EPiC database - Polyurethane (PU) rigid foam insulation

This material is part of the free Environmental Performance in Construction (EPiC) Database. The EPiC Database contains embodied environmental flow coefficients for 250+ construction materials using a comprehensive hybrid life cycle inventory approach.

Polyurethane (PU) is a polymer with a low density, low thermal conductivity and high durability.

PU is produced by mixing a stream of isocyanate and a stream of polyol, including any other additives. The proportion of each stream in the mix is often used to alter the material properties. The resulting mixture is poured into a mould or onto a surface. Once cured, the PU is demoulded.

PU insulation consists of rigid foam panels that are used for high-performance insulation.
