Polyurethane (PU) Insulated sandwich panel is a composite building material. It is made up of a rigid core sandwiched between two metal sheets. Rigid polyurethane (PU) foam is the internationally recognized best construction material where heat insulation properties coupled with strength are required, like in Pre-engineered buildings, warehouses and cold-chain solutions. PU panel has low thermal conductivity (R-value). R-value is an important measure of resistance to heat flow through a given thickness of material. R-value figures of PU panels are given in the table (The lower the better).

Sandwich Panels are typical single piece, modular, factory engineered units comprising of two metal faces sandwiching a highly efficient insulating materials like Polyurethane or Polystyrene. These are high performance building panels used for residential, commercial as well as industrial buildings. EKN Cooling System manufacturing wide range of Water Proof, Tamper Proof, Corrosion Resistant, Durable Coating and trustworthy Polyurethane (PU) & Expanded Polystyrene (EPS) Sandwich Panels, Cold Storage Room, Modular Portable Cabin, Pre Engineering Building and Industrial Fabrications both in Mild Steel & Food Grade Stainless Steel.
