Sheep wool
The Sheep wool is one of the best natural insulating materials found. The sheep consumes organic carbon that is in the plants and transforms it into wool, sheep are therefore part of the earth’s carbon cycle. The wool is a unique material with complex structure and natural properties. The high insulation value of the wool is due to is physical properties and of the air it forms inside itself. The wool reduces moisture, which means that the wool absorbs moisture up to 35% of its own weight without heat loss and also releases moisture. These feature of the wool acts as a natural temperature control system that maintains constant cold or heat temperature.
Icelandic wool is in many ways unique, but its properties are i.e. how durable and smooth it is that makes the wool a suitable as a insulation material.
By utilizing the sheep’s wool as an insulation for products that require constant temperature during transport time, we multiply the value for companies that rely on constant temperature during transport times and also due to environmental impact.
Research and development
The requirements for better thermal package from environmentally friendly materials have led Cool Wool´s founder to research the possibility of utilising sheep’s wool for use in advanced temperature controlled thermal package.
Since 2016 Cool Wool has been working on environmental friendly thermal package mainly for use in the fish industry. The objectives of this work have been directed towards increasing the insulation value of eco-friendly cooling package. In co-operation with salmon farmers in Iceland, Faroyer and Fraunhofer has led to an active prototype that meets the rules and quality requirements for fresh food delivery.
Developments are aimed at producing cooling boxes that can keep food cold under 4°C for 96 hours. The aim is to design sophisticated solution that take into consideration the entire system and entire life of the cooling boxes all the way back to the nature.
All studies that Cool Wool has undertaken indicate that the insulation value of eco-friendly cooling box made from sheep’s wool and sustainable packaging material maintains the cooling of fresh fish better than conventional thermal boxes on the market today.
