About TerraGlas® Terra Cotta

TerraGlas® is a molded architectural terra cotta composite with fiberglass reinforcing. TerraGlas® offers the traditional architectural terra cotta look and feel. It is available in limitless molded shapes to exactly replicate historical terra cotta elements. TerraGlas® terra cotta is available in both flat or glazed colors that can be carefully matched to existing terra cotta for restoration, replacement or re-creation. Made from natural terra cotta, aggregates, and minerals and reinforced with glass fibers, TerraGlas® provides the look, shape, feel and appearance of historic terra cotta, but without the weight and brittleness. The reduced weight reduces the load on the historic structure and the installation costs are significantly less.

Replication and Restoration

TerraGlas® offers the ability to closely match existing architectural terra cotta in color, shade and texture. TerraGlas®.does not have the shrinkage issues that plague traditional architectural terra cotta. This allows a virtually identical match of historic terra cotta architectural details to be created. For restoration and replacement, in order to achieve a custom color and finish match, we require a small physical sample of the desired color and texture.

TerraGlas® is a pre-finished material, and we strongly recommend that it be installed by skilled restoration contractors, experienced stone masons or finish carpenters. The material is cut and installed using diamond saws or angle grinders. In some cases TerraGlas® can assist with installation or recommend a quality contractor.

Basic Uses and Limitations of TerraGlas® Architectural Terra Cotta
Historic Preservation, Restoration, Renovation of Historic Structures

The renovation and preservation of older buildings can be challenging. Terra Cotta was widely used from the 1860's to the 1930's on many significant and beautiful buildings. In some cases the terra cotta is now damaged, failing or missing due to weather, rust of anchors, glaze failures and other problems. TerraGlas® Terra Cotta offers an accepted and approved method of making cost effective and timely replacement of the old failing terra cotta elements with an in kind material. By combining the durability of terra cotta with the strength of glass fiber reinforcing, TerraGlas® Terra cotta offers the look, feel and weathering of terra cotta in a lighter weight, more impact resistant material.


Often the original terra cotta elements are missing completely and all that remain are old drawings or photographs. We can help with the restoration and replacement of terra cotta even if there are no existing pieces to take molds from.

New Construction

Often new construction benefits from the use of architectural details in Terra cotta. We can provide a stronger, lighter and more economical alternative to traditional terra cotta.
