CALCULATED VERSUS MEASURED THERMAL RESISTANCES OF SIMULATED BUILDING WALLS INCORPORATING AIR SPACES.

Author(s) : GREASON D. M.

Summary

MEASURED AND CALCULATED VALUES FOR WALLS WITHOUT AIR SPACES WERE IN GOOD AGREEMENT, BUT MEASURED VALUES WERE SIGNIFICANTLY LOWER THAN CALCULATED VALUES FOR MOST WALLS INCORPORATING AIR SPACES. THE THERMAL RESISTANCES OF TYPICAL AIR SPACES IN CONSTRUCTION ARE SIGNIFICANTLY LOWER THAN LITERATURE VALUES FOR PERFECT AIR SPACES. DIRECT USE OF SUCH VALUES IN DESIGN CALCULATIONS CAN LEAD TO SERIOUS ERROR.
