Ecowall by Sristi Ventures is an insulated wall panel system designed to provide excellent thermal insulation, faster construction, and improved indoor comfort. With its EPS (Expanded Polystyrene) insulated core, Ecowall offers an energy-efficient and lightweight wall solution for residential, commercial, industrial, and prefabricated buildings.
Thermal Insulation Benefits
EPS is an excellent thermal insulator because it contains about 98% trapped air.
Key benefits:
- Low thermal conductivity: Typically, 0.032–0.038 W/m·K, reducing heat transfer.
- Energy savings: Can reduce cooling and heating energy consumption by 20–50%, depending on the building design and climate.
- Comfortable indoor temperatures:Helps maintain stable indoor temperatures throughout the day.
- Reduced HVAC load: Air conditioning and heating systems operate more efficiently.
- Moisture resistance:EPS absorbs very little water, so its insulating performance remains stable over time.
Typical thermal resistance (R-value):
| EPS Thickness | Approximate R-value |
|---|---|
|
50 mm 75 mm 100 mm 150 mm |
1.3–1.6 m²·K/W 2.0–2.4 m²·K/W 2.6–3.2 m²·K/W 4.0–4.8 m²·K/W |
Greater thickness provides better thermal insulation.
Sound Insulation Benefits
EPS is not primarily an acoustic material, but sandwich panels can still provide moderate sound reduction.
Typical sound reduction (STC/Rw):
| Panel Type | Typical Sound Reduction |
|---|---|
|
50 mm EPS sandwich panel 75 mm EPS sandwich panel 100 mm EPS sandwich panel |
22–28 dB 25–30 dB 28–35 dB |
What EPS does well:
- Reduces normal outdoor noise.
- Damps echoes to a limited extent.
- Suitable for offices, warehouses, classrooms, temporary buildings, and residential partition walls.
Limitations:
- Less effective against low-frequency sounds (heavy traffic, machinery, bass).
- Inferior acoustic performance compared with mineral wool (rock wool) sandwich panels.

Best Applications for EPS Panel Walls
EPS panel walls are well suited for:
- Residential homes
- Office partitions
- Warehouses
- Site offices
- Cold rooms (with appropriate thickness)
- Modular and prefabricated buildings
When EPS May Not Be the Best Choice
If your project requires:
- High levels of soundproofing (recording studios, cinemas, hospitals)
- Superior fire resistance
- Industrial noise control
then rock wool sandwich panels are generally a better option.
Summary
- Thermal insulation: Excellent; significantly reduces heat transfer and energy use.
- Sound insulation: Moderate; suitable for everyday environments but not for high-noise applications.
- Cost: One of the most economical insulated wall systems.
- Best use: Buildings where thermal efficiency and lightweight construction are priorities, with moderate acoustic requirements.
Benefits include:
- Maintains comfortable indoor temperatures in both hot and cold climates.
- Reduces dependence on air conditioning and heating systems.
- Helps lower overall energy consumption and operating costs.
- Minimizes heat gain during summer and heat loss during winter.
- Contributes to sustainable and energy-efficient building design.
Sound Insulation
The multi-layer construction of Ecowall helps reduce the transmission of airborne noise, creating quieter indoor environments.
Benefits include:
- Reduces external noise from traffic and surrounding activities.
- Improves privacy between rooms and workspaces.
- Enhances acoustic comfort in homes, offices, schools, hospitals, and commercial buildings.
- Suitable for environments requiring moderate sound insulation.
Additional Advantages
- Lightweight construction reduces structural load.
- Fast and clean installation compared to conventional masonry.
- Factory-manufactured panels ensure consistent quality and dimensional accuracy.
- Durable and low-maintenance wall system.
- Moisture-resistant EPS core helps maintain long-term insulation performance.
- Environmentally conscious solution that supports energy-efficient construction.
