EIFS is known as Dryvit, and Sheetrock as gypsum wallboard, to many people and they get upset when you try to clarify it is a tradename.
Some names are only in regions. “Button board” was the slang name for gypsum lath because of the holes. In editing the new plaster manual, Albert Carrillo, my counterpart in Arizona, says it was known as “Little Board” there. Someday we have to have a universal list of obscure names for products and publish the list. I would love to put these in the manual.
Does your region have a “nickname” for a product or system?
