U Value For Concrete Floor. R & u value chart for spancrete hollowcore slabs equipment. A u value is a number that illustrates the rate at which heat is transferred through a structure. The better the insulation quality.
A concrete wall with thickness 0.25 (m) and conductivity 1.7 (w/mk) is used for the default values in the calculator above. It measures the effectiveness of insulation or thermal resistance. Reference table for u values u value is the coefficient of transmission, i.e., the transmission of heat through the materials, which compose the building's envelope, or outer shell.
