Learn about Hyload’s masonry flashing systems

Through-Wall Masonry Flashing Systems

Backed by over 25 years of proven performance, Hyload Through-Wall Masonry Flashing was the first-ever high-performance flexible flashing membrane system, originating in the United Kingdom. Since its introduction, our masonry flashing has maintained the position as market leader in the U.K. and is now manufactured in the U.S. by Hyload, Inc. in Wadsworth, Ohio.

The extensive market research and proven performance make our flashing invaluable for today’s construction. The user-friendly system not only provides the specifier with a quality-assured design, but ease of application for the mason as well.

Hyload Flashing Membrane can be used in all wall construction flashing applications: commercial, industrial and residential. Flashing membrane is sealed to the Cloaks by using Hyload Flashing Adhesive. The flashing membrane is secured to the backup wall by either tucking into a CMU joint, or by use of a termination bar. The Brick Institute Association and Hyload recommend that flashing be extended through the wall 1/4″ to form a drip.



The Hyload Masonry Flashing Advantage

  • Three high-performance membranes
  • Three-dimensional preformed shapes or cloaks
  • Sealant compatibility with urethanes and silicones
  • Four membrane colors
  • UV stable

The architectural design and the method in which you physically incorporate our flashing membrane into a building can vary.

To support today’s construction needs, Hyload produces three different types of membranes for use in different applications:
