An object of the present invention is to provide a phenol resin foam which suppresses environmental load and has excellent flame retardancy, and can further maintain excellent heat insulation performance for a long period of time, and a method for producing the same.nn n n The present invention discloses a phenol resin foam comprising a phenol resin and a foaming agent containing at least one of a hydrochlorofluoroolefin or a non-hydrochlorofluoroolefin. The phenol resin foam has a density of 10 kg / m 3 to 150 kg / m 3 , a thermal conductivity of 0.0175 W / m‧k under 10 ° C, and a thermal conductivity of 0.0185 under 23 ° C. W / m‧k or less. |
