Flexwrap

DuPont FlexWrap is a moldable flashing material made with Tyvek, an elastic material, a polyolefin film, and a highly adhesive butyl sealant. FlexWrap is engineered to address the issues of flashing the vulnerable bottom corners at the window sill where damage is most likely to occur. FlexWrap is wrapped into the sill rough opening before the window is installed, making one step, seamless protection possible.
