The vented and drained cavity formed by the Panel can be used for
applications other than EIFS.
Masonry veneer.Many
types of stone used for veneer make construction of an unobstructed
cavity behind the veneer difficult. The usual solution is to
use a rigid fibrous panel to fill the cavity and support the
veneer until the mortar has set. Another solution is to place
pieces of rigid plastic foam insulation intermittently in the
cavity, to be removed after the mortar has set. Neither solution
is entirely satisfactory. Fibrous insulation provides drainage,
but allows water to bridge the cavity and restricts ventilation.
Intermittent supports still leave mortar bridges across the
cavity, and sometimes are so difficult to remove that they
are left in place. Stucco Rainscreen Panel™ System, placed
against the primary insulation provide drainage, ventilation,
and, pressure-moderation — as well as support for the
veneer during construction.
Other cladding. With other cladding materials, pressure-treated
wood strapping is sometimes used to create a cavity. Korax
panels offer a simpler, but equally effective alternative.
For cladding other than stucco, the Panels placed nibs-out
and inverted, covered with building paper and wood or vinyl
siding would provide a drained pressure-moderated cavity, and
add thermal resistance to the wall.
The Panels are made from aged Type 1 Polystyrene board. Although
made primarily for use in EIFS, they might well be used for subgrade
drainage adjacent to foundations, or for ventilation under pedestrian
traffic surfaces over inverted roofs.
