Stationary and dynamic heat and mass transfer analyses of building components are an essential part of energy efficient design of new and retrofitted buildings. Generally, a single constant thermal conductivity value is assumed for each material layer in construction components. However, the variability of thermal conductivity may depend on many factors; temperature and moisture content are among the most relevant ones.

The article provides a thorough review of the main conventional and advanced building insulation materials, examining and comparing their characteristics and performances, including costs and environmental features, and illustrating the most suitable solutions to increase the energy and environmental efficiency of new and existing buildings according to the operating and application conditions.
