Glass as a building material appeared 2 000 years ago as an element that closes the openings fulfilling their main function, which is allowing the light to get in the interior of the building. With the development of civil engineering industry and the emergence of the demand that the building should not be just functional but aesthetically acceptable as well, there has been a development of facade elements of buildings, and now there is an increase in the usage of glass panels as cladding on skyscrapers. There are many different systems of glass facade, but all have one and the same element, and it is vertical stiffeners in the form of aluminum, steel or less frequently, glass beams. This paper will examine the glass panels without vertical beams. The aim of this study was to examine six different samples of composite glass and analyze test results. Samples will be tested to collapse in a way that the glass is placed in a horizontal position, supported on the two narrow ends and loaded by applying force to the center of the span to be deployed in-line across the width of the glass. Samples will also be modeled in the computer program Straus7 which calculation is based on the finite element method to display the stress distribution in the glass. With the help of tests the most suitable system of composite glass for production between 6 samples will be determined, or will try to prove the possibility of making glass facade panels without vertical stiffening beams in order to build more economical and aesthetically acceptable construction in the future.
