E-Flange Control Joint

ClarkDietrich announces the addition of its E-Flange Control Joint to its vinyl product line. The patent-pending E-Flange features a unique raised flange design that provides 80% more stucco embedment than standard “flat flange” profiles.


The larger triangular perforations in ClarkDietrich E-Flange allow more stucco mix to flow through the flange, providing more thorough and consistent embedment. In addition, the unique E-Flange shape allows for quick tying of lath and other accessories, making for easier installation.


Specially designed connector clips are provided with the E-Flange Control Joint for easier alignment and a base for sealants. Factory fabricated joint intersections are also available in cross, tee and right-angle configurations to be used as needed.


The ClarkDietrich E-Flange Control Joint complies with all associated ASTM and code standards for exterior vinyl materials per ASTM D1784 and ASTM C-1063, Table 1. The product also meets the requirements for full embedment of the assembly per ASTM C1861 & C1063, and assist in accomplishing the ASTM provision for tying the control joint to the lath through its rib sections in the flange area.


A full line of E-Flange casing beads will be available in early 2019.
