Thermal performance of frame walls

Studies of the thermal performance of frame walls previously reported have been extended to include an investigation of the effects produced by inserting horizontal blocking in walls with air spaces. Data are presented which illustrate the vertical variations in temperatures and heat flow rates resulting from convection within frame walls with blocking at mid-height when insulation is ideally applied and when insulation installed to form two air spaces is improperly scaled. Data showing the horizontal variation in surface temperature across walls due to the presence of studding with various forms of insulation are also given.
