What are large, three-hole clay bricks? Why are they considered an "innovation for cool homes"?
Jumbo Hollow Brick (Three-hole brick) These are extra-large fired clay bricks, manufactured using a system... Extrusion This process forces the clay through a mold under high pressure, resulting in bricks with uniform size, high density, and more precise shapes than typical hand-molded bricks.
The key features that distinguish it from ordinary clay bricks are: 3 air vents These holes, drilled through the entire length of the block, are not just for weight reduction — but also serve as... Air Gap This is an excellent natural insulator that slows down heat transfer from the outside, based on the same principle as... The Department of Alternative Energy Development recommends: To reduce energy consumption in buildings.

Key features: Large, three-hole clay bricks (AY Contento)
A cooler home — save on electricity bills.
The three air gaps act as natural insulation, slowing down heat from sunlight from easily penetrating the walls. This results in a cooler house compared to solid brick walls, reducing the burden on air conditioning and saving on electricity bills in the long run.
Construction is 3 times faster — saving on labor costs.
These bricks are three times larger than typical clay bricks, requiring only 40-45 bricks per square meter compared to 85-90 standard bricks. This allows for faster construction, significantly reducing labor costs and building time.
Stronger than lightweight — more durable.
Fired clay at high temperatures results in walls with high strength, capable of withstanding drilling, screwing, and hanging furniture better than lightweight concrete blocks, and offering superior long-term resistance to moisture.
Uniform size — Extrusion System
Produced using an extrusion system, which forces clay through a high-pressure mold, resulting in uniformly sized blocks with even grooves, making the process easier and requiring less mortar.
Comparison: Three-hole clay bricks vs. lightweight concrete blocks vs. regular clay bricks
| section | Large 3-hole brick | Lightweight concrete blocks (AAC) | Ordinary clay bricks |
|---|---|---|---|
| Size | 6 x 10 x 20 cm (Jumbo) | Available in various sizes | 4 x 6.5 x 14 cm (smaller) |
| Block/sq.m. | 40–45 pieces | 12–15 pieces | 85–90 pieces (or more) |
| Speed of construction | Fast (large lump) | Very fast (larger piece). | Slow (small lump) |
| insulation | Good (Air Gap 3 holes) | Very good (AAC structure) | moderate |
| Strength | Tall (earthenware) | Lower (difficult to drill) | Tall (earthenware) |
| Fastening/Drilling | Good job | It's difficult; it requires a special plug. | Good job |
| Moisture resistant | good | Low (high water absorption) | good |
| Price per square meter (materials) | good value | More expensive | Cheapest |
Applications
- Exterior walls of buildings, housing estates, and townhouses that require a cool and energy-efficient home environment.
- A partition wall requiring high strength to support hanging items and pipe drilling.
- Medium to large-scale construction projects that require reduction in time and labor costs.
- Exposed brickwork requiring uniform dimensions from an extrusion system.
- replaceLightweight concrete blocksIn jobs requiring greater strength.

Frequently Asked Questions (FAQ)
Large, three-hole clay bricks measure 6 x 10 x 20 cm, three times larger than standard clay bricks (4 x 6.5 x 14 cm). This results in faster wall construction, requires less labor, and the three air holes help insulate against heat, keeping the house cooler than with solid bricks.
That's true — these holes act as air gaps, a natural insulation that slows down heat transfer from the outer walls into the building. It's the same principle as the thermal insulation recommended by the Department of Alternative Energy Development. The result is walls absorbing less heat, the air conditioner works less, and electricity bills are lower.
For a 10 cm thick wall (facing the long side), approximately 40–45 bricks per square meter are needed, including a 1–1.5 cm mortar joint. We recommend ordering extra 5% bricks to account for broken pieces. Use our brick calculator.
Depending on the usage — if needed. Strong, drill-resistant, and moisture-resistant. Three-hole clay bricks are clearly better, if needed. Maximum thermal insulation and very lightweight. Lightweight concrete blocks have advantages, but they are more expensive and require more drilling and installation.

Yes, clay bricks are stronger than lightweight concrete blocks. They can be drilled and used with standard plugs and screws without needing special plugs, making them suitable for hanging cabinets, clothes rails, or built-in wall fixtures.

Good service, fast delivery. If you buy a lot, you get free gifts.
speak loud –
The price was good, so I tried ordering 10,000 pieces. I'll probably order from here again when I get more calls.
Sritrakul –
The bricks are beautiful. Fast delivery. The sales person is easy to talk to and not too busy.
Ek –
To be honest, I bought this because of the sales. I like people who answer quickly. I don't know why many salespeople suddenly disappear after a day before I can answer. I'm so confused.
Chitthiang –
I bought it because it was on sale, that's all. The price is no different than anywhere else.
