A space is not required where the exterior veneer is installed over a water-resistive barrier
complying with section R703.2 which is manufactured in a m~nner to enhance drainage ,and
meets the 75% drainage efficiency requirement of ASTM E2273 or other recognized
national standards. .
A space is not required where window sills are equipped wi,th pan flashings.which drain to
the exterior surface of the veneer in a through wall fashion: All pan'flashings shall be
detailed within the construction documents and shall be of either a self-adhering

pounds per square foot.
6.4. Exterior wall envelope assemblies shall be subjected to a 'minimum test exposure
duration of 2 hours. \; ,
The exterior wall envelope design shall be considered to resist wind-driven rain where the
results of the testing indicate that water did not penetrate: control joints in the exterior .
