What is Tyvek?

Tyvek is a brand of synthetic flash-spun high-density polyethylene fibers manufactured by DuPont Chemicals. Since its invention in 1955, Tyvek has been used in a huge number of applications in the construction industry, mainly to protect buildings from rain and dampness while also allowing them to breathe. Another common use for Tyvek is in personal protective equipment (PPE) such as coveralls and HAZMAT suits used for asbestos and radiation work.

Which Type of Tyvek Contains PFAS?

According to the U.S. EPA, uncoated Tyvek does not contain PFAS, while coated Tyvek does contain PFAS. Coated Tyvek has a coating on it (typically clay), so it’s “sealed.” Uncoated Tyvek does not have this coating and is thus more porous.

Is Tyvek Hazardous?

In addition to potentially containing toxic PFAS, Tyvek PPE can generate a considerable amount of static electricity during use. In situations where static dissipation may occur, users should evaluate the performance of their entire ensemble, including outer garments, inner garments, footwear, and other PPE.

Is Tyvek Used for Sterilization?

Tyvek is made of 100% high-density polyethylene (HDPE), which is extremely stable when exposed to sterilant gases and high-energy sterilization processes. Additionally, Tyvek is engineered to enable sterilant gases and steam to penetrate and escape quickly.

What is Better Than Tyvek?

Due to the potential PFAS contamination from Tyvek, a better material to use to protect buildings from air and moisture resistance is Barricade Building Wrap. This product is engineered with high-performance features offering faster, easier, and more reliable installs than Tyvek.

Is Building Wrap Necessary?

While it may seem like an unnecessary and time-consuming addition to your home, house wrap is necessary for every home, no matter the climate. This is because house wrap provides an effective moisture barrier for the home.

What Happens if You Don’t Wrap a House?

While you aren’t required to install house wrap under vinyl siding, it can protect your home from moisture and mold damage. Mold can easily grow under siding on homes that don’t have a house wrap. Most house wrap is very cheap, costing around $0.40-$0.60 per square foot and less than $1,000 for most homes.
