Hollow brick for building outside walls - has thin outer layer joined by webs to inner load-bearing layer

摘要

The pressure resistant heat and noise insulating hollow brick is used for making external walls. The brick may be filled with insulation material. The outside layer of the brick is kept as thin as possible, and has a number of holes and staggered webs. The inner part which carries the load is much thicker and has smaller holes and higher material density and acts as heat storage and noise insulation.
