Abstract

Un panneau mural comprend une plaque décorative sur des côtés opposés et un encastrement encastré autour des bords. Du béton à faible densité remplit le cadre entre les plaques. Par conséquent, un mur peut être construit en mettant en place des rails et/ou des goujons, puis en faisant coulisser des panneaux sur les rails et/ou les goujons. Les plaques chevauchent les rails et/ou les goujons. Le panneau correspond à toute la hauteur d'une pièce standard avec une section supérieure non remplie qui peut être découpée à la bonne dimension pour s'adapter à des plafonds plus bas.
