Fire-Rated Sure Cavity Highlights

No wall is waterproof. Today’s "tighter" buildings increase the risk of moisture and mold problems that rainscreen systems greatly reduce by enabling moisture to swiftly exit the building envelope. Municipalities are increasingly requiring fire-rated walls for multi-story residential structures. Fire-rated rainscreens are inexpensive insurance to mitigate the risk of wall failure and meet stringent building codes.

Fire-Rated Sure Cavity Installation

  • Install Fire-Rated Sure Cavity™ rainscreen outboard of water resistive barrier. Mortar-blocking fabric faces installer.
  • Back-wrap 4" fabric skirt to create bug screen on the lowest course. 4" fabric skirt will lap shingle fashion in subsequent courses.
  • Corrugated material to be butted at seams. Do not overlap corrugated material. It is not necessary to align channels.
  • Wrap rainscreen around corners and extend to nearest structural member.
  • Fasten every 24" on-center with a hammer stapler over nailable surfaces. On masonry backup walls use dime-size dabs of adhesive to hold in place. Installing lath or veneer will ultimately sandwich rainscreen in place.
