Tradition
For 50 years, we have developed and produced, with great experience, high performance nontoxic adhesives, tapes and membranes. In 1966, Paul and Trudy Sieber-Gadient established SIGA. In 1990 the two sons, Reto and Marco Sieber, took over and grew SIGA from 15 to 400 employees, and soon the third generation will be ready. In 2013, SIGA was presented with the Family Business Award, making it one of the most enduring family businesses in Switzerland.
