Claustra bond is a masonry bond in which bricks are deliberately laid with open gaps between them, creating a regular pattern of openings in the wall. It combines the structural function of brickwork with light transmission, ventilation and decoration.
How is it made?
In claustra bond, bricks are placed in specific ways to create openings:
- On edge — bricks are placed vertically or diagonally
- Gaps — bricks are laid with deliberate spaces between them
- Patterns — variations in placement create diamond, square or diagonal openings
- Jointing — only the contact points are jointed
Application
Claustra bond is popular for:
- Garden walls — decorative walls that allow wind through while providing privacy
- Boundary walls — open yet screening
- Ventilation grilles — in crawl spaces and agricultural buildings
- Facade accents — decorative bands or panels in an otherwise closed facade
- Pergola walls — as a light partition in outdoor spaces
Structural considerations
- Stability — a claustra wall is weaker than a solid wall; limit the height or add piers
- Frost resistance — use frost-proof bricks for outdoor applications
- Mortar choice — use mortar that bonds well to small contact areas
