brick terminology brick terminology PSUengineer1 (Structural) (OP) 2 Feb 18 20:32 Have you seen this type of brick before (see attached)? What is the correct terminology? It is on a house chimney. House built circa early 1900s. Thanks, http://files.engineering.com/getfile.aspx?folder=90a8d356-f8e9-4942-aae4-76 RE: brick terminology dhengr (Structural) 2 Feb 18 21:11 PSUengineer1: It looks like a special sized brick. It appears to have about the right proportions, height to width, but it is longer than normal, about (21" minus a head joint)/2. It looks like it might have been made for chimney building and to allow the use of a 12" clay tile liner. Is there a clay tile liner? What are the actual dimensions of the bricks and what are they made of? Your photo really doesn’t show that very well, and the mortar joints tend to blend right in with the brick material.

Nominal length of 8" and a nominal thickness of 4". A guess would be 2-1/4" high since that is a common height for masonry veneers.

Not split block if early 1900’s.
