EPS Cement Sandwich Roof Panel

There are two parts to a roof, its supporting structure and its outer skin, or uppermost weatherproof layer. In a minority of buildings, the outer layer is also a self-supporting structure. The supporting structure of a roof usually comprises beams that are long and of strong, fairly rigid material such as timber, cast iron or steel. Because the purpose of a roof is to protect people and their possessions from climatic elements, the insulation properties of a roof are a consideration in its structure and the choice of roofing material.
