A latent heat storage gypsum plate includes: a gypsum plate having a first main face and a second main face located on an opposite side of the gypsum plate from the first main face; and a latent heat storage layer disposed over at least part of the first main face of the gypsum plate and including a latent heat storage material and a binder. A heat storage capacity of the latent heat storage gypsum plate is 260 KJ/mor more, the heat storage capacity being measured in a measurement temperature range of from 15° C. through 35° C. through heat storage capacity measurement specified in ASTM C 1784. The latent heat storage gypsum plate exhibits heat generation property grade 1 as evaluated by a heat generation property test specified in JIS A 6901 (2014), with the face in which the latent heat storage layer is disposed being set as a back face.

Latent heat storage gypsum board and partition structure

The present invention is to provide a gypsum-based load-bearing board for wood structural load-bearing walls which is capable of increasing the co-efficient of effective wall length without additionally using reinforcement materials or stiffening materials, and without increasing the specific gravity and/or the thickness of the gypsum-based load-bearing board. The gypsum-based load-bearing board for wood structural load-bearing walls includes a main member or a core member formed from a board-shaped hardened gypsum containing an inorganic fiber and an organic-based strength enhancer that exert a lateral nail resistance of 500 N or more, and a paper covering at least front and back sides of the main member or the core member to constitute the load-bearing board.
