Tyvek is a nonwoven product consisting of spun bond olefin fiber.It was first discovered in 1955 by a researcher for the DuPont textile company working in an experimental lab, who noticed a type of white fluff coming out of a pipe. [2]
A building wrapped with Tyvek-brand housewrap during construction. Housewrap (or house wrap), also known by the genericized trademark homewrap (or home wrap), generally denotes a modern synthetic material used to protect buildings.

Where museums cannot completely reduce their use of materials or replace materials with sustainable alternatives, material re-use is an option for extending the useful lifetime of conservation materials. Durable materials used in conservation such as Tyvek or Mylar may be washed and re-used where appropriate. Polyethylene foam may be blended ...
