Your Walls Will Cost You ₹3.7 Lakh — Unless You Change Them.
Ecotherm clay hollow blocks save ₹1.76 Lakh on construction Day 1 — and keep reducing your AC bills by 26% every year. Engineered for India's climate by Prayag Clay Products, est. 1937.
*Savings are indicative estimates based on standard project benchmarks. Actual results may vary by 15–20% depending on project specifications, location, and contractor practices.
*Figures shown are modelled estimates for a standard G+2 3BHK in Delhi-NCR. Actual savings may vary by 15–20% based on project size, location, material rates, and usage patterns.
India's First EPD-Certified
Verified under International EPD System (ISO 14025, EN 15804). The only Indian brick manufacturer with this global environmental certification.
HCL Climaforce Recognition
"The most advanced sustainable thermal insulating clay product in the world." A global distinction no other Indian manufacturer holds.
Thermal Performance
Superior U-values (VP 150: 1.6 W/m²K vs solid brick: 2.5) keep your space 5–7°C cooler naturally — reducing AC dependency by 26%.
Vertical Perforation (VP)
Holes run vertically through the block. Designed for load-bearing outer walls with compressive strength up to 15 N/mm². Interlocking design eliminates vertical mortar joints — 6× faster laying. Can be left as exposed facing brick.
Horizontal Perforation (HP)
Holes run horizontally for superior acoustic and thermal insulation. Ideal for non-load-bearing partition walls. Lightweight, fire-resistant, and perfect for interior divisions in residential and commercial projects.

Your Builder Saved ₹99,167. You'll Pay ₹3.7 Lakh for That Decision.
When your builder picks "cheaper" solid bricks, they save ₹99,167 on material. But YOU end up paying ₹1.76 Lakh extra on mortar, plaster, and labour — plus ₹1.94 Lakh in wasted AC electricity over 5 years.
*Cost estimates are based on Delhi-NCR 2026 benchmark rates for a G+2 3BHK project. Your actual figures may differ by 15–20% depending on region, project scale, and contractor.
60% More Plaster
Solid brick requires 20mm plaster per side — Ecotherm needs just 8mm. That's ₹58,348 wasted on a single G+2 project.
6× Slower Masonry
Heavy, irregular bricks slow masonry work. Every extra week on-site adds real cost in labour, supervision, and equipment rental.
Walls That Trap Heat
Solid brick walls let in 3,716 watts of continuous heat in peak summer. Your AC fights the wall before it cools your room.
26% Higher AC Bills
Without insulating air pockets, your cooling system runs 26% harder — ₹35,000 wasted per year on electricity in a Delhi G+2 home.
Moisture Damage
Standard bricks absorb 12–16% water. Ecotherm stays below 11% — meaning fewer cracks, less seepage, lower maintenance for decades.
Compounding Losses
Delhi electricity tariff rises ~5% per year. The ₹1.93L you lose in 5 years becomes ₹2.8L in 10. Every month of delay locks in higher bills.
Upfront Construction Savings
Ongoing AC Bill Reduction
*Combined savings are approximate projections using steady-state thermal modelling and Delhi-NCR 2026 market rates. Actual outcomes may vary by 15–20% based on your specific project parameters.
Delhi electricity tariff has risen ~5% every year since 2019. The ₹1.93L you save in 5 years becomes ₹2.8L in 10 years. Every month you delay building with Ecotherm, you lock in higher AC bills for the life of your home. The cost of waiting is real.

Results are approximate estimates based on standardised construction and energy models. Actual savings may vary by 15–20% depending on project size, location, material rates, and contractor practices. Calculations benchmarked across Delhi, UP, AP, and Maharashtra projects.
Surface & Bed Prep
Clean the surface. Lay a thin mortar bed — just 10mm horizontal groove, versus 20–25mm for conventional brick.
Block Placement
Ecotherm's interlocking design means blocks self-align. No vertical mortar joints. Drop, align, and move on.
Minimal Mortar
Horizontal groove joints only — saving 60% on mortar. Less mixing, less waiting, 6× faster overall.
Finish in 8mm
Ecotherm's dimensional accuracy needs only 8mm plaster vs 20mm on solid brick — finish-ready sooner.
Individual Homebuilders
Building your G+1 or G+2 home? Save ₹1.76L on Day 1 and cut your AC bill by 26% every year. No minimum order.
Architects & Consultants
Specify smarter. Ecotherm meets GRIHA/IGBC norms, reduces structural load calculations, and delivers verified U-values for green building submissions.
Contractors & Builders
6× faster masonry = more projects per season. Standard masons, standard tools. Your team builds more in less time.
Developers & PMC Firms
Scale savings across units. Commercial projects save ₹68/sqft of built-up. Green certification adds 8–15% rental premium.
