Clay Hollow Blocks
Engineered for Real India
Ecotherm by Prayag Clay Products are precision-engineered clay hollow blocks — the first of their kind manufactured in North India. Made from sustainably sourced premium clay, designed for both load-bearing and partition walls.
A wrong choice of building material is carried for the lifetime of a structure. Ecotherm makes sure that choice works harder — thermally, structurally, and economically — from Day 1 to decade 3.
First in North India
Pioneer manufacturer of clay hollow blocks in the region
ISO 9001:2015
Certified precision manufacturing under stringent QC
Thermal Performance
Superior U-values keep your space 5–7°C cooler naturally
Two Series. Every Wall Covered.
Ecotherm comes in Vertical and Horizontal Perforation series — each engineered for specific wall types and structural requirements.
VP SeriesVertical Perforation (VP)
Holes run vertically through the block. Designed for load-bearing walls with extraordinary compressive strength. Interlocking design means faster laying, less mortar, and can even be left as an exposed/facing brick.
HP SeriesHorizontal 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.
Built for India's Climate & Builders
From block engineering to on-site advantages — here's why Ecotherm is the smarter call in 2026.

5 Reasons Builders Are Switching
Still using solid bricks? Here's what you're missing.
60% Lighter
Less structural dead load means safer construction — especially important in seismic zones. Your RCC frame works less, lasts longer.
Ecotherm in Action












Conventional Brick Costs You Twice
Most homeowners don't realise they're overpaying — once at construction, and every single month on their electricity bill.
Excessive Plaster & Mortar
Standard solid brick requires 20mm plaster and full mortar beds — eating into your material budget on every square metre.
Slow Construction
Heavy, irregular bricks slow masonry work, raise labour costs, and extend timelines. Every extra week adds real cost.
Poor Thermal Performance
Solid brick walls trap heat. Every summer your AC works harder — and your bill climbs. That's lakhs lost over 5 years.
Higher Electricity Usage
Without wall insulation, cooling systems run 26% harder — thousands wasted on electricity every single year.
Water Wastage
Traditional bricks absorb more water during construction and curing — driving up usage and project costs unnecessarily.
High Labour Costs
Conventional brick laying is slow and manual. More workers, more days — your labour bill balloons with every extra day.
Frequent Maintenance
Solid brick walls crack under thermal expansion and seismic stress. Maintenance costs compound silently over decades.
Cooling Inefficiency
AC units in poorly insulated buildings cycle far more often, reducing equipment life and increasing power consumption.
Long-term Operating Losses
The true cost of conventional brick isn't just at construction — it's a recurring drain on your electricity bill for decades.
Every one of these problems has a solution — and it's called Ecotherm.
Two Streams of Real Savings
Based on a standard G+2 — 3BHK project in Delhi-NCR, comparing Ecotherm vs conventional solid brick construction.

5-Year Electricity Savings
When Day 1 savings are compounded at 7% over 5 years, your total advantage crosses ₹4.4 Lakh — on a single G+2 home.

Surface & Bed Prep
Clean the surface. Lay a thin mortar bed — just 10mm is needed, versus 20–25mm for conventional brick.
Block Placement
Ecotherm's interlocking design means blocks self-align. No complex levelling — just drop, align, and move on.
Minimal Mortar Joints
Thin joints save up to 62% on mortar use. Less mixing, less waiting, more building — 6× faster overall.
Finish Ready in 8mm
Ecotherm's true surface needs only 8mm plaster versus 20mm on traditional brick — finish-ready sooner.
Ecotherm vs Conventional Brick
A clear, honest comparison across all the metrics that affect your build cost and long-term comfort.
