To promote builaing durability, the exterior wall envelope shall be installed in a manner that water that enters the assembly can drain to the exterior. The envelope shall consist of an exterior veneer, a water-resistive barrier as required in R703.2, a minimum 1/8 inch space between the water-resistive barrier and the exterior veneer, and integrated flashings as required in R703.8. The required space shall be formed by the use of any non-corrodible furring strip, drainage mat or drainage board. The envelope shall provide proper integration of flashings with the water-resistive barrier, the space provided and the exterior veneer. These components, in conjunction, shall provide a means of draining water that enters the assembly to t~e exterior. Exceptions: 1. 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 manner to enhance drainage and meets the 75% drainage efficiency requirement of ASTM E2273 or other recognized national standards. 2. A space is not required where window sills are equipped with 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 s'elf~adhering - \ membrane complying with AAMA 711-07 or of an approved corrosion-resistant material or a combination thereof. Self-adhering membranes extending to the exterior surface of the veneer shall be concealed with trims or other measures to protect from sunlight. 3. A space is not required where the exterior veneer is manufactured in a manner to enhance drainage and meets the 75% drainage efficiency requirements of ASTM E2273 or other recognized national standards and is installed over a water resistive barrier compiying with section R703.2. . , 4.

Exterior wall envelope test assemblies shall include at least one opening;one'co!'trol\ \ joint, one wall/eave interface and one wall sill. All tested openings and penetr~tions\ shall be representative of the intended end-use configuration. 6.2. Exterior wall envelope test ass"mblies shall be at least 4 feet by 8 feet in size. 6.3. Exterior wall assemblies shall be tested at a minimum differential pressure of 6.24 pounds per square foo.t. 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 wall envelope; joints at the perimeter of openings penetration; or intersections of terminations with dissimilar materials.
