Rev. 5/10 3 DuPont tyvek Weather Barrier Commercial Installation GuidelinesWeather Barrier & Energy Conservation Codes and StandardsThe 2009 International Building Code (Section Weather Protection) requires that exterior walls shall provide the building with a Weather resistant exterior wall envelope.

4 The exterior wall envelope shall include flashing, as described in Section DuPont tyvek Weatherization System products have been tested to the following standards. ASTM E 331 Standard Test Method for Water Penetration of Exterior Windows, Skylights, Doors, and Curtain Walls by Uniform Static Pressure ASTM E 2178 Standard Test Method for Air Permeance of Building Materials ASTM E 2357 Standard Test Method for Determining Air Leakage of Air Barrier Assemblies ASTM E 283 Standard Test Method for Determining Rate of Air Leakage Through Exterior Windows, Curtain Walls and Doors Under Specified Pressure Differences Across the Specimen. ASTM E 2556 Standard Specification for Vapor permeable Flexible sheet Water-resistive barriers intended for mechanical Conservation Codes for Commercial buildings are being adopted in many regions across the DuPont tyvek Fluid Applied Weather Barrier System products meet the following codes and Guidelines .

DuPont tyvek CommercialWrap D shall be installed with vertical grooves, going up and DuPont requires that DuPont tyvek CommercialWrap and DuPont tyvek CommercialWrap D be covered within nine (9) months (270 days) of its Installation .

6 DuPont tyvek ThermaWrap must be covered within four (4) months (120 days) of its No surface preparation is needed for the Installation of DuPont tyvek Weather Priming is generally not required for adhering DuPont Flashing Systems products to most common building materials. However, adverse Weather conditions or cold temperatures may require use of a primer to promote adhesion. Additionally, concrete, masonry, and fiber faced exterior gypsum board require the use of recommended primers. Consult your local DuPont tyvek Specialist for primer recommendations and recommended primers. DuPont Flashing Systems products perform best when installed at temperatures above 25 F ( 4 C).5. To claim the effective R-Value benefits of DuPont tyvek ThermaWrap it shall be installed with shiny, metallic side facing towards a clear inch minimum airspace.

7 Without an airspace, the effective R-value of DuPont tyvek ThermaWrap will be reduced or eliminated but DuPont tyvek ThermaWrap will still act as a Weather Before applying 3 DuPont tyvek Tape, surfaces should be dry and clean. During Installation firm even pressure should be used with the hand or J DuPont FlexWrap NF can be used in place of DuPont FlexWrap throughout this DuPont Commercial Sealant should be tooled flat to allow the natural curing process to create a concave DuPont Corners and DuPont End Dams are recommended as a best practice to be used with DuPont Thru-Wall Flashing. Alternatives can be used if it meets the design intent of the When high performance installations are required, DuPont StraightFlash or DuPont recommended alternate shall be used at terminations and as patches behind fastening plates (brick tie base plates, metal fastening clips, metal channels, etc.)

Starting at a corner of the building unroll DuPont tyvek Weather Barrier keeping the roll plumb. Extend approximately 12 past either the inside or outside corner of the Vertically overlap the next sheet of DuPont tyvek by at least 6 . Vertical grid lines have been provided every 8 on DuPont tyvek CommercialWrap to assist in alignment with stud : It is important that proper shingling is maintained.

9 DuPont tyvek Weather barriers should be installed from the bottom of the building up to ensure proper : Vertical Installation of DuPont tyvek CommercialWrap and DuPont tyvek ThermaWrap is acceptable. 6 overlap and proper shingling of vertical and horizontal seams is required. This Installation is not permitted for DuPont tyvek CommercialWrap 2 DuPont tyvek should overlap through-wall flashing* by a minimum of 6 . For maximum air leakage reduction (when installing as an air Barrier ), seal wrap at the bottom of the wall with sealant, DuPont tyvek Tape, or DuPont StraightFlash . (If no through-wall flashing* is being used, the bottom edge of DuPont tyvek should extend over the sill plate by at least 2 .)Note: Refer to DuPont Thru-Wall Flashing Installation Guidelines located on the web site or located in the Flashing Guide to properly integrate DuPont tyvek Weather barriers with the through-wall flashing.

10 *SteP 3 Secure DuPont tyvek Weather Barrier by fastening into the studs. For fastener type and spacing refer to the Recommended Fasteners and Spacing section of this : In order to keep DuPont tyvek from being damaged by cladding Installation , special attention should be taken to ensure that the DuPont tyvek is pressed tightly into any inside corners before 4 Unroll DuPont tyvek directly over windows and doors rough openings. Upper layer of DuPont tyvek should overlap bottom layer of DuPont tyvek by a minimum of 6 . Do not install fasteners within 6 of the sills and jambs of the openings and within 9 of the head of the tyvek will be fastened during flashing Installation . Refer to the Commercial DuPont Flashing Systems Installation Guidelines to prepare window and door 5 Tape all horizontal and vertical seams with 3 DuPont tyvek 6 After Weather Barrier is installed, refer to the Commercial DuPont Flashing Systems Installation Guidelines to prepare and flash windows and : When installing second layer of Weather Barrier over DuPont tyvek use DuPont recommended fastening schedule using temporary or permanent fastners.
