Naturally Durable

The wool fibre is a complex structure, with a natural crimp and resilience, or “springiness” that allows it to be stretched as much as one third and then spring back into place. It also possesses tiny outer scales which prevent the fibres sliding past each other. These two unique characteristics assist Terra Lana natural wool insulation to maintain its loft (height) and therefore its ability to entrap air.  Terra Lana natural wool insulation will last as long as your house.
