• Abstract:

  An investigation of heat transmission characteristics of masonry and wood-frame walls is described. Steady-state and dynamic tests were conducted using a calibrated hot box. Results indicate that thermal inertia has a considerable effect on heat transfer characteristics. Thermal lag increased with increased wall weight. A significant eduction in dynamic energy requirements occurred as thermal resistance was increased to 8 hr-ft.².F/Btu(1.41 K-m²/W). Increases beyond this value did not result in corresponding reductions in energy requirements.
