SupaSoft Recycled Plastic bottle insulation
A soft-touch loft insulation that’s safe and easy to install

The makers of Thermafleece have turned duvet and pillow technology into safe, sustainable and cost effective insulation for your loft.

Most of us are familiar with the warmth and comfort provided by polyester fibres, widely used to fill jackets, duvets and pillows. Now Eden Renewable Innovations has taken this technology and using recycled polyester fibres made from recycled plastic bottles they have created long lasting and safe insulation for lofts.

Supasoft recycled plastic insulation contains no harmful chemicals or binders and is completely safe to handle. Converting plastic bottles into insulation helps divert many tonnes of waste plastic from landfill or incineration helping protect our environment.

SupaSoft is long-lasting and easy to install. What’s more, energy savings mean the insulation pays for itself in just a few years. SupaSoft can be used to insulate between and over joists or simply laid on top of existing insulation to improve overall insulation performance.
