An exterior sheathing cementitious panel which prevents water penetration and air leakage is provided. Methods for manufacturing exterior sheathing cementitious panels with a highly efficient integrated air/water barrier sheet are also provided. An exterior sheathing system employing the exterior sheathing cementitious panel is provided.

Water barrier exterior sheathing panel

A heating system for a floor is provided and includes a plurality of heating devices, where each of the heating devices includes a membrane, and a plurality of heating elements and at least one electrical coupling member attached to the membrane. At least one heating device coupling member is attached to the at least one electrical coupling member on adjacent heating devices of the plurality of heating devices, where the at least one heating device coupling member conveys electricity between the adjacent heating devices.

Sectionable floor heating system

A heating device for a floor includes a membrane, a plurality of heating elements attached to the membrane, at least one positively charged electrode attached to each of the heating elements and at least one negatively charged electrode attached to each of the heating elements, where the at least one positively charged electrode and the at least one negatively charged electrode are connected to an electrical power source and supply electrical power to the heating elements. The heating elements, the at least one positively charged electrode and the at least one negatively charged electrode are arranged on the membrane so that cutting of the membrane along a cutting line in any direction across the membrane does not disrupt the supply of electrical power to the heating elements.

A vacuum insulated panel (VIP) and a method of manufacturing a VIP includes a rigid core material having high insulation and low conductivity properties. The rigid core may be made of an inorganic material that effectively mimics a porous silica core material. The core material includes large particles of an inorganic material having a diameter in a range of 10 &#x3bc;m to 50 &#x3bc;m. A portion of these large particles may be ground into small particles having a diameter of less than 1 &#x3bc;m. The small particles are mixed with a portion of the large particles to form a core material which is then mixed with a fiber skeleton and compacted under vacuum along with a fibrous skeleton for structure. The resulting structure provides a porosity ranging from 10 nm to 1 &#x3bc;m in diameter.
