What is Woolcool insulation made of?

100% felted sheep’s wool, sealed within recyclable food grade polyethylene wrap.

How is Woolcool made?

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 food-grade wrap.

How does Woolcool keep contents cool?

Wool fibres are incredibly effective at absorbing moisture from the air which minimises humidity and condensation to maintain stable temperatures. The recyclable food grade wrap which encloses the wool in Woolcool is micro-perforated to allow the fibres to breathe and create the natural cooling system.

How long will Woolcool keep things cool?

With ice sheets used to establish the cool temperatures for packaging foodstuffs, the Woolcool insulation has been proven to keep contents packed at 1°c, chilled below 5°c for at least 24 hours.

How many ice-sheets will I need?

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.

Does wool keep products warm?

Yes, wool is excellent at maintaining temperature and has been tested for ambient and warm applications.

Is the wool hygienic?

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, food grade polyethylene wrap to prevent the fibres coming into direct contact with packaged contents.

Does the wool smell or taint foodstuffs?

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, food grade polyethylene wrap to prevent contents coming into direct contact with the wool fibres.

How many times can Woolcool be re-used?

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!

Can Woolcool be recycled?

The wool is sustainable, recyclable, compostable and biodegradable. The food grade wrap is also recyclable.
