Sandwich type panels are popular building materials with low weight and high strength. Sandwichtype panels nowadays are mostly used in high thickness as elements for external walls or roofs. But in most cases modern building panels contain lots of combustible additives, which can produce toxic fumes and expedite fire in buildings. In this paper, sandwich-type panels are discussed with structural, acoustic, fire and heat insulation properties made of foamed gypsum core with an open and close cellular structure and higher strength lining on both sides made of regular plasterboard. Gypsum is used as a fire protection and acoustical material with excellent fire protection, because it dehydrates at a temperature around 100 ºC absorbing energy and acting as a heat barrier. This research shows that combining desirable properties of gypsum as a high density composition and low density composition can improve the overall material properties and variety of application. It was found that a thinner and lighter composite sandwich panel made of gypsum can resist fire for longer time than rigid gypsum boards with complex structure.
