Thermal insulation tile has thermal conductivity of no more than 0.27 W(m-K), preferably no more than 0.26 W(m-K) and no less than 0.22 W(m-K), preferably no less than 0.24 W(m-K)

摘要

The thermal insulation tile (1) consists of a fired tile material with a number of vertical holes (2) and at least two butting surfaces (3,4) with teeth. The fired tile material has a thermal conductivity of no more than 0.27 W(m-K), preferably no more than 0.26 W(m-K) and a thermal conductivity of no less than 0.22 W(m-K), preferably no less than 0.24 W(m-K). An independent claim is also included an unfired semifinished product for an inventive device.
