PURPOSE: A finishing material for construction is provided to prevent inter-story noise if being constructed as the floor material of an apartment, since shock or vibration can be absorbed. CONSTITUTION: A finishing material for construction comprises a deck(100), a groove(101), and stiffener(20). The groove is formed so that both ends of the groove are opened at the lower part of the deck in a length direction. The stiffener is formed for a metallic material and supports the deck in the groove. |
