Preservation Technology — The Three G’s: GFRG, GFR

Description

Join the California Preservation Foundation for Part I of a multi-program themed series on Preservation Technology.

Part I will focus on the manufacture/assembly, composition, use, and restoration of three key ‘G’s’ of preservation materials: Glass Fiber Reinforced Gypsum (GFRG), Glass Fiber Reinforced Polymer (GFRP), and Glass Fiber Reinforced Concrete (GFRC).

The program will include an introduction to the materials, how they are used in historic preservation, and how they meet material considerations of the Secretary of the Interior Standards; when and why they are used in both original construction and historic preservation projects; the chemistry, manufacture, and testing of each material; and how they age. Case studies will highlight real-world examples of using each material, as well as the positives and challenges associated with them.

This program will be part one of a three-program series with a focus on preservation technology.
