4 The exterior wall envelope shall be designed and constructed in such a manner as to prevent the accumulation of water within the wall assembly by providing a Water-Resistive barrier behind the exterior veneer, as described in Section , and a means for draining water that enters the assembly to the exterior. The exterior wall envelope shall include flashing, as described in Section DuPont Building Envelope Solutions Products for commercial construction have been tested to the following standards: ABAA Evaluated ASTM E 2357 Standard Test Method for Determining Air Leakage of Air Barrier Assemblies ASTM E 1677 Standard Specification for an Air Retarder (AR) Material or System for Low-Rise Framed Building Walls ASTM E 331 Standard Test Method for water Penetration of Exterior Windows, Skylights, Doors, and Curtain Walls by Uniform Static Pressure ASTM E1105 Standard Test Method for Field Determination of water Penetration of Installed Exterior Windows, Skylights, Door, and Curtain Walls, by Uniform or Cyclic Static Air Pressure Difference ASTM E 2178 Standard Test Method for Air Permeance of Building Materials ASTM E 283 Standard Test Method for Determining Rate of Air Leakage Through Exterior Windows.

6 CCRR-0307 for DuPont Tyvek Fluid Applied WB+ Special Considerations1. High performance installations are defined as building envelope design requirements that exceed ASTM E1677, 65 mph equivalent structural load and 15 mph equivalent wind-driven rain water infiltration Tyvek CommercialWrap D must be installed with the grooves going up and DuPont requires that Tyvek CommercialWrap and Tyvek CommercialWrap D be covered within nine (9) months (270 days) of DuPont Self-Adhered Flashing Products should be installed on clean, dry surfaces that are free of frost. Wipe surfaces to remove moisture, dirt, grease and other debris that could interfere with DuPont requires that DuPont FlexWrap , DuPont FlexWrap EZ, DuPont StraightFlash , and DuPont VersaFlange be covered within nine months (270 days) of installation. DuPont requires that DuPont Flashing Tape be covered within four months (120 days) of DuPont Self-Adhered Flashing Products are not intended for through-wall flashing When using mechanically fastened through-wall flashing, DuPont recommends sealing top edge with StraightFlash.

7 8. No surface preparation is needed for the installation of Tyvek Adverse weather conditions or cold temperatures may require use of a primer to promote adhesion of DuPont Self-Adhered Flashing Products to most common wood-based building materials. Concrete, masonry, and fiber faced exterior gypsum board require the use of DuPont Adhesive/Primer, or recommended primer. Do not apply DuPont Adhesive/Primer, or recommended primer, to exterior continuous insulation due to potential sheathing DuPont Self-Adhered Flashing Products perform best when installed at temperatures above 25 F ( 4 C).11. Before applying 3 DuPont Tyvek Tape, surfaces should be dry and clean. During installation apply firm, even pressure with hand or J 4 DuPont Flashing Tape is an alternative to 3 Tyvek Tape where Remove all wrinkles and bubbles that may allow for water intrusion by smoothing surface and repositioning as necessary during installation of DuPont Self-Adhered Flashing Products.

8 Apply pressure along entire surface of flashing for a good bond using firm hand pressure, J-roller, or alternate tool without sharp edges (such as a plastic carpet tuck tool) to assist with application of uniform High performance installations require StraightFlash , DuPont Flashing Tape or recommended alternate patches behind fastening plates (brick tie base plates, metal fastening clips, metal channels, etc.). When used behind the cladding fasteners and/or fastening plates, the flashing patch must be adhered to the Tyvek Tyvek Fluid Applied Products should only be used for wall systems that include a continuous path for drainage allowing moisture that penetrates the facade to exit to the exterior. The drainage path should be continuous throughout the wall assembly, including but not limited to areas such as eyebrows, band boards, penetrations, or other locations where transitions and changes of plane occur.

9 For membrane drainage wall systems, ensure that the drainage path is not blocked or disrupted to prevent excess moisture buildup in the wall Suitable substrates for Tyvek Fluid Applied Products include concrete masonry unit (CMU), concrete (48 hrs. for green concrete), exterior gypsum, OSB, plywood, wood, and metal. Contact your local DuPont Tyvek Specialist for use with pressure-treated or fire-retardant-treated wood (FRT).17. Uncured Tyvek Fluid Applied Products must not come in contact with building wraps due to potential impact on performance Tyvek CommercialWrap and Tyvek CommercialWrap D may be installed over Tyvek Fluid Applied Products after 48 hours of curing at 70 F (20 C) and 50% When Tyvek Fluid Applied Products are used as the air and water barrier, Tyvek WRBs may be installed as an intervening layer over Tyvek Fluid Applied Products after 48 hours of curing at 70 F (20 C) and 50% RH.

10 For additional information about the use of intervening layers see the Stucco section under Facade/Exterior DuPont recommends the use of Tyvek Fluid Applied Products for CMU walls with embedded brick ties.

DuPont Tyvek CommercialWrap and Tyvek CommercialWrap D must not come in direct contact with other manufacturer s cured or uncured fluid-applied and/or deck coating waterproofing products due to potential impact on performance properties. DuPont StraightFlash can be used as transitional The maximum in-service temperature for DuPont Tyvek WRBs, DuPont Self-Adhered Flashing Products, and DuPont Tyvek Fluid Applied Products is 180 additional guidance, please call 1-833-338-7668, visit our website at , or consult your local DuPont Tyvek Installation Requirements for DuPont Tyvek Water-Resistive and Air Barriers (WRBs)ContinuityIt is important to maintain the continuity of the DuPont Tyvek WRBs throughout the building envelope.
