Structural Floor Panels SCOPE This design and installation guide for Supercrete Structural Floor Panels is intended for use by designers, architects, engineers, building consents authorities, building owners and panel installers. It details the features and benefits of the panels, where they can be used, how they are incorporated into structures and how to design diaphragm floors and roofs with these panels. Common details are included and these can also be downloaded in CAD, .dwg, .dxf or .pdf format from the website www.supercrete.co.nz for inclusion in construction documentation and specifications. Supercrete Structural Floors and Roofs compliment many Supercrete Block walled buildings, providing compatible movement, shrinkage and seismic behaviour characteristics. The same great thermal, acoustic and fire insulation properties of Supercrete can be applied to walls, roofs and floors. Supercrete Structural Floors and Roofs are only a quarter of the mass of dense concrete, so they are also used in steel or concrete framed buildings, where building mass is a consideration. Lightweight Supercrete Floors and Roofs reduce the size of support members, resulting in savings throughout the structure, compared to dense concrete systems.
