Brick
Solid brickwork is made of two or more layers of bricks with the units running horizontally (called stretcher bricks) bound together with bricks running transverse to the wall (called "header" bricks). Each row of bricks is known as a course. The pattern of headers and stretchers employed gives rise to different bonds such as the common bond (with every sixth course composed of headers), the English bond, and the Flemish bond (with alternating stretcher and header bricks present on every course). Bonds can differ in strength and in insulating ability. Vertically staggered bonds tend to be somewhat stronger and less prone to major cracking than a non-staggered bond.

Famous quotes containing the word brick:

“They dropped separately after the celebration,
handpicked,
one after the other like artichoke leaves.
After that I walked to my car awkwardly
over the painful bare remains on the brick sidewalk....”

“Follow the yellow brick road.”
