Where l is the thermal conductivity of a porous ceramic body l o is the thermal conductivity of a porous free ceramic body p is the volume fraction of porous and n is a constant.
Thermal conductivity of ceramic floor tiles.
Thermal conductivity of ceramic and porcelain underfloor heating takes the natural cold out of tiled floors leading to a cozier more comfortable room.
On the other hand the thermal conductivity of ceramic tiles ranges from 0 6 to 1 7 wm 1 k 1 and correlates more with density porosity and less with moisture content 7.
Due to the.
Floor tile materials studied in this work presented a wide range of thermal conductivities framed by the low thermal conductivity of vinyl below 0 20 w m 1 k 1 and the upper limit of granite 4 w m 1 k 1.
The theoretical values determined on the basis of total porosity by astm c329.
Thermal conductivity measurement was conducted according to iso 8301 1991.
In all the samples the experimental values of thermal conductivity are always lower than the theoretical ones and are coherent with the value of thermal conductivity reported in the standard uni en iso 10456 for ceramic tiles with density of 2 3 g cm 3 1 3 w m k.
For this test considering the homogeneous sample it is possible to determine the thermal conductivity through the equation 1 where λ is the conductivity w m k.
Both ceramic and porcelain tiled floors have a high level of thermal conductivity which means when used with an underfloor heating system they heat up faster and retain this heat for longer.
