A well-insulated floor normally eliminates the need for underfloor heating altogether. Here’s why!

The Retrovive system isn't just another insulation material — it's a smarter, greener, and longer-lasting solution that keeps homes warmer and the planet cooler.

Cellulose-fibre insulation: from mid-19th century to modern-day Passivhaus standards. Using plant fibres as insulation has a long history, but the industrial process of recycling newspaper to make cellulose insulation goes back to the 1950s.

Our cellulose insulation, and the membrane we use in the Retrovive system to hold it in place, are ‘breathable’. This is critical to avoid moisture building up.

Along with great thermal performance, the Retrovive cellulose-fibre insulation system has excellent acoustic properties.
