Expert Verdict — Reviewed by the SuperArbor Pro Desk
Blueskin TWF is a dependable choice for base-of-wall, sill and head thru-wall flashing because the rubberized asphalt grips prepared masonry and concrete and self-seals fastener penetrations. Plan laps carefully and detail corners with appropriate pieces to keep the flashing continuous. In cold weather take advantage of its low-temperature flexibility but verify substrate condition and priming before application.
Follow Henry's substrate preparation, priming and application temperature requirements, and handle cuts carefully as the membrane edges can be sharp to trim.
Order Henry Blueskin TWF 12 in. x 75 ft. for a self-adhered thru-wall flashing you can trust.
