surface.
Advantages of Cement Board
Your Best Defense Against Termites.
stands Lip to more than weather, fire and thaw. This
exceptional cement bonded particle board resists one
of the most dreaded and costly threats any homeowner
faces - termites.
prove it, Allied Building Products commissioned the
University of Hawaii at Manoa to test VIROC's termite
resistance. We didn't pit it against just any termite.
We chose the most destructive species on 3 continents;
Formosan subterranean termite.
termites will eat through metal, plastic and asphalt
to get to anything that contains wood fiber. Ten times
more voracious than native termites, Formosan colonies
can consume a half ton of wood a year.

14 states, Experts predict that number to rise.
already spend nearly $2 billion annually to eat and
repair Formosan termite damage. We knew if VIROC could
withstand these monsters, then no termite could overpower
the extensive testing, wafers cut from standard VIROC
panels and Douglas fir were evaluated. The top and bottom
water surfaces were finished smooth. The cut edges were
unfinished and rough in appearance.
sample was exposed to 400 Formosan termites every day
for 28 days. The results were nothing short of astounding.
virtually destroyed the Douglas fir wafers over the
four weeks. However, VIROC wafers showed either no attack
or minor superficial attack only to the cut ends.
Douglas fir wafers lost at least half their original
weight to the Formosan termite attacks, VIROC wafers
actually gained weight due to slight moisture uptake,
However, unlike other composite materials that absorb
moisture, VIROC's dimensions and structural integrity
remained consistent and strong.
Would Rather Die Than Feed On VIROC
a no-choice test where termites were forced to feed
on VIROC or die, termite mortality was more than twice
that of the groups feeding on Douglas fir, and all the
soldier termites (who must be fed by worker termites)
died in the VIROC No Choice test.
evidence is clear and documented. VIROC is your safest,
most cost-effective, weapon against termites
