The thermal insulation of the PU sandwich panel
3
The thermal insulation of Polyurethane (PU) sandwich panels is one of their key advantages, making them highly effective for temperature control in various applications such as cold storage, warehouses, and buildings.
PU foam has a thermal conductivity (λ) of around 0.019 – 0.025 W/m·K, which is lower than many other insulating materials like EPS or mineral wool.
This ensures excellent thermal resistance and energy efficiency.
PU sandwich panels provide high R-values, meaning they resist heat transfer effectively.
This helps in maintaining stable indoor temperatures with minimal energy consumption.
The polyurethane foam core has a closed-cell structure, reducing air permeability and enhancing thermal insulation.
It also prevents moisture absorption, maintaining insulation performance over time.
PU panels significantly reduce heating and cooling costs, making them ideal for cold rooms, food storage, industrial buildings, and prefab houses.
Their high insulation efficiency ensures compliance with energy-saving regulations.
Compared to other insulating materials, PU panels offer superior insulation with a thinner panel thickness, optimizing space usage while maintaining high thermal resistance.
PU sandwich panels can operate effectively in extreme conditions, withstanding temperatures as low as -50°C (for cold storage) and up to +80°C in standard applications.
