Keep reading to learn about house wraps and nine of the other top wrap brands available today. Drainage is an effective method to lessen moisture infiltration to the wall assembly due to rain. A house wrap’s design should provide an integrated gap and a drainage plane so to resist bulk water. 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.
UV Stability
The installation process typically takes longer, beginning with a base coat that starts at the bottom and goes up. After the base coat, the seams and corners of the building are reinforced with polyester joint fabric, then a second coat is applied. It's also worth noting that liquid water-resistive barrier is one of the most expensive options to install. However, it's important to note that house wrap is not completely impermeable or waterproof.
Water Management
This product is essentially a kraft paper with asphalt integrated into the design to increase the water resistance of the material. It's often used under stucco exteriors and has a similar vapor permeability as asphalt felt house wrap. One drawback to using grade D building paper is that it can deteriorate if it remains wet for a prolonged period of time.

Durability parameters include ultraviolet (UV) rating, tensile strength, and cold and surfactant resistance. Fastening requirements for the WRB are not mentioned in the IRC. Figuring that tarpaper installation must be “free from holes and breaks,” it’s important to consider the effect of common installation practices like fine wire hammer-tacker staplers.
The panels comprise oriented strand board (OSB) wood structural sheathing with a Grade-D 60-minute WRB exterior facer of medium density phenolic-impregnated polymer-modified product. The seam sealing tape is a polyolefin sheet, backed with acrylic adhesive. A crucial requirement of a house wrap is to keep water out of the wall assembly. The ICC-ES allows for three water-resistance testing standards; however, plastic wraps are permitted only to use the first two. Inevitably you’ll have to deal with a tear in your beautiful handiwork.

If cost is a primary deciding factor asphalt felt and grade D building paper are affordable, effective ways to protect the home from moisture. House wraps are usually made from woven fabric or a combination of layers that are held together and attached to your home’s exterior. The most common house wraps are made from polyethylene, a durable plastic material resistant to tearing and cracking.
However, if you are installing house wrap on a new building, the wrap typically remains exposed to direct sunlight during construction, which can last for several weeks. If the house wrap is not resistant to UV radiation, it can begin to break down during this period, so it's recommended to invest in a house wrap with built-in UV protection. House wrap is designed to protect the home against rain, sleet, snow, and any other type of moisture that may seep through the exterior siding.
House wrap is designed to be permeable so that moisture can exit the home, instead of getting trapped inside the wall cavity. The permeability of the material depends on the type of house wrap, but can also vary between individual products, so it's important to check the listed permeability of the product before purchase. Permeability is measured in US perms, with one perm equal to one gram of water vapor per hour per square foot per inch of mercury. If you are building a new home or replacing the exterior siding on an existing property, then it's a good idea to consider investing in house wrap. Most house wrap options have a permeability rating between five and 60. Typically, a minimum of five is required by most building codes.
Polyolefin house wrap is light, easy to work with, and has a high level of vapor permeability, water resistance, and tear resistance. However, it is susceptible to the surfactants that can leach out of wet cedar siding, redwood siding, and stucco cement plaster. The primary purpose of house wrap is to prevent water from reaching the wall cavity of the home, so it's necessary to find a product with a high level of water resistance. Barricade® Wrap Plus is a non-perforated, non-woven polyolefin product with a semi-permeable membrane. This type of house wrap is essentially a water resistant liquid that is applied with a roller or sprayer to create a continuous, seam-free coating to protect the home. Vapor permeability (measured in US perms) is the amount of vapor transmission that a house wrap permits over a time period.
