This will allow you to roll out several feet and still be able to adjust the roll up and down without creating wrinkles. Wrinkles don’t just look sloppy- they can also become traps for water. Taping the horizontal and vertical seans is among the requirements of getting the Tyvek products Labor and Material Residential 10-year limited warranty. Here you should secure the bottom flap and fasten the side flaps to the foundation. To get an optimum reduction in air leakage, use a DuPont StraightFlash, Tyvek Tape, and weatherization sealant to seal wrap at the bottom of the wall. Secure and unroll the Tyvek water-resistive barrier over the wall section.
The proof is in the performance
Water tends to condense on house wrap, much more so than it would if there was just wood sheathing behind the siding. That water will penetrate wood siding and lift off the finish. So it’s more important than ever to prime the back side of wood siding before it’s installed. Years ago, only vertical seams in house wrap required tape, but no longer. Now every seam must be taped, and most manufacturers recommend that a minimum of 1 in.

It’s not only seams that need taping—everything that penetrates a wall needs it too! When starting a new row, don’t fasten the whole vertical length of the wrap right away. Get the roll into position, and attach a few fasteners in the center of the paper.

And by the time it is discovered the damage can be extensive. Cut out around it as closely as you can, then make two angled cuts up and away from the top of the pipe. Tape the flap up to keep it out of the way and then, starting at the bottom, tape the pipe to the wall. For more information on this step, read our story on window installation. This method will meet the requirements of most window manufacturers, and best of all, the inspector will be happy.

Another problem with fine wire staples is they frequently pull-through the WRB on windy days leaving holes that often don’t get patched. Always begin at the bottom of your structure to enable proper shingling throughout the whole installation. Proper shingling is necessary for restricting water from entering the wall system and providing for water shedding. You should install vinyl siding directly over Tyvek WRB. You should install vinyl siding as per the applicable codes, industry standards, and manufacturer’s instructions.
Ensure that the stud marks that have been printed on the roll and the Tyvek lineup are plumb. If the hole is larger than 1″, you might have to cut a piece of water-resistive barrier to cover it. Begin flashing or taping at the shingling upper tape, the bottom of penetrations, and over the bottom tape.

Engineered for superior building envelope performance
Leave enough lap to guarantee at least a 6″ overlap of the water-resistive barrier for all sides, except for the top wall. The bottom edge of the roll must extend over the sill plate interface for at least 2″. It would help if you sealed the wrap at the bottom of the wall using sealant to prevent air leakage. A rigid foam board will offer enhanced structural support to the Tyvek layer when installing it over the Tyvek WRB as an intervening layer. However, if you install a rigid foam board within 24 hours of the Tyvek layer, it may reduce the number of fasteners you require for the attachment of the Tyvek WRB.
Prime Wood Siding Before Installing House Wrap
It prevents drafts and heat loss in colder climates while keeping the building cooler in hot weather. Unlike perforated wraps, DuPont™ Tyvek® weather barriers are made of a continuous, nonwoven, non-perforated sheet. The sheet is created by spinning extremely fine, continuous, high-density polyethylene (HDPE) fibers that are not fused together, to form a strong, uniform web.

Of the tape be sealed to each side of the seam—that’s hard to accomplish using 2-in. If not, like practically everything else, it’s available online. Yes, you can hand-nail capped fasteners when installing house wrap, but it’ll take you forever.
Tyvek barriers are designed from tough materials that are difficult to tear. While beginning a wall section, you should fold and secure the starting side flap over the vertical stud side. The bottom flap should overhang just enough for the wall to overlap the sill plate when tilted upright.
DuPont™ Tyvek® Housewrap offers durable protection from moisture for walls and is also breathable to reduce condensation. Siding jobs do leak so when the water-resistive barrier leaks, water can get into the wall and lead to mold and rot. Often the leak can go on for many years inside the wall before anyone notices.
The superior vapor permeability of Tyvek® HomeWrap® correlates to decreased wall cavity drying times, and a reduced potential for mold and wood damage. A windy day can make house wrap installation a frustrating experience at best. So cut full rolls down to more manageable sizes with a circular saw.
Forest Product Laboratory and the “Western Red Cedar Lumber Association,” you should prime wood on all six sides before installation. The same testing also revealed a considerable difference in comparative moisture vapor transmission. Tyvek®HomeWrap® exhibited nearly four times the vapor permeability of perforated house wrap, which can only allow vapor to pass through punched holes.
As per the 2006 International Residential Code, there must be at least a 1″ airspace splitting the water-resistive barrier from the brick. There should also be at least a 2″ airspace ahead of steel stud construction and 1″ airspace before wood stud construction. Water vapor can easily pass through Tyvek barriers, but water in liquid form can’t. It’s as a result of these properties that Tyvek is employed in different applications. Tyvek allows the building to breathe without letting water through it.
Start at the bottom of the wall and work your way up, nailing or stapling the wrap every 12 to 16 inches along the studs or sheathing. Tyvek is a brand name often used to refer to water-resistant barriers (WRB), also known as house wrap. The International Building Code (IBC) requires a water-resistant barrier to be installed behind the exterior cladding. Water-resistant plastic barrier materials are not exclusive to Tyvek, and similar products are manufactured under dozens of trade names.
When it comes to securing house wrap, the recommended approach is to use either plastic cap nails or plastic cap staples. Both options are effective in fastening the building wrap securely in place. Thus, it’s essential to consult the local building codes and consider the specific requirements of the project before deciding whether to use nails or staples for house wrap installation. To securely fasten Tyvek house wrap, it is recommended to use nails or staples specifically designed for house wrap, such as STINGER Fasteners and DuPont Tyvek Cap Fasteners. These fasteners are specifically designed to secure house wrap effectively.
