SIGA is leading in the development, production and distribution of products free from residential toxins for the air and windtight building envelope. SIGA-sealed buildings are characterised by low energy consumption and CO₂emission, high living comfort and durability. Know-how, quality, innovation and consistent striving for sustainability are some of the recipes for the success of the Swiss family business. The brothers Reto and Marco Sieber carry on the business in the second generation.

Today SIGA has 300 employees in Schachen and Ruswil in the Canton Lucerne (Central Switzerland) and in the sales organisations in Germany, Austria and Switzerland. But also in the rest of Europe our sales organisation is continuously expanding. SIGA is operating for example also in Ireland, France, Luxembourg and Norway. Further countries will follow, because the demand for the high-quality SIGA products is continuously increasing.

Quality: One of our recipes for success is the perfect and constant quality of our products. By extensive quality controls we ensure that you always receive first-class products.

Environmental protection: We at SIGA deal carefully with the natural resources. Since we manufacture our products ourselves, we can state in good conscience that all production processes are environmentally friendly and that our products are ecologically harmless. We use rain water instead of drinking water and make use of heat recovery. Our products contribute significantly to the reduction of the worldwide energy consumption and CO₂ emission. In addition, investment in a biogas power plant and installation of a solar power system are planned for the future.
Also in daily office life small measures have a big impact; e.g. our computers are connected to toggle switches, the lighting in the aisles is controlled by motion detectors, etc.

Health protection: For the manufacture of our products we never use any harmful raw materials. We thoroughly ensure that our products are free from residential toxins, such as solvents, high boilers, formaldehyde, chlorine and plasticizers.

Innovation / Further development: SIGA is the embodiment of Innovation in the market. We are continuously developing to meet always the state-of-the-art standards of technology and ecology. Processes and products are regularly checked and optimised to enable us to respond to our customers' requirements even better and always be one step ahead for your benefit.

Mutual appreciation / Fairness: We are open-minded and treat each other with respect. A good working atmosphere and constructive human relations are important to us.

Flexibility: The market does not stand still. And we also do not rest on long-established habits. Processes and products are regularly checked and optimised to enable us to respond to our customers' requirements even better.

Social responsibility: Being a successful enterprise we also are aware of our social responsibility. Education and the chance for a better life are no matter of course for needy children. That is why we have supported the "San Francisco” school in Santa Teresa, Nicaragua, for many years.
