To promote builCling durability, the exterior wall envelope shall. be installed in a manner that water that enters the assembly can drain to the exterior. The envelope ~I..~isttli an exttriQP ~eneer, a water-resistive barrier as required in R703.2, a minimum 1/8 ill,C s~i1Ce b~tween tCe w<O:er-resistive barrier and the exterior veneer, and integrated flashings as .re~ire"in"l\103.8. iile r9q.uired 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 the 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 self-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 complying with section R703.2. 4. A space is not required where the exterior veneer is matching an existing exterior finish as in additions, alterations, or repairs. 5. A water-resistant exterior wall envelope shall not be required over concrete or masonry walls designed in accordance with Chapter 6 and flashed according to section R703.7 or R703.8. 6. Compliance with the requirements for a means of drainage, and the requiremen~s of Section R703.2 and Section R703.8, shall not be required for an exterior wall envelope that has been demonstrated to resist wind-dri~en rain through testing of the exterior wall envelope, including joints, penetrations and intersections with dissimilar materials, in accordance with ASTM E 331 under the following conditions: 6.1. Exterior wall envelope test assemblies shall include at least one opening, one control joint, one wall/eave interface and one wall sill. All tested openings and penetrations shall be representative of the intended end-use configuration. 6.2. Exterior wall envelope test assemblies 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 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 wall envelope; joints at the perimeter of openings penetration; or intersections of terminations with dissimilar materials.
