The unique insulation in woolcool® is produced using pure wool from British sheep, an innovative use of a truly natural resource.
Totally sustainable, wool is one of the most abundant under used, renewable resources on our planet - we plan to change this.
Our wool is sourced and processed specifically for woolcool®: This means it doesn't contain the additives found in other types of wool insulation such as borate or polyester - simply pure clean wool, safe and fully compostable. The original, four years of development, trials & testing have enabled The Wool Packaging Company to understand and optimise the superior, natural insulative and protective properties of wool fibres. Woolcools® superior insulative results are due to the natural properties of the wool fibres themselves. Like other insulation materials,woolcool® fleece liners work on the principle of trapping still air to reduce the rate of heat transfer. woolcool® takes this a huge step further - the wool fibres actually "works" controlling the moisture content in the box,keeping the goods cold for longer. Wool fibres are hygroscopic (absorb and release of air borne water molecules)- wool can hold up to 35% of its own weight as moisture. This controls the humidity in the box, creating a natural cooling effect. A further benefit, is that this significantly reduces condensation build up in the box, which with other boxes can result in the goods sitting in puddles of water. Wool fibres have many overlapping scales which make them extremely flexible and create a memory-effect,after significant compression, wool will return to its original shape. Naturally fire retardant,insulation wool reduces health and safety risks in event of a fire. ;
