To provide a fireproof and soundproof panel having a polyurethane foam excellent in soundproofness and fire resistance. A fireproof and soundproof panel is formed by laminating a fireproof soundproof layer formed by molding a urethane resin composition containing a flame retardant and an exterior material. The urethane resin composition containing the flame retardant contains a urethane resin, The weight average molecular weight of the polyol compound contained in the urethane resin is in the range of 1,000 to 20,000, The flame retardant is at least one of red phosphorus and a phosphate containing flame retardant, At least one of the red phosphorus- and phosphate-containing flame retardants is in the range of 0.1 parts by weight to 60 parts by weight with respect to 100 parts by weight of the urethane resin. Fireproof soundproof panel. [Selected figure] Figure 1 |
