What Are 10 Hole Bricks?
10 hole bricks — also referred to as 10 perforation bricks, 10-core bricks, or high-perforation bricks — represent the most advanced category of perforated clay bricks. With ten holes running through their length, these bricks have a perforation ratio of 45–55% of total volume, making them the lightest, most thermally efficient, and most eco-friendly option among traditional clay bricks.
These bricks are the preferred choice in green building projects, IGBC-certified buildings, and modern high-rise construction across urban India.

Key Benefits of 10 Hole Bricks
1. Maximum Weight Reduction
At just 1.4–1.9 kg per brick, 10 hole bricks are 35–45% lighter than solid bricks. For a 10-storey apartment with 50,000 sq ft of wall area, this can reduce the masonry dead load by 150–200 tonnes — directly reducing column sizes, beam sizes, and foundation costs.
2. Best-in-Class Thermal Insulation
With a thermal conductivity of just 0.35–0.45 W/m·K (compared to 0.7 W/m·K for solid bricks), 10 hole brick walls keep interiors significantly cooler. In Indian climate conditions:
- Summer interior temperatures can be 5–8 degrees Celsius lower vs solid brick construction
- Air conditioning load reduced by 12–18%
- Annual electricity savings: Rs 8,000–Rs 15,000 per 1,000 sq ft of living space
3. Green Building Compliance
10 hole bricks help earn points in:
- IGBC Green Homes rating — Materials category
- GRIHA (Green Rating for Integrated Habitat Assessment)
- LEED India — Materials and Resources credits
4. Sound Attenuation
The 10 air channels create a honeycomb-like structure that absorbs sound waves. Laboratory tests show 10 hole brick walls achieve STC (Sound Transmission Class) ratings 3–5 points higher than equivalent solid brick walls.

GST on 10 Hole Bricks (2026): 10 hole clay bricks attract 12% GST under HSN code 6901. Ask your supplier for a GST-inclusive quote and insist on a proper invoice. For large commercial projects, ITC (Input Tax Credit) on brick purchases can offset a significant portion of the GST paid.
When to Choose 10 Hole Bricks
Before deciding, use our brick quantity calculator to estimate total cost for your project. Then choose based on your requirement:
Choose 10 hole bricks when:
- Building a high-rise structure (G+5 and above)
- Your project requires green building certification (IGBC, GRIHA, LEED)
- You need superior thermal comfort in hot climate regions like Rajasthan, Gujarat, Andhra Pradesh
- The building has strict air conditioning load targets
- You want to reduce structural cost through dead load savings
Do NOT use 10 hole bricks for:
- Foundation or plinth below ground level — use solid or 3 hole bricks for these
- Any load-bearing wall application — 3 hole bricks (IS 1077) are better suited for limited load-bearing use
- Retaining walls or boundary walls exposed to lateral soil pressure
- Wet areas like bathrooms and kitchens

Naresh Sihag, BricksStreet: "10 hole bricks cost Rs 1–2 more per brick, but in a 50-flat apartment project, this extra cost is fully recovered in structural savings alone. When you add 20-year energy savings, it is a no-brainer for any serious developer."
Quality Testing for 10 Hole Bricks
10 hole bricks require additional quality checks due to their thinner web walls:

- Shell Thickness: Minimum 20 mm outer wall thickness
- Uniformity: All 10 holes must be consistent in size and position
- Compressive Strength Test: Minimum 5 N/mm² (lab-certified)
- Visual Inspection: No cracks in web walls, uniform red color, no black spots (under-fired)
Frequently Asked Questions — 10 Hole Bricks
What is the price of 10 hole bricks in India in 2026?
10 hole brick prices in 2026 range from Rs 7 to Rs 15 per brick depending on location. Delhi NCR: Rs 9,000–Rs 12,500 per 1000. Rajasthan: Rs 7,500–Rs 10,000 per 1000 (most affordable). Maharashtra: Rs 11,000–Rs 15,000 per 1000 (most expensive). All prices subject to 12% GST and transport charges.
Are 10 hole bricks suitable for load-bearing walls?
No. 10 hole bricks are NOT recommended for load-bearing wall construction. Their high perforation ratio (45–55%) significantly reduces cross-sectional area available for load transfer. They are designed exclusively for use as infill walls in RCC (Reinforced Concrete Cement) frame structures, where columns and beams carry all structural loads. Using 10 hole bricks in load-bearing applications is a structural safety risk.
10 hole bricks vs AAC blocks — which is better in 2026?
Both have their place. 10 hole bricks are 30–40% cheaper per unit, have higher compressive strength, and are more widely available. AAC blocks are lighter, offer better thermal and sound insulation, and require less mortar. For budget urban construction, 10 hole bricks win on cost. Also compare: 8 hole bricks vs AAC blocks — often a better balance for mid-rise buildings. For premium projects targeting green ratings or maximum energy efficiency, AAC blocks are preferred. In 2026, AAC blocks cost Rs 55–Rs 75 per block vs Rs 9–Rs 15 per 10 hole brick — but one AAC block replaces approximately 8–10 bricks.
How much cooler is a 10 hole brick wall vs a solid brick wall?
In typical Indian climate conditions, walls built with 10 hole bricks maintain interior temperatures 5–8 degrees Celsius lower than equivalent solid brick walls during peak summer. This is due to the lower thermal conductivity of 0.35–0.45 W/m·K vs 0.7 W/m·K for solid bricks. The result is a 12–18% reduction in air conditioning load, which translates to real savings of Rs 8,000–Rs 15,000 per year per 1,000 sq ft of living area.
What is the minimum shell thickness for 10 hole bricks as per IS 2222?
As per IS 2222:1979, 10 hole bricks must have a minimum shell (outer wall) thickness of 20mm and a minimum web (partition between holes) thickness of 13mm. These minimum dimensions ensure the brick retains adequate strength despite the high perforation ratio. Always check these dimensions when buying — sub-standard kilns often reduce shell thickness to cut costs.
Do 10 hole bricks help get IGBC green building rating?
Yes. 10 hole bricks contribute to green building ratings in India, specifically under the IGBC Green Homes and GRIHA frameworks, in the Materials and Resources category. The reduced clay consumption per brick (due to 45–55% perforation) lowers the embodied energy of the material. However, the specific rating points depend on the overall project specification — consult a certified green building professional for your project.
