A claustra, also known as a Brazilian bond, is characterized by openings in the masonry. These are created by laying the bricks only with their ends on the underlying bricks. This results in a translucent effect in the facade, creating a stunning aesthetic feature.
Advantages of claustras:
Aesthetic appeal
Natural light with privacy
Adds extra distinction to the facade
Gives the facade the effect of lacework
Disadvantages of claustras:
Limited contact surface results in weaker masonry
Precipitation must not enter the cavity! Seal the cavity so that occasional rainwater can be drained.
Behind the claustra wall, a load-bearing wall is usually not provided; therefore, the anchoring of the facade requires greater attention!
The length-to-height ratio must be carefully considered to ensure stability.
Key considerations:
Adhesive is stronger than mortar and also bonds better.
Keep the contact surface as large as possible.
Fewer openings per surface area.
Limit the height of the openings (over fewer brick layers).
