Vermiculite 4"

Vermiculite gives perfect coverage of insulation in difficult to reach places as well as an easy to manage level fill. Micafil is typically used for chimney flue linings.
Features and Benefits:
Vermiculite is irritant free, ultra lightweight, non-toxic, odour free and fire proof up to 1300 degrees centigrade
Vermiculite significantly reduces the loss of heat in cold weather and keeps the interior cool in hot weather
Vermiculite is a naturally occurring mineral - primarily a combination of silicon, magnesium and aluminium, it is easy to handle, sound absorbent, resistant to decay, fire-resistant and fibre-free
The free running properties of Vermiculite make it simple to install. Poured straight from the bag, it simply flows into and over all potential heat loss areas.
