The housing industry is a critical component of the American economy representing about 4% of the economic activity of the nation. Light weight structural insulated panels (SIP) for walls and roofs are gaining wide acceptance in the construction industry because of the advantages they offer. Energy savings, sound abatement, disaster resistance and durability are just a few of the benefits of buildings constructed with SIP. A variation of these panels is a structural concrete insulated panel (SCIP), commercially referred to as the MetRock (MR) Panel system. The aim of this paper was to study the flexural behavior of the SCIP system and discuss the manufacturing and construction aspects of the SCIP system. An analytical method for estimating the panel’s flexural strength was developed and a step-by-step design procedure is provided to predict the load carrying capacity of the panels and provide the engineer with a reliable tool for designing the panels. An experimental program was conducted and the results were compared to the analytical method for different size panels. The test results were in close agreement with the estimated values thus verifying the validity of the analytical approach.
