SIGA is leading in the development, production and distribution of products free from residential toxins for the air and windtight building envelopes. SIGA-sealed buildings are characterised by low heating and ventilation costs, higher standard of comfort without drafts and protection from mould.

Know-how, quality, innovation and the consistent striving for sustainability are some of the recipes for the success of the Swiss family business.

SIGA is known for its outstanding tapes, which will seal almost any opening.
