Mortar Break ®
Mortar Break II ®
Mortar Catch ®
The complete Mortar Break II ® System is backed by Advanced Building Products, a leading manufacturer of thru-wall flashings. Mortar deflection devices have gained popularity in recent years, and with good reason. Advanced Building Products was the first flashings manufacturer to see the need to provide a drainage system for all cavity wall construction. Our products have been tested both in the lab and in the field.
Mortar Break II ® is now made from 40% recycled materials and qualifies for L.E.E.D. rating system credits.
Description: Mortar Break II ® is our newest improved mortar deflection device. Mortar Break II ® is to be used in conjunction with standard 2" wide cavity wall construction. Mortar Break II ® is a 1.5" thick, high density, polypropylene geometric design. The slightly narrower profile of Mortar Break II ® allows for a better fit in a 2" cavity and avoids any possibility of mortar bridging the cavity. It is this bridging of mortar, although not continuous, that would allow moisture to travel into the interior wythe of a typical cavity wall.
Polymer Type: High Density Polypropylene.
* BREAKS UP & DEFLECTS MORTAR DROPPINGS AWAY FROM WEEP HOLES.
* ALLOWS MOISTURE IN THE CAVITY TO FLOW DOWN THROUGH THE GEOMATRIX DESIGN AND OUT THROUGH MORTAR MAZE WEEP VENTS.
* EASY AND ECONOMICAL TO INSTALL. (UP TO 50% LABOR SAVINGS OVER CONVENTIONAL METHODS.)
* THE NARROWER DESIGN HELPS AVOID ANY POSSIBLE BRIDGING OF MORTAR ACROSS THE CAVITY.
Basic Use: For use at all flashing locations, such as composite, single wythe and veneer applications (see detail).
Mortar Break II ®, used properly in a 2" or wider cavity, will protect against moisture build-up in a cavity wall.
Composition: Mortar Break II ® is a polymer core geomatrix design woven into a 1.5" thick mesh. The special mesh design catches mortar droppings and suspends them above the weep holes.
Size: Mortar Break II ® is 1.5" (38mm) thick and is supplied in 35' (6.096m) lengths x 10" (254mm) wide.
Installation: Install Mortar Break II ® by placing the strips at all flashing locations. Mechanical attachment is not required.
Short-Form Specification: The mortar deflection device in a 2" or greater cavity wall shall be Mortar Break II ® polymer core geomatrix composed of high density polypropylene geomatrix design woven into a 1.5" thick mesh, as manufactured by Advanced Building Products, Inc., tel: 800-252-2306. The product shall be installed in accordance with the manufacturer's recommendations.
NOTE: Any mortar deflection device is only as good as the flashing with which it is installed. The Brick Institute of America states in its technical note #21: "It is suggested that only superior materials be selected for flashing, as its replacement in the event of failure will be exceedingly expensive."
