Direct answer

Dalle glass is a defined term in the International Building Code (IBC) 2009, in Glass and Glazing. The code's own words are: “A decorative composite glazing material made of individual pieces of glass that are embedded in a cast matrix of concrete or epoxy.” The IRC 2009 carries the same definition word for word, so the term means the same thing in each. The term is used in 3 chapters of this corpus, most often in Definitions (IRC 2009), Definitions (IBC 2009), Glass and Glazing (IBC 2009). These pages transcribe the 2009 model text; verify the definition against the edition and amendments your authority having jurisdiction has adopted. Record the jurisdiction, the adopted edition, the application date and any local amendment that rewrites the definition before you use it on a live project, because a term redefined by amendment changes every requirement that depends on it.

Frequently asked questions

What is the code definition of dalle glass?

The International Building Code (IBC) 2009 defines it in Glass and Glazing as: “A decorative composite glazing material made of individual pieces of glass that are embedded in a cast matrix of concrete or epoxy.” The 2009 model text is reproduced here; the definition that binds your project is the one in the edition your jurisdiction has adopted, as amended locally.

Which parts of the code depend on dalle glass?

In this corpus the term is used across 3 chapters, led by Definitions in the IRC 2009. Those are the sections whose scope moves if the definition is amended locally, so read them together with Chapter 2 rather than on their own.

What are the requirements for tempered glass in the International Building Code?

Building is a separate defined term. The IBC 2009 defines it as: “Any structure used or intended for supporting or sheltering any use or occupancy.” That is not the same as dalle glass, which the IBC 2009 defines as “A decorative composite glazing material made of individual pieces of glass that are embedded in a cast matrix of concrete or epoxy.” — read both before applying either, and confirm the wording in the edition your jurisdiction has adopted.
