What are 8-hole clay bricks? Why are they the best choice for projects requiring accelerated implementation?
8-hole brick This is the largest Jumbo Size clay brick in our clay brick product line. 7 × 11 × 25 cm. — One block has a surface area of 11 × 25 = 275 sq. cm. Compared to a small 2-hole brick (6 × 14 = 84 sq. cm.), this means that… One 8-hole brick can replace 4-5 standard bricks.
Only 25-28 bricks per square meter are needed, compared to 120-130 bricks of smaller size.
Reduce labor costs by up to 70-80% per wall area — crucial for large projects.
The 8 air vents act as multi-layered air gaps, providing better thermal insulation than bricks with 2-3 vents, resulting in a cooler house. Suitable for exterior walls requiring both insulation and thermal insulation. Speed of construction and Thermal insulation performance

Key features of 8-hole clay bricks (AY Contento)
Fastest construction speed in the line — maximum labor cost savings.
Using only 25-28 bricks per square meter, which is 5 times fewer than small bricks, allows for faster completion of construction, reducing time and labor costs compared to all other brick types. Ideal for projects requiring urgent deadlines.
The best way to keep your home cool — 8 Air Gap
The 8-hole air vents create multiple layers of natural insulation, slowing down heat transfer from the outside more effectively than bricks with 2-3 holes. This results in a cooler home, reduces the burden on air conditioning, and saves on electricity bills in the long run.
11 cm thick walls — sturdy and strong.
The 11 cm height results in a thicker and more stable wall than standard bricks, making it suitable for exterior walls exposed to weather and wind pressure, or the lower floors of buildings.
A sturdy loft-style exposed brick wall — larger than typical exposed brick.
If built as an exposed brickwork without plastering, larger blocks than 4-hole bricks create a more striking, robust, and industrial look, ideal for loft-style projects that require a clear statement.

Applications
- Construction projects requiring accelerated deadlines — reducing the number of bricks needed by five times.
- Large exterior walls of buildings requiring high thermal insulation and thick walls.
- Factories, warehouses, and storage facilities requiring sturdy and quickly constructed walls.
- Ground floor commercial buildings requiring thicker, load-bearing walls.
- An industrial-style loft construction project that requires striking brick sizes.
Important Notes Before Ordering
| section | details |
|---|---|
| Weight of the block | 2.5 kg/block — Heavier than other models. It's recommended to have a builder experienced in constructing large bricks. |
| Volume transported per trip | Fewer transport trips than smaller models due to its heavier weight — the number of transport trips should be planned correctly. |
| Shipping cost per square meter. | The shipping cost per block may be higher, but when calculated per actual wall area, it's still worthwhile because very few blocks are needed. |
| Supporting structure | An 8-hole wall is heavier per square meter than a wall made of small bricks — consult an engineer for load-bearing wall designs. |
Transportation
| Vehicle type | Quantity (approximate) | Suitable for |
|---|---|---|
| 6 wheel truck | ~6,000–8,000 pieces | Small-to-medium scale construction projects |
| 10 wheel truck | ~12,000–15,000 pieces | Medium-sized projects |
| 18-wheeler truck (trailer) | ~20,000+ pieces | Large-scale projects |
Frequently Asked Questions (FAQ)
Approximately 5 times faster compared to small 2-hole bricks — only 25-28 8-hole bricks are needed per sq.m. compared to 120-130 bricks. This significantly reduces the number of bricks that need to be lifted and laid, allowing builders to work much faster.
Weighing 2.5 kg per block, which is heavier than the smaller model but still manageable by construction workers. Compared to AAC concrete blocks that weigh 6-14 kg per block, these 8-hole blocks are significantly lighter. It is recommended that construction workers adjust their laying techniques slightly due to their larger size compared to standard blocks.
To build a wall 11 cm thick, approximately 25-28 bricks per square meter are needed, including a mortar joint of approximately 1.5 cm. It is recommended to order extra (5-7%). Red Brick calculation program
These are beautiful. Their larger size compared to typical exposed brick gives them dimension and a robust look, creating a distinctive Industrial Loft style. They stand out from the popular four-hole exposed bricks and are perfect for projects that want a strong statement.
