Building Material Containing Latent Heat Storage Material and Methods of Making the Same

A gypsum board comprising:

• a gypsum core;
• a facing material comprising a first side and second side opposite the first side, the second side is bonded to the gypsum core;
• a layer of encapsulated latent storage material disposed on the first side;
• and
• a coating layer disposed over the layer of encapsulated latent storage material such that substantially no encapsulated latent heat storage material is exposed to an outer surface of the coating layer.

A gypsum board comprising:

• a gypsum core;
• a facing material comprising a first side and second side opposite the first side, the second side is bonded to the second portion of the gypsum core;
• and
• a coating layer disposed on the second side, wherein the coating comprises capsules of latent heat storage material.

A gypsum board comprising:

• a gypsum core;
• a first fiber mat comprising a first side and second side opposite the first side, the second side is bonded to the second portion of the gypsum core;
• a first coating penetrating the first fiber mat from the first side into the fiber mat;
• a second fiber mat comprising a first side and second side opposite the first side, the second side is bonded to the gypsum core;
• a second coating penetrating the second fiber mat from the first side into the fiber mat;
• wherein both the first fiber mat and the second fiber mat each comprise glass fibers nominally about 10 to 16 microns in diameter and about one-quarter (¼) to about one (1) inch in length, the first fiber mat in the absence of coating has a basis weight of 1 to 3 pounds per 100 square feet;
• and
• wherein at least one of the first coating and the second coating each comprise a capsules of latent heat storage material and an organic binder.

A method of making a gypsum board comprising:

• depositing a gypsum slurry for forming a set gypsum core onto a facing material;
• drying the gypsum slurry to form a set gypsum core;
• applying a latent heat storage material on the facing material on a side opposite in contact with set gypsum core;
• and
• applying a coating over the latent heat storage material.

A building material comprising:

• a paneled article having a first side and a second side;
• a layer of encapsulated latent heat storage material disposed on the first side;
• and
• a coating disposed over the layer of encapsulated latent heat storage material.
