Thermal radiation is the movement of heat energy from a warm object to a cooler item through space. A common example involves an occupant standing in front of a window and experiencing cold during the winter. In this instance, one’s body is radiating heat to the cooler window surface.
The importance of limiting heat transfer is not only to promote energy efficiency and occupant comfort, but also to reduce the potential for condensation within building assemblies. When moist air comes into contact with rcs data nonporous surfaces below the dewpoint, water can condense and create frost or water droplets (Figure 2).
by their resistance to heat flow, otherwise known as R-value. The higher the R-value, the greater the resistance to heat transfer. Another measure associated with heat transfer is the U-factor, typically associated with opaque assemblies or fenestration products. The smaller the U-factor, the better the product limits heat transfer.
