About Us

30 Years of Experience

In Home Energy Smart Solutions

Cool or Cosy emerged from humble beginnings in 1984 to become South Australia’s leading Energy Solutions provider, and a company recognised for its innovation, customer service and integrity.

As South Australia’s pioneering manufacturer of Cellulose Fibre Insulation, Cool or Cosy showed from its inception that cutting edge innovation is at its core. This coupled with the desire to provide unparralled customer service, soon saw Cool or Cosy dominating the market with its local version of the world recognised form of natural Cellulose Insulation.

Cool or Cosy received National recognition for its Cellulose Insulation with iconic projects such as the Sydney Olympic Stadium and Fox Studios in Sydney. Closer to home the refurbishment of the Adelaide BHP Headquarters in Grenfell Street consisted of over 12,000 square metres of Cellulose Insulation.

Over thirty years later, Cool or Cosy now has over 45,000 customers, an enviable reputation of quality and service, and is currently one of the largest Solar System installers in South Australia with over 7000 systems installed.

Ranked South Australia’s #1 Solar Installer in 2015 and 2017 by SUNWIZ
