The primary function of any insulation material is thermal performance. Polyurethane insulation has a very low thermal conductivity or lambda, typically starting from as low as 0.022 W/m.K, making it one of the most effective insulation materials readily available today for a wide range of applications.
However, high thermal performance is just one of the benefits of this material; there are a number of other key characteristics which make polyurethane a truly premium insulant.
