Concrete Floor U Value. (cibse guide table a3.1., 1980) While the values do vary for each particular material and method of construction, the following table gives general figures for some common modes of construction. R & u value chart for spancrete hollowcore slabs equipment.
The standard unit of measurement for this is w/m²k. The u value can be calculated as u = 1 / (1 / (5.8 m2k/w) + (0.25 m) / (1.7 w/mk)) That is, how effective they are at preventing heat from transmitting between the inside and the outside of a building.
