Values for
Solid extruded clay/shale brick units (BIA 1993 manufacturer survey, TN 3A 2024); face brick of 130 lb/ft3 for thermal properties (BIA TN 4, from ASHRAE 2013); CTE is the TMS Code value for clay/shale masonry
Every value links to the document that states it. "Not sourced" means no citable source states it (or only a specification minimum); figures computed from it are left out too.
