Special Installation Considerations
Stucco**
When stucco is installed over wood-based sheeting the 2006-IBC (section 2510.6) and the 2006 IRC (section R-
703.6.3) require “a water resistive barrier with a performance at least equivalent to two layers of Grade D paper”
or a layer of water resistive barrier (WRB) which is separated from the stucco by an “intervening layer”. When
Typar® WRB is used behind stucco it should be separated from the stucco by a second layer of Typar® WRB, a layer
of Grade D building paper or the Grade D paper backing of paper-backed lath.
Brick**
The 2006 IRC (section R703.7.4.2) requires a min 1” (25mm) airspace separating the brick from the WRB. The Brick
Industry Association recommends a 1” (25mm) air space in front of the wood stud construction and a 2” air space
in front of a steel stud construction.
Stone Veneer**
The 2006 IBC (Section 1405.6) requires two layers of WRB behind stone. Over wood frame construction, Typar®
WRB should be installed behind stone the same way as installed behind stucco.
Wood Siding**
Typar® WRB and wood siding must be installed according to the manufacturer’s instruction and the industry
standards. Wood industry association recommends siding should be primed before installation.
** Typar® recommends that the installation of any material must first follow the local applicable building
codes.
