GFRC CSI SPECIFICATION SUMMARY (SECTION 03455)

MANUFACTURERS:

• Willis Construction Co.

• Stromberg Architectural Products

• GFRC Cladding

• TerraGlas

Other Materials From “Related Sections”:

• Architectural Precast Concrete - common for similar uses for cladding and wall products

• Masonry Veneer - another material like GFRC used primarily for exterior finishes/aesthetics and not for structural reasons

• Granite - another siding material for a different aesthetic than GFRC

• Structural Steel - can be used as the primary structure in which GFRC can attach to

Choices Needed to Make and Questions:

• In order to add color to the GFRC during mixing, I first must decide what color fits with the aesthetic of the building and environment, which also brings the question of how to find a color that not only is harmless to people or the product, but also fits within the context and concept of the building?

• It is more standard providing connection from GFRC to concrete or steel, but how do the connections work for attaching to mass timber so the same structural integrity is reached as in steel or concrete?

• Is it possible to use a light wood frame stud system for fabrication and erection rather than the specified steel stud welded frame to offer a more sustainable and low energy solution?
