[Section R703.1.1 is provided for reference on the reverse side of this form.] #'lr-~4~ Signature' ~ j--Y-/ / Date &d/ ~/ CJL{/-70t5~c57a / Revised: 2/8/2010 " '-,... ,." ..4 " Excerpt from 2008 Oregon Residential Specialty Code Section R703, Exterior Covering: R703.1.1 Exterior Wall Envelope. To promote buil~;ng 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 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. 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 flashing~ 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 materia.! or' I" 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. 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. A space is not required where the exterior veneer is matching an existing exterior finish as in additions, alterations, or repairs. 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. Compliance with the requirements for a means of drainage, and the requirements of Section R703.2 and Section R703.8, shall not be required for an exterior wall envelope that has been demonstrated to resist wind-driven 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. Exterior wall. envelope test assemblies shall be at least 4 feet by 8 feet in size. 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 resuFts 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. ~ " 2. 3. 4.
