Cold Insulation

Polyurethane Board

Polyurethane Board is a rigid thermal insulation material in board form, made from polyurethane (PU) with a closed-cell structure. It is produced through a chemical reaction process that creates foam with controlled density and excellent thermal insulation performance.

With its very low thermal conductivity, Polyurethane Board is one of the most efficient insulation solutions for low to medium temperature applications, and is widely used in systems requiring energy efficiency and stable temperature control.

Characteristics & Advantages

• Very Low Thermal Conductivity – Provides maximum insulation performance
• Closed-Cell Structure – Minimizes water and vapor absorption
• Lightweight & Strong – Offers a good strength-to-weight ratio
• Good Dimensional Stability – Resistant to deformation
• High Energy Efficiency – Significantly reduces energy loss
• Easy Installation – Board form allows neat and efficient installation
• Moisture Resistant – Suitable for high-humidity environments
• Available with Facing – Aluminium foil, kraft paper, or metal sheet
