Flash Line

A flash of inspiration with over 25 years of innovation and sustainable thinking included. Flash Line is created using a combination of speciality yarns, a microtuft construction and the carbon negative materials in our new CQuestBioX backing. This creates a carbon negative carpet tile (cradle-to-gate). Representing a giant leap in Interfacess pursuit to a more sustainable future. Designed with flashes of colours and clean lines. Flash Line uses a speciality yarn that allows the colour flash to appear and disappear. Creating a floor that's simple yet playful.
