Exfoliated Vermiculite is well established as an excellent thermal insulating material capable of withstanding temperatures in excess of 1000°C. The free flowing properties of loose-fill Vermiculite make installation very simple in applications such as loft insulation.      The insulating properties of Vermiculite significantly reduce the loss of heat in cold weather and keep the interior cool in hot weather. Vermiculite is clean to handle, non-abrasive, sound absorbent, resistant to decay, odourless and non-irritant.
