This chapter presents thermal and water vapor transmission data based on steady-state or equilibrium conditions. This information can be used in the simplified calculation methods described in Chapter 27, or in software-based methods that develop step-wise steady-state conditions into a time-dependent solution. Chapter 4 covers heat transfer under transient or changing temperature conditions. Chapter 25 discusses combined heat-air-moisture transport. For information on insulation for mechanical systems, see Chapter 23.
