DuPont Tyvek HomeWrap is a nonwoven, nonperforated sheet made by spinning extremely fine continuous high-density polyethylene (HDPE) fibers that are fused together to form a strong uniform web

DuPont Tyvek is a unique brand and the only product manufactured this way

This tough, durable, and unique structure is not susceptible to the compromises of a perforated material

The fibrous structure is engineered to create millions of extremely small pores that resist bulk water and air penetration while allowing moisture vapor to pass through

DuPont Tyvek Home Wrap achieves the balance of weather resistance and vapor permeability
