Brick Bonds

 Starting off the terms sustainable technology tasks with a refresher on brick bonds.  Below are 5 examples of bonds found around the campus and surrounding area. The first being the Common or American bond. Which is a variation of running bond, broken up with courses of full-length headers at regular intervals. In addition to pattern, the headers provide structural bonding. These header courses are typically placed at every fifth, sixth or seventh course. 

Flemish bonds are where each course of brick alternates between stretchers and headers. With the headers in alternate courses centred over the stretchers in the intervening courses.  Flemish bond may be varied by increasing the number of stretchers between headers in each course. When there are three stretchers alternating with a header it is known as a " Flemish garden wall" bond. (Shown on the poster) If there are two stretchers between headers, it is designated as "double stretcher garden wall" bond. 

An English bond is formed of alternate courses of headers and stretchers. The headers are centered on the stretchers and joints between stretchers in all courses are aligned vertically. 

Finally, the Running bond, is the simplest of the core pattern bonds. Consisting fully of stretchers, Running bond is used predominately in cavity wall construction and veneered walls of brick, and often in facing tile walls where the bonding may be accomplished by extra width stretcher tile.
