Company name

In order to better serve you, Tschopp-Zwissig SA is reorganizing and strengthening its financial structure. For more than 78 years Tschopp-Zwissig AG has been a guarantee of quality and a reference in the world of carpentry and windows.

Known as "TZ" we wanted to rejuvenate and simplify our company name by naming it: tz groupe SA. through this new structure, we continue our activity of interior and exterior carpentry.

A new entity, tz carpentry SA, takes over all our staff and offers quality interior and exterior joinery products, while the existing company Tschopp-Zwissig SA continues to exist and becomes a real estate company. Its VAT number remains unchanged. tz carpentry SA will, therefore, be your privileged contact for the design and implementation of your projects and for any technical advice. Our address, telephone numbers, website, and email addresses remain unchanged. Please note the new VAT number CHE-268.082.082.710. All contracts, receivables, and invoices in progress on behalf of Tschopp-Zwissig SA have been taken over by tz carpentry SA

This change took effect on 20.12.2017. tz remains a family and independent group, proud of its past and looking to the future.
