# Dalle Glass: Building Code Definition > How the IBC 2009, IRC 2009 define dalle glass, where the wording differs, and which chapters depend on the term. - Canonical: https://harth.build/resources/glossary/dalle-glass/ - Last updated: 2026-09-07 - Data source: Definitions quoted from the 2009 International Codes as transcribed in this site's building-codes collection, with the source chapter linked for each quotation. Usage counts are computed over the chapters hosted here, one copy per code. The [ICC code library](https://codes.iccsafe.org/codes) publishes the current model text and the [ICC adoption maps](https://www.iccsafe.org/advocacy/code-adoption-maps/) show which edition a jurisdiction has adopted; those sources control. ## Key facts | Fact | Value | | --- | --- | | Defined in | IBC 2009, IRC 2009 (2009 editions transcribed in this corpus) | | Primary source | IBC 2009 Glass and Glazing (model text, not a jurisdiction's adopted text) | | Chapters using the term | 3 (counted across the codes hosted here) | | Wording identical across codes | Yes (compare before citing one code's wording under another) | ## 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. *Content and cited inputs reviewed by [Scott Barrington](https://nz.linkedin.com/in/barrington), Harth founder and architectural technology specialist · Published 2026-09-07 · Updated 2026-09-07.* ## What does this term mean? **Dalle Glass** — IBC 2009, Glass and Glazing: > A decorative composite glazing material made of individual pieces of glass that are embedded in a cast matrix of concrete or epoxy. ![Labeled code-term definition diagram: Dalle Glass: Building Code Definition](https://efwwel0vyt9vy5so.public.blob.vercel-storage.com/images/glossary/dalle-glass/diagram-1344.webp) *How the IBC 2009, IRC 2009 define dalle glass, where the wording differs, and which chapters depend on the term.* ## What must be verified before using this guidance?

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. --- - Continue in Harth (open this topic in the Harth agent): https://app.harth.build/agent?context=%2Fresources%2Fglossary%2Fdalle-glass%2F - View this page in a browser: https://harth.build/resources/glossary/dalle-glass/ - All resources for agents: https://harth.build/llms.txt
