Why Retrovive is the future of sustainable underfloor insulation
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.


Retrovive and Passivhaus
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.


Breathable membranes and moisture control
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.


The sound-absorbing benefits of underfloor insulation
Along with great thermal performance, the Retrovive cellulose-fibre insulation system has excellent acoustic properties.


Thermal performance of Retrovive cellulose insulation
The Retrovive system, meets the latest UK building regulations performance requirements and eliminates draughts for additional comfort
