Why should we use wool in a van?

Alternatives are toxic garbage. Conversely, there is nothing like a wool fiber.

This answer is both simple and complex. The former is easy – the alternatives are toxic garbage. Conversely, there is nothing like a wool fiber. Nature’s R&D department looks back some 10,000 years. Wool fiber has evolved to protect sheep from the elements – hot and cold; damp and dry. The same goes for your van. Wool inherently manages moisture against 65% relative humidity (see below for more), absorbs harmful chemicals such as formaldehyde, NOx and SO2, crushes road noise and can be reused or composted (to grow award-winning heirloom tomatoes) should you choose to move into a new rig.
