What isofloc does
isofloc AG is a privately held Swiss manufacturer and solutions provider of cellulose-based insulation materials, operating from its headquarters and production facility in Bütschwil (Toggenburg region). Founded in 1982, the company has spent nearly five decades converting paper fibres on a wood basis into blow-in insulation branded as isofloc Zellulosedämmstoff, with a fire-rated sub-line called easyfloc Protect Brandschutz that has been tested to Swiss and European standards. The core proposition is the dual claim of permanent CO2 storage (with up to 80% of stored CO2 creditable toward a building's CO2 balance) and verified fire protection performance, positioned for Minergie Netto Null and other sustainability-certified projects.
The company's revenue model is a hybrid system sale. It sells cellulose insulation material on a one-time basis, rents and sells proprietary Einblasmaschinen (blow-in machines) for both on-site construction and automated prefabrication lines, and generates recurring service revenue through maintenance, repair, and technical support. A professional services layer — certified applicator training plus architectural and building-physics consultation for architects, specialist planners, and timber construction companies — locks in qualified installers and specification pull-through. Distribution is split between direct consultative B2B sales and a transactional e-commerce shop (shop.isofloc.ch) serving Switzerland.
Go-to-market is sales-led and consultative, targeting three primary business segments: timber construction companies requiring process-safe, reproducible insulation application; architects and specialist planners specifying sustainable, high-performance insulation for green-certified buildings; and an SMB / individual channel reached through the online shop. Marketing relies on a multilingual website (DE/FR/IT/EN), industry events, a downloadable planning handbook, and expert endorsements — most prominently from a Minergie board-member architect. The company self-describes as the Swiss market leader for blow-in insulation materials from renewable raw materials.
