Thermal conductivity pipe insulation material

Thermal conductivity of the insulation material around the pipe in the center of a heat source, e.g. a district heat pipe. Values for PUR is taken from standard EN 253:2009 and typical values for mineral and glass wool are taken from the publication 'A Study on Insulation Characteristics of Glass Wool and Mineral Wool Coated with a Polysiloxane Agent' by Chan-Ki Jeon et.al., Hindawi (2017).
