Sheep’s fleeces are naturally washed, scoured and felted to make the insulation material to the required thickness which is then cut into strips and sealed within a recyclable polyethylene industry grade wrap.
Wool fibres are incredibly effective at absorbing moisture from the air which minimises humidity and condensation to maintain stable temperatures. The recyclable industry grade wrap which encloses the wool in Woolcool is micro-perforated to allow the fibres to breathe and create the natural cooling system.
With ice sheets used to maintain the cool temperatures for pharmaceutical goods, the Woolcool insulation has been proven to keep contents between 2°C – 8°C for at least 72 hours.
Woolcool does need ice packs, although the efficiency of the wool liners means they need significantly less than the alternatives. Please contact us to discuss your particular application.
Yes, wool is perfectly safe. The natural washing and scouring process requires no chemicals, additives or further sterilisation. Wool fibres have been scientifically proven to absorb and lock-in bacteria and dangerous chemicals. The wool is sealed within recyclable, industry grade polyethylene wrap to prevent the fibres coming into direct contact with packaged contents.
No. After the natural washing and scouring process, the wool only has a similar smell to a new, pure wool jumper! It is also sealed within recyclable, industry grade polyethylene wrap to prevent contents coming into direct contact with the wool fibres.
This depends on the condition of the Woolcool after use, for example whether it has been ripped or if contents have spilled out or seeped into the insulation. If the Woolcool cannot be re-used as it is, the wool can be recycled and re-used or put to many good uses from lagging pipes to insulating garden plants from the frost!
The wool is sustainable, recyclable, compostable and biodegradable. The polyethylene wrap is recyclable through Soft Plastics NZ and commercial recycling services. Always check with your commercial recycling provider if HDPE soft plastics are accepted at their depot. If the Woolcool cannot be re-used as it is, the wool can be recycled or put to many good uses from lagging pipes to insulating garden plants from the frost or as mulch!
