    Abstract

    It has long been known that highly conductive protrusions through insulation (thermal bridges) are detrimental to the overall resistance of a wall system. Equally well known is the fact that fibrous insulation must be placed against an impervious membrane to avoid the detrimental effect of air circulation through the insulation by convection. Although thermal bridging has received much design attention, it has recently come to light that actual placement of the insulation and design for its proper placement may be the most serious problem. This paper describes tests on typical commercial building systems, illustrating the problems and proposed solutions.
