INSTALLATION INSTRUCTIONS

1. Position the rainscreen: Install Fire-Rated Sure Cavity® over the water-resistive barrier with the mortar-blocking fabric facing the installer.
2. Back-wrap the fabric: Use the 4″ fabric skirt to create a bug screen on the lowest course. Overlap the fabric shingle fashion on subsequent courses.
3. Align the material: Butt the corrugated material at seams; overlapping is unnecessary. Channel alignment is also not required.
4. Wrap corners: Extend the rainscreen around corners to the nearest structural member for complete coverage.
5. Fasten securely: Attach every 24″ on-center using a hammer stapler over nailable surfaces. For masonry walls, use dime-sized dabs of adhesive to hold it in place. Lath or veneer will permanently sandwich the rainscreen.
