A fireproof covered structure for covering a penetration part formed in a fireproof beam of a wooden building to make the penetration part fireproof, wherein a tubular fireproof covering material is attached to the penetration part while covering an inner peripheral surface of the penetration part. The tubular fireproof covering material is formed by stacking a plurality of gypsum board pieces cut out from commercially available gypsum boards of thicknesses of 9.5 mm to 25.5 mm, in the thickness direction and unitarily connecting the gypsum board pieces. The tubular fireproof covering material is inserted into and attached to the penetration part such that a connecting portion That connects gypsum board pieces That are adjacent in the stacking direction is disposed at a boundary portion between a structural member and a covering member of the fireproof beam, or at a portion close to the boundary portion.

A wall assembly is manufactured for supporting an exterior covering of a structure. The wall assembly includes a frame assembly including a top member and a bottom member spaced from the top member. The frame assembly further includes a plurality of vertical members spaced from each other and coupled to and extending between the top and bottom members. The plurality of vertical members each have an exterior surface configured to face an exterior of the structure. A rigid foam layer is directly coupled to the exterior surface of the plurality of vertical members. A sheathing layer is coupled to the rigid foam layer opposite the plurality of vertical members with the sheathing layer configured to receive the exterior covering.
