Overview
Executive summary
Structural laminated glass fins are engineered vertical support elements consisting of multiple glass layers bonded with polymer interlayers. These fins provide lateral support for glass facades while maintaining transparency. Available in standard thicknesses of 17.52mm (8.76+8.76), 21.52mm (10.76+10.76), 25.52mm (12.76+12.76), 31.52mm (15.76+15.76), and 39.52mm (19.76+19.76), using either PVB or ionoplast (SGP) interlayers for enhanced structural performance.
