Since 1974, KE Fibertec AS has developed and produced textile-based ventilation systems in Denmark, replacing conventional steel ducting with lightweight fabric that distributes air softly and evenly. The Vejen-based company combines its own weaving mill with testing and development expertise, and tailors each system to the building rather than keeping standard products in stock. Its work includes Cradle to Cradle-approved ventilation materials and solutions designed for healthier, more sustainable indoor climates.
