11. DuPont™ Tyvek® Water-Resistive and Air Barriers Installation Guidelines

Use of Temporary Fastening Methods
Fastener selection and fastening schedule isa function of holding power during
exposure and durability while in service. DuPont” Tyvek® Water Resistive and Air
Bariers nstalation Guidelines require the use of cap fasteners (na, staple and screw)
or 1° crown stapes as the means for permanently attaching DuPont“ Tyvek® WRBS. In
addition to fastener selection, DuPont require a permanent fastener schedule
between 6to 18 inches, anchored o the studs. These fasteners and schedule are
considered à permanent means of attachment and provide substantial holding power
during exposure. Cap fasteners provide additional protection against moisture and air
infitration a the fastener location, especialy when the cladding is in intimate contact
with the waterresistiv barrier and there is minimal drainage. These fastening
‘guidelines minimize the number of penetrations while maintaining a balance of product
durability during exposure, Sheathing other than structural OSB and plywood should
not be relied on as the fastening base. This includes, but isnot limited to, foam,
fiberboard, and gypsum sheathing materials.

Use of recommended permanent fasteners at reduced schedules, other mechanical
fasteners such as smaller staples (slap staples) and adhesives are considered temporary
fastening methods because they do not have substantial holding power and may not
provide adequate durability while in service, Temporary fasteners should not be relied
upon to permanently attach DuPont” Tyvek® WRB. Because these fasteners have
limited holding power, they are not supported by DuPont as the primary means of
attachment.

‘Temporary fastening methods can be used ifthe following guidelines are followed

+ Temporary fastening methods shall only be used to tack the DuPont” Tyvek® WRB.
in place when a permanent fastener is installed immediately after the temporary
fasteners are installed. In this case, permanent fasteners include cladding fasteners
such as brick ties, lath fasteners for traditional stucco, external foam board
fasteners, or siding installed with nails. Cladding shall be installed according to
applicable building codes and industry standards.

Copyright ©2012. Font de Nemours nd Company ARI Reserved Re. 2/12

+ When using adhesives, vertical strips spaced approximately every 24 to 36 inches or
along every other stud line are acceptable. Vertical strips may be applied to the outer
face of the sheathing or directly to the studs for open stud construction. When using
adhesives, care must be taken to avoid excessive surface coverage as this may
impact the vapor permeability in that area. Adhesives should be evaluated for
‘compatibility with DuPont” Tywek* WRBs.

+ When using temporary mechanical fasteners, they should be used minimally to tack
the DuPont” Tyvek® WRB in place. Smal staple fasteners are acceptable with OSB,
plywood and exterior gypsum sheathing only. Small staple fasteners should not be
used with fiberboard or foam sheathing. Temporary fastener schedule should not
‘exceed four 4) fasteners per square yard. Tape all tears and localized damage. For
larger holes (greater than 1") follow instructions on page 7 of this guide.

Selection and use of temporary fastening methods is an option dependent on building

schedule, cladding type and local building practices.

NOTE: These Temporary Fastening Guidelines are subject to change based on new.
technology or testing information and may be superseded at any time. It is always
important to follow the latest guidelines which may be found on

Key Installation Requirements for Wraps

Continuity

It is important to maintain the continuity of the WRB throughout the building envelope.
‘The entire wall surface shall be wrapped. including unconditioned spaces. Special
attention should be given to ensure a proper 6” overlap at all terminations, seams,
Penetrations, and transitions to maintain a continuous downward drainage plane and
WRB. Instaling the DuPont” Tyvek® WRB as an air barrier is the preferred installation
method, but when the DuPont“ Tyvek® WRB is being installed as a water-esistve
barrier only (residentiallow-ise), then skip-taping terminations and untaped horizontal
seams is allowed. All vertical seams must be taped for both air barier and water-

Seal the DuPont“ Tyvek® Products around al penetrations (electrical, HVAC and
plumbing, etc.) with the appropriate DuPont” Flashing Systems product, DuPont”
Tyvek® Tape, DuPont” Residential Sealant, DuPont” Commercial Sealant, or
recommended sealant. Products that have flanges should be integrated into the
DuPont” Tyvek® WRB. DuPont” StraightFlash”, DuPont” Flashing Tape or DuPont
recommended alternate patches should be applied behind fastening plates (brick tie
base plates, metal fastening clips, metal channels, etc) when building envelope design
requirements exceed ASTM E1677, 65 mph equivalent structural load and 15 mph
equivalent wind-driven rain water infiltration resistance. Please contact 1-800-44-Tyvek
for recommended sealants and recommended alternate patches behind fastening plates.

Overlap
Ensure proper shingling with a 6" minimum overlap of the WRB components from the
bottom to the top of the wall to help faclitate proper drainage.

Fasteners
Use DuPont fasteners or DuPont recommended alternates per the fastening schedule
included in this installation guideline, Temporary fasteners should not be relied upon to
permanently attach DuPont” Tyvek® WRBs due to the limited holding power of these
fastening methods, and will not be in compliance with the DuPont” Tyvek® Water-
Resistive and Air Barriers Installation Guidelines. If temporary fasteners are used,
permanent fastening must be applied as soon as practically possible in order to maintain
the integrity and performance of the DuPont” Tyvek® WRB. Refer to the DuPont”
Tywek® Weather Barrier Commercial Installation Guidelines, for more complete fastening
information. Examples of recommended permanent fasteners include:
+ DuPont“ Tvek® Wrap Cap nails (for wood frame construction)
+ DuPont“ Twek® Wrap Cap Staples for Stinger” (for wood frame construction)
+ 1.0 inch minimum crown staples for residentialiow rise construction (except
when installing DuPont” Tyvek® WRB over foam sheathing)
+ 1 plastic cap staple with leg length sufficient to achieve $/8”penetration into
