How is woolcool® made?

British 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 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® boxes do need ice-packs, although the efficiency of the wool liners means they need significantly less than the recommendations for EPS or EPE options with similar volumes

Courier Size 1 - 2 x 250g ice-packs

Is the wool hygienic?

Yes. Through the natural washing and scouring process, the wool is safe enough for a baby to sit on, without any chemicals, additives or the need for further sterilisation. Also, wool does not harbour dangerous chemicals, dust or mould that can lead to allergic or other reactions. The wool is also 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!

Is the wool British?
