Why do some people say that clay brick insulation effect is good, and some people say that bad, in the end what is right?
The heat preservation effect should be taken away from the heat insulation capacity of the material. The ordinary clay brick has small heat capacity and slow heat conduction, so it is more thermal insulation.
Now is the best thermal insulation hollow powder briquette, because it is hollow, blocking the heat transfer, plus foam insulation on the outside, good insulation effect,
