What Sussmann does

Süssmann AG is a Swiss specialty construction firm founded in 1893 and headquartered in Regensdorf, Switzerland. The company designs, manufactures, and installs acoustic insulation, thermal insulation, and building waterproofing solutions, operating under the SIANG acoustic brand and the Thermo-Plus thermal-insulation brand, with a separate Soniflex e-commerce channel for standardized foam and acoustic products. Its core technology centers on high-density mineral wool, glass wool, aluminum, and fiberglass-mesh composite panels, plus the proprietary type-tested GPB850/1500 soundproof tunnel used in shooting ranges, with products certified under VKF fire-safety, Eco-Bau, MINERGIE, and Eurofins Indoor Air Comfort Gold standards. Its customer base spans shooting ranges and defense (Police cantonale valaisanne, Swiss Army, Club de Tir d'Uzès), industrial noise control (factories such as Landquart), commercial and office buildings, private homeowners, and property managers requiring flat-roof waterproofing.

The firm employs approximately 25 people and is privately held by the Brändli family, with Alex Brändli as Director/Owner since 1998 and Conny Brändli as co-owner since 2009. Revenue is generated through four streams: custom acoustic and thermal insulation installation projects, building waterproofing and flat-roof services, product trading (including in-house manufactured SIANG and Thermo-Plus lines), and sheet-metal (Spenglerei) work. Pricing is split between public unit pricing for standard Thermo-Plus panels (CHF 35-132/m² depending on thickness, with a 2026 price list) and quote-based pricing for custom acoustic solutions and waterproofing projects. The company operates a direct sales-led, field-engineering go-to-market supplemented by the Soniflex online shop, serving primarily Switzerland with recent project execution in France and bilingual (German/French) commercial operations.
