INSULWOOL® under normal conditions, will last the life of the house. INSULWOOL® contains a moth-proof to deter vermin attack, a necessity as wool is a food source for a variety of insects.

Wools natural bonding qualities prevent it blowing around in ceilings under normal conditions.

Wool's natural bonding qualities also help it to resist slumpage because, unlike man-made fibres, wool fibres possess outer scales which prevent them sliding through each other and settling.
