Terreal North America strategic market realignment announcement

Terreal North America, in conjunction with its parent company Ludowici, is implementing a strategic market realignment effective in and throughout 2023.  This market refocus will result in Ludowici providing manufacturer direct sales, marketing, and supply support for the complete line of NeXclad small module terra cotta wall cladding systems.  While NeXclad terra cotta cladding systems will continue to be available from Ludowici, Terreal North America will no longer offer large module terra cotta cladding and sunscreen products that are manufactured overseas.  Please visit Ludowici.com to learn more about our made in the USA NeXclad terra cotta cladding systems.

This market refocus aligns with Ludowici’s mission to manufacture sustainable, environmentally friendly, locally sourced, and locally made terra cotta construction materials.  This market approach also brings all terra cotta construction materials produced in our New Lexington, Ohio facility under a single corporate umbrella — Ludowici.
