- Abstract
- Four concrete floors laid on the ground and three concrete and one wood floor laid over crawl spaces were tested for heat-transfer properties in a special structure provided for the purpose. It was found that the heat loss of the floors laid on the ground was decreased by insulating the edges; that the heat loss through the center of such floors is relatively small when the enclosing structure is continuously heated; that the edge loss for a wood floor laid over a crawl space is small; and that the edge loss for an insulated concrete floor laid over a crawl space was considerable. Observed ground temperatures at various depths, down to 13 ft below the surface, are reported in the paper and some factors are suggested for estimating floor heat losses.
