Furthermore, since thecement layer 102 has a hard surface and is not easy to wear out, and it also has features of nice moisture proofing, mould and fungus proofing, erode proofing, fireproofing, and free of deformation, and therefore the building board of the present invention is more durable compared with conventional building boards using wooden material. - In practical applications, the capability of moisture proofing and anti-deformation of the building board changes with the thickness of the
cement layer 102 and themagnesium oxide layer 104. In a specific embodiment, thecement layer 102 has a thickness from 2 to 20 millimeters. In another embodiment, themagnesium oxide layer 104 has a thickness from 8 to 15 millimeters. Such configuration in thickness ensures that the building board has perfect performance of anti-deformation and soundproofing. Moreover, since wood which is currently used with huge consumption has been substituted by thecement layer 102 and themagnesium oxide layer 104, the building board of the present invention reduces the influence on the natural environment with cheaper manufacturing costs. - Preferably, the building board of the present invention can further comprise a heating device. For example, the heating device is configured outside the
magnesium oxide 104. Since heat coming from the heating device can spread easily and fast through themagnesium oxide layer 104 and up into the room, and themagnesium oxide layer 104 can also keep warm longer, themagnesium oxide layer 104 is better for floor heating -
