2. The material called Tyvek has gained some popularity in construction. Buildings are wrapped in Tyvek (or a similar product from some other firm). The wrapping is toward the outside of the enclosure, outside of all the building insulation. Write a short (1 page: 500 word) memo that explains what Tyvek is, what purpose it provides, and if the use of Tyvek is consistent with recommendations given in Lstiburek’s article. Please print out your memo.
