When designing and constructing a steel building, insulation is one of the most critical components that determine your building’s performance and long-term efficiency. But how do you choose the right type of sandwich panel for your specific project?
At Hasanoglu, we offer a wide range of sandwich panels with different core materials:
EPS – PUR – Rock Wool
In this article, we’ll help you understand the differences and guide you in selecting the panel that best fits your needs.
1. EPS – The Budget-Friendly Thermal Insulation
EPS (Expanded Polystyrene) panels are a cost-effective option for projects that require basic thermal insulation.
Features:
- Good thermal insulation.
- Lightweight and easy to install.
- Most economical option.
Best suited for:
- Warehouses and storage units.
- Poultry farms and agricultural facilities.
- Temporary or low-cost buildings.
🔺 Not recommended if:
- The project requires fire resistance or sound insulation.
2. PUR – The Highest Thermal Performance
PUR (Polyurethane) panels offer the best thermal insulation performance among all panel types, with excellent energy efficiency.
Features:
- Superior thermal conductivity.
- Ideal for energy-saving applications.
- Lightweight with high insulating power.
Best suited for:
- Cold storage rooms and freezers.
- Factories and buildings in hot desert climates.
- Projects with high electricity costs and energy-saving goals.
🔺 Considerations:
- More expensive than EPS.
- Moderate sound and fire insulation.
3. Rock Wool – For Fire Safety and Acoustic Insulation
Rock Wool panels are the top choice when fire resistance and sound insulation are key priorities.
Features:
- Highly fire-resistant (up to 1000°C).
- Excellent acoustic insulation.
- Dense and strong structure.
Best suited for:
- Industrial plants and workshops.
- Power stations or hazardous zones.
- Buildings in noisy areas or with strict fire safety codes.
🔺 Considerations:
- Higher cost.
- Heavier weight, which may affect structure and transport.
Quick Comparison Table:
| Feature | EPS | PUR | Rock Wool |
| Thermal Insulation | Good | Excellent | Good |
| Sound Insulation | Poor | Moderate | Excellent |
| Fire Resistance | Poor | Poor | Excellent |
| Weight | Very Light | Light | Heavy |
| Cost | Budget-Friendly | Medium to High | High |
