Cement Board
Masonry Veneer Wall
System (CBMV)
For use in residential and low-rise
commercial applications, CBMV
offers a complete, engineered
solution for installation of adhered
veneers. It provides the ability to
incorporate an effective water-
management system for a variety
of building exteriors with manu-
factured or natural stone and thin
brick veneers.
Benefits Include

Engineered system that allows
a faster installation while
providing superior quality
control (manufactured product
that must comply with ASTM
product specifications)

Increased performance by utilizing
polymer modified adhesive mortars
(designed for hanging materials)
rather than type S&N mortars
(developed for stacking materials)

Extremely durable with
increased resistance to impact
and inclement weather

Approved for use in ASTM C 1780,
and cement board is cited as
an approved substrate for this
system by the Masonry Veneer
Manufacturers Association
(MVMA):
