摘要

The wall or roof element has between two transparent panels (1, 2) a closed hollow layer (3) which can be filled and emptied of liquid and gas through one or more connections (4, 5) so that the physical properties of the wall elements such as colour, light permeability, resistance to heat radiation, reflection, sound absorption and inherent frequency can all be deliberately controlled within wide range through the choice of gases or liquids.
