This program provides an in-depth look at terra cotta as an architectural cladding material, its manufacturing, overview of its performance, and methods of repair.


Architectural terra cotta was a prominent cladding material in the United States from the late 19th century to the 1950s. During that time period, it was manufactured and used as a durable and decorative material. Terra cotta is a high-performance material. When failure does occur, it’s generally associated with the secondary material used in the assembly, lack of maintenance, or improper installation.

The Terra Cotta Installation and Repair Program teaches craftworkers about mechanisms behind deterioration and proper installation/repair methods through classroom and hands-on exercises.

The program was developed by IMI and IMTEF, together with key design partners at WJE and manufacturing partners Boston Valley Terra Cotta and Gladding McBean Terra Cotta.
