When planning to design and construct steel structures such as warehouses, factories, exhibition halls, or commercial buildings, one key question always comes up: Which insulation material should you choose?
The answer often lies in selecting the right sandwich panel, a core element in modern construction that combines strength, thermal insulation, and sound protection.

At Hasanoglu, we supply two main types of sandwich panels: PUR and PIR. While they may look similar, each type offers specific advantages depending on the needs of your project.
What is PUR Sandwich Panel?
PUR sandwich panels are made from Polyurethane Foam (PUR) and are among the most widely used solutions in industrial and commercial construction.
Key Benefits:
-
Excellent thermal insulation that helps maintain internal building temperature.
-
Good moisture resistance, minimizing condensation or water leakage issues.
-
Lightweight and easy to install, which speeds up construction time.
-
An economical solution, ideal for warehouses and standard buildings without highly demanding requirements.
What is PIR Sandwich Panel?
PIR sandwich panels represent a more advanced generation, made from Polyisocyanurate Foam (PIR).
Key Benefits:
-
Provides 20% higher thermal insulation performance compared to PUR.
-
Superior fire resistance, making it a safer option for sensitive projects.
-
Maintains its insulation properties for longer, even under challenging conditions.
-
Ideal for high-spec projects such as food processing plants, laboratories, cold storage facilities, or buildings exposed to elevated heat.
PUR vs. PIR: A Quick Comparison
| Feature | PUR | PIR |
|---|---|---|
| Thermal Insulation | Excellent | 20% higher than PUR |
| Fire Resistance | Moderate | High |
| Cost | More economical | Slightly higher (for added safety) |
| Best Applications | Warehouses, standard buildings | Sensitive or high-risk projects |
Which One Should You Choose?
-
For standard warehouses or conventional buildings, PUR panels are a cost-effective and reliable choice.
-
For projects that require maximum safety and high performance against fire and heat, PIR panels are the right investment.
