As you proceed to build a new house, you will have hundreds of issues to manage. Among them, preventing water and air infiltration is the obvious and important one.
If the sheathing isn't suitable, the exterior wall will face water infiltration in many ways. There will also be a chance to form condensed air when the cooler outer air meets the hotter inner air.
This condensed air vapor can then get stuck inside the structure and cause risk to the structure. To fight all this, the easiest solution is to use a good house wrap.
But how do you know which is the best house wrap available out there? Well, we're here to guide you down the lane. Let's get going!

Types of House Wrapping
In its original form, the WRB was built of asphalt-impregnated felt paper, which is the same material used to underlie roof shingles today. WRBs consisting of plastic cloth, such as Tyvek, have recently been referred to as "house wrap" in some contexts.
- It is necessary to use Type 1 asphalt felt (tar paper) in order to meet the ASTM D 226 requirements.
- Grade D construction paper is a kraft paper that has been treated with asphalt and is used under stucco siding.
- Polyethylene or polypropylene fibers are often used in the production of plastic house coverings.
- WRB liquid—As an air barrier, this tar-like liquid is applied with a roller or sprayed on using a spray gun.
- Rigid foam insulation boards—Some rigid foam insulation boards, when properly sealed, can be used as WRBs.
- The use of OSB sheathing panels with certain coatings can be used as WRB sheathing in certain situations.
House Wrap Installation tips and tricks
Always use the fasteners and sealants specified by the manufacturer.
The following are some general fabric-type house wrap recommendations:
- Seams should be sealed with the house wrap manufacturer's appropriate tape.
- Work your way up the course, overlaying lower courses.
- Wrap around doors and windows for a professional look.
- Wrap the fabric around the frame of windows and doors.
- House wrap is used between the top wall plates.
- Prevent chemicals from coming into contact with the fabric.
- Extend the house wrap 2 inches above the footing.
- Install drainage at the bottom of the external siding material if it is recommended.
- Make use of house wrap staples or nails that have been specifically designed for this purpose. Nails should be 1 inch long and spaced 12 to 18 inches apart.
- Overlap horizontal wrap joints by 6 inches.
- Vertical joints should be spaced 6-12 inches apart, depending on the weather.
- Any step-flashed areas will be wrapped in a lap house.
- Install a rain screen to prevent moisture from escaping while installing porous siding.
House Wrap Buying Guide
With so many options available on the market, it is really difficult to choose the best house wrap for people who don't have enough technical knowledge about these products.
So, we came forward and made a comprehensive buying guide that will tell you what to look for when buying a house wrap. Let's see.
Having this feature is crucial for every house wrap; otherwise, it might not keep water out of the walls.
Different testing methods are used to certify any house wrap's water resistance, but two of them are the most common.
One is the Hydrostatic pressure test, where a great amount of pressure is exerted on the wrap through a water column. The column is usually 55cm or greater in size. This testing method is known as AATCC 127.
Another test is known as the water ponding test, where a pond of 1-inch water is made on the wrap, and the result is observed after two hours. This test is designated as CCMC 07102.
Check for any of these ratings while you buy a house wrap to confirm that the wrap is water-resistant and can keep your walls away from water.
Though air resistance is less crucial than water resistance, you should never go with a house wrap with poor air resistance. It will result in airflow across the building envelope. Different methods also test air resistance.
No matter what method is used to test a certain house wrap's air resistance, make sure the wrap does its job perfectly.
Permeability is a term used here to denote the amount of vapor transmission across the wrap over a certain period.
For example, if 400g of vapor can pass through a 1 sq meter area of house wrapper hour, then the vapor permeability of the wrap is 400g/sq meter.
But excess permeability isn't either good for your structures. If the vapor permeability is too high, then the moisture can penetrate the structure from the outside.
So, the vapor permeability should be moderate to balance the inward and outward flow of moisture.
According to various studies, the value of vapor permeability should be between 10 and 20 to be ideal.
Tensile Strength and Tear Resistance
Tensile strength and tear resistance indicate important performance factors that make a house wrap durable and flexible to survive heavy rigors. Choose a house wrap with high tensile strength and tear-resistant to avoid a hassle in the future.
If a house wrap isn't UV resistant, it might lose its integrity over time if exposed to the sun. To make sure your house wrap doesn't degrade over time, choose something that is UV resistant.
Surfactants are usually contaminants like soap and oils that reduce the surface tension of a liquid.
As a result, the wraps become more prone to liquid intrusion, which is never good for your wall systems. So, make sure the house wrap you are buying is surfactant resistant.
