One of the biggest, most common issues surrounding any house wrap is its durability. In the event of a delay or break in the project, your house wrap may need to be redone before siding can be installed.
While most house wraps are opaque, which can present issues with finding the framing for siding installation after the wrap has been put on. This, in turn, can lead to issues with the siding installation and moisture penetration down the road. Because Barricade is semi-transparent, you can easily find the framing after installation.
This makes the siding installation not only more efficient and faster, but it also helps reduce potential issues after installation has been completed. Barricade is also a very lightweight product, which means that it can go up easily as well. And, just like air gets in, so can water and moisture. DuPont Tyvek HomeWrap gives you the added benefit of helping to protect your walls from water and moisture. Tyvek DrainVent is a patent-pending three-dimensional honeycomb-textured drainage mat with attached heavy-duty filter fabric that creates a space for water drainage and air movement behind cladding.
It can be installed behind exterior claddings such as stucco, stone veneer, brick, wood and fiber cement lap siding, or metal panel systems. Typically this space is 1"-2" and will act as a drainage plane if incidental moisture were to penetrate the brick.
Tyvek CommercialWrap should be covered within days 9 months. Follow the DuPont Tyvek installation instructions included with the home weatherization product. Using a vapor barrier depends on how the rest of the wall system is built and the climate the wall is in. If the majority of the year is spent heating the home where the inside temperature is greater than the outside, it is generally good to use a vapor retarder behind the interior drywall. In hot humid climates, vapor barriers should not be used.
DuPont Tyvek HomeWrap can be used either over or under sheathing. When DuPont Tyvek HomeWrap is used under sheathing, it functions only as an air barrier and does not protect the sheathing as a secondary water barrier. DuPont Tyvek HomeWrap has been used directly over studs where there is no sheathing, although the use of sheathing is a highly recommended building practice.
Tyvek DrainWrap offers the unique combination of a drainage system and a weather-resistant barrier in a single product and promotes outstanding bulk water drainage behind siding such as primed cedar by channeling moisture safely to the outside.
However, DuPont Tyvek StuccoWrap and Tyvek DrainWrap has a specially engineered surface that should be placed with the grooves in a vertical direction. DuPont Tyvek HomeWrap can be installed using a variety of fasteners, which will depend on the application.
If you are applying DuPont Tyvek HomeWrap to wood, insulated sheathing board or exterior gypsum board, then use:. DuPont Tyvek CommercialWrap is a building wrap for use behind stucco, stone, marble, metal panels, brick, granite and EIFS on large commercial applications.
It establishes a highly efficient building envelope system by controlling air leakage, preventing water infiltration and allowing moisture to escape. For a typical two-story, square foot house, the general rule of thumb is two rolls of DuPont Tyvek size 9' x ' should be adequate to wrap the house. However, this estimate may vary slightly depending on the house elevation. Many other wraps are perforated, which means in order for them to breathe, the manufacturer has punched holes in them, resulting in a reduction of air and water holdout effectiveness.

Building codes and material manufacturers recommend adjustments when installing Tyvek under certain materials, for maximum air and water barrier effectiveness.
Consider these tips if you plan to use these materials over the Tyvek, as they affect your construction plans or the amount of Tyvek you need to buy: Stucco and stone veneer do best with two layers of Tyvek. Brick and foam sheathing should have an air space between it and the Tyvek.
Other materials may be installed as usual, although measures that reduce moisture in contact with the Tyvek are always recommended. Purchase the correct Tyvek product. Tyvek HomeWrap is suitable for most residential houses. Tyvek ThermaWrap will also help maintain desirable indoor temperatures, while Tyvek DrainWrap includes vertical grooves for increased drainage when high moisture is expected. If you are constructing a commercial building, or a building more than four stories tall, consult an experienced construction expert or DuPont representative for information on more specialized products, such as Tyvek Fluid or high-performance Tyvek.
Purchasing Tyvek tape as well is recommended to help seal your wall more effectively, as described below. You may be able to purchase your Tyvek with stud marks printed on the surface at a specified width, which will make it easier to line up with your wall.
Position the Tyvek. Begin by placing an edge of Tyvek at one end of the wall, leaving a 6—12 inch 15—30 cm overlap over the corner. If stud marks are printed on your Tyvek product, line them up with the first stud of your wall. The first roll should be plumb with the bottom edge of the wall.
If the wall has not yet been raised, let the Tyvek overhang the bottom edge of the wall and fasten it there with Tyvek tape or sealant. Unroll and attach the Tyvek. Unroll so the Tyvek is taut, but not so much that it gets stretch marks or tears when fastened.
Have a second person secure the Tyvek with a fastener every 6—18 inches cm , over the wall studs. Once the whole roll is attached, use cladding fasteners to attach it permanently.
Over wood, gypsum board, and most other wall materials, use large head or washer head nails. Unless installing over foam sheathing, you may use staples with at least 1 in. Cover doors and windows. Ideally, install Tyvek before installing the doors, windows, or window flashing.
However, no matter what stage of construction these areas have reached, you may cover them completely with the Tyvek while first installing. You will make adjustments to these areas once the wall is covered as described below.
Overlap additional rolls of Tyvek to cover the whole wall.
