Insulating basements can be far more intricate as a consequence of their much larger dimensions and prospective for moisture concerns, especially if beneath the drinking water table.
If the joist bays are completely filled with insulation, the main difference in temperature among the subfloor immediately higher than a joist and also the subfloor above the center of a joist bay — a distinction in temperature because of thermal bridging in the joists — will be 1.
