As a natural product, sheep wool is shorn twice a year and can be returned to the environmental cycle at any time.

Being made from a naturally produced fibre, sheep wool insulation requires less than 15% of the energy required to produce glass fibre insulation. It is a sustainable and renewable resource, that has zero ozone depletion potential and at the end of its useful life can be remanufactured or biodegraded. Sheep wool insulation is safe and easy to handle and no protective clothing or special breathing apparatus is required to install it.
