A thermal board including a first layer, a reflective layer a spacing device and a second layer bonded together as a single unitary structure. The spacing device forms a cavity between the first and second layers in which insulation may be positioned. It is contemplated that in one embodiment the first layer is provided as gypsum board and the second layer is a paper material. In another embodiment, a third layer is positioned between the first and second layers, where the third layer is a dense fiber board. Reflective layer(s) is/are provided as thermally reflective layers are provided as, for example, a spray coating and/or a metallic foil acting like a mirror to Infrared Radiation. The thermal board may be provided as a 4′×8′ sheet of material as a single bonded, unitary structure that may be cut and installed in the same manner as standard drywall.
