Tyvek is a synthetic product made of high-density polyethylene fibers. It is often used as a building wrap to protect the exterior of a structure from water and air infiltration. Tyvek has also been used as a vapor barrier in some applications, but its effectiveness as a vapor barrier has been debated.

Tyvek is a material that is often used as a vapor barrier. It is made of high-density polyethylene fibers and is resistant to water, mold, and mildew. While it can be an effective vapor barrier, it is not 100% effective and should not be relied upon as the sole means of preventing moisture damage.

What's the difference between Tyvek and other vapor barriers?

Is Tyvek Vapor Permeable

If you’ve ever seen a construction site, you’ve probably seen Tyvek. It’s that white, paper-like material that is often used as a temporary covering for walls and doors. You may have also seen it used as packaging material or envelopes.

What you may not know is that Tyvek is actually a vapor permeable material. This means that it allows water vapor to pass through it, which can be helpful in preventing condensation and mold growth. One of the benefits of using Tyvek as a vapor barrier is that it doesn’t require any special installation methods like taping or caulking.

It can simply be laid over the surface to be protected and will do its job without any fuss. Another benefit of using Tyvek is that it’s very strong and durable. It won’t tear easily and can withstand a fair amount of abuse.

This makes it ideal for use in high traffic areas or in situations where there is potential for damage (like on construction sites). Overall, Tyvek is an excellent choice for a vapor barrier material. It’s easy to use, effective, and long lasting – all qualities that are important when choosing a product to protect your home or business from moisture damage.

Do I Need a Vapor Barrier If I Have House Wrap?

If you’re like most homeowners, you want your home to be as energy efficient as possible. One way to do this is to make sure your home is well insulated. Another way is to install a vapor barrier.

But do you really need a vapor barrier if you have house wrap? The answer isn’t always clear cut, but in general, the answer is yes – it’s a good idea to install a vapor barrier in addition to house wrap. Here’s why:

1. House wrap alone won’t stop all air leaks. A properly installed vapor barrier will help seal up any small gaps or cracks that might exist around windows, doors, and other openings. This will make your home more comfortable and reduce your energy bills.

2. House wrap does not provide an effective moisture barrier. If you live in a humid climate or if your home tends to be damp, a vapor barrier will help keep mold and mildew at bay by preventing moisture from seeping into your walls and ceilings. 3. A vapor barrier can extend the life of your insulation.

By keeping out moisture and reducing air leaks, a vapor barrier helps protect insulation from degradation caused by these elements.

Does Tyvek Let Moisture Through?

By controlling the moisture and condensation inside your home, you can help to prevent mold and mildew from growing.

What Can Be Used As a Vapor Barrier?

There are many different materials that can be used as a vapor barrier. The most common material is polyethylene, which is a type of plastic. Polyethylene is available in sheets or rolls and can be installed over the top of insulation or directly against the wall surface.

Other materials that can be used as a vapor barrier include foil-faced kraft paper, aluminum foil, and special paints.


Tyvek is a material made of high-density polyethylene fibers that are spunbonded together to create a fabric. This fabric is then used to make products like Tyvek housewrap, which is used as a vapor barrier in construction. While Tyvek is an effective vapor barrier, it is not perfect.

Tyvek can tear easily and does not provide a complete seal against air and water. In addition, Tyvek is not UV resistant and will degrade over time if exposed to sunlight.
