Abstract
Plate-shaped fire-resistant elements in a sandwich construction have at least three layers connected with one another and resist fire from a front and a back side. The fire-resistant elements are intended in particular for a ceiling or a wall of a building. The elements have a light weight, a high mechanical stability, and can be easily and inexpensively manufactured and installed in a building. The fire-resistant elements have two outer layers and a center layer lying therebetween in the form of a plate, whereby the edge area of the two outer layers is enclosed on at least two oppositely lying sides. Each side has an edge section and the layers are connected with one another. The outer layers have expandable glass granulate or perlite, and the center layer is constructed to prevent passage or penetration of gases.
