“Lengwil is much more than just a new address for us,” said CEO Matthias Bach at the opening on July 11, 2025. “Here, we are pooling our expertise, creating space for growth, and investing in the future – with regional roots and an international outlook.”
Swisspacer systems improve the thermal insulation of windows and make an important contribution to decarbonizing the building envelope. The following spacer models are manufactured in Lengwil: Swisspacer Ultimate Pro, Ultimate, and Advance.

The portfolio is complemented by Wiener Sprossen and Swisspacer Air, a system that automatically compensates for pressure differences in insulating glass units.
This protects the insulating glass during transport through high altitudes and during installation at high altitudes. The products from the canton of Thurgau are now used in over 90 countries – from single-family home windows to glass facades for skyscrapers.
Part of a strong group
As part of the Saint-Gobain Group, Swisspacer is one of the industry's innovation leaders. The company is committed to digitalization, automation, and the circular economy. This includes its own EPDs (Environmental Product Declarations), a recycling solution for offcuts and rejects, and the use of 100% green electricity in the production process.
The new site in Lengwil was officially opened on July 11, 2025. With the celebration, Swisspacer also thanked all helpers and employees who contributed to the successful new start.

What Swisspacer CEO Matthias Bach has to say
To mark the opening of the new Swisspacer location in Lengwil, GW News interviewed Matthias Bach, CEO of Swisspacer, about regional roots, international goals, and sustainable prospects in the glass industry.

GW News: Mr. Bach, what were the main reasons for moving from Kreuzlingen to Lengwil?
Matthias Bach: We were previously based in Kreuzlingen, so we already had strong roots in the region. By moving to Lengwil, we are deliberately staying in eastern Switzerland, but significantly improving our facilities. It's a real upgrade: for the offices, for production, for our entire team. This shows that we are growing and doing so where our roots lie.
For me personally, it was crucial that we invest not only in buildings but also in the quality of our work. A location must create space – both literally and figuratively. Space for good cooperation, for personal responsibility, for further development. I am convinced that innovation arises where people can get involved. Lengwil is exactly such a place for us.
GW News: What does the new location mean for Swisspacer's positioning in the international market?
Bach: Swisspacer is active in over 90 countries, but we still deliberately focus on strong regional roots. Quality, precision, and reliability are values that are deeply anchored in our Swiss heritage. They shape our products and our processes. The new location enables us to further expand these standards, respond flexibly to customer requests, and produce in a future-proof manner.
GW News: What role does sustainability play at the new location?
Swisspacer
Bach: Sustainability is firmly anchored in our strategy. The building sector is responsible for around 38% of global CO₂ emissions, which means that solutions that contribute to energy efficiency are correspondingly important. Our spacers make an important contribution here. We use 100% electricity from renewable sources, develop recycling solutions for the offcuts from our spacer production for insulating glass, and provide EPDs for all our products. This enables planners and fabricators to make informed decisions. We think about sustainability down to the smallest component.
GW News: Could you say something more about the circular economy? What specific plans do you have in this area?
Bach: Our goal with “www.swisspacer.com” is to create a range of services that helps fabricators return material residues from our spacers back into the production cycle. In doing so, we not only want to help reduce waste, but also actively contribute to resource conservation in the industry. We see the circular economy as a partnership-based function with a clear focus on practical solutions for our customers.
The questions were asked by Matthias Rehberger.
