Worked example
A 20 × 8 ft single-brick wall of US modular bricks needs about 1,050 bricks including 5% waste.
How many bricks per square meter?
About 60 UK bricks or 57 US modular bricks for a single-thickness wall with 10 mm joints.
Why double brick?
Double (two-leaf) walls are stronger and quieter but use twice as many bricks.
