However the following expression can be used to compute r this equation is provided by astm c 168.

Thermal conductivity of concrete roof slab.

99 4 less than the zinc sheet 72 5 less than the concrete roofing tile and 49 2 less than the ceramic roofing tile. The roof of a house consists of a thick concrete slab of l thickness with thermal conductivity k w m c and area a. A reasonable r value for a normal concrete slab can be estimated using an r value the thermal resistance per inch of thickness between 0 1 and 0 2 and multiplying it times the slab thickness. Calculating the inverse of that 1 r would give you a u factor in the range of 1 67 to 0 83.

The roofing tile made from recycled materials has a lower coefficient of thermal conductivity than the other building elements. Thermal conductivity is a material property that describes ability to conduct heat thermal conductivity can be defined as the quantity of heat transmitted through a unit thickness of a material in a direction normal to a surface of unit area due to a unit temperature gradient under steady state conditions. Cintemac laboratory utn córdoba. If the outer surface of roof stays at steady temperature toor 20 c and the inner surface temperature of concrete is tin 23 c.

4 place of realization. A reasonable r value for a normal concrete slab can be estimated using an r value the thermal resistance per inch of thickness between 0 1 and 0 2 and multiplying it times the slab thickness. The thermal resistance or r value m 2 k w is calculated by dividing the thickness of the material in metres by the k value. For a 6 inch slab r value would be between 0 6 and 1 2.
