Document Type and Number:
Japanese Patent JP2680772
Kind Code:
B2
Abstract:
PURPOSE: To provide an inorganic construction panel which excels in water resistance and anti-moisture property, is lighter than calcium silicate board, and is excellent in the freezing and melting properties.
CONSTITUTION: An inorganic construction panel concerned includes an intermediate, layer interposed between an over-layer and an under--layer as an outer layer part containing a mineral fiber and inorganic powder as major component, where a binder is added and the specific gravity in made no less than 0.8, wherein the intermediate layer chiefly contains an inorganic foaming substance with a binder added to give a specific gravity of no more than 0.4, and they are shaped in a single piece structure in layers having a total specific gravity over 0.55.
