Vermiculite Fill Insulation

Today we will be looking at Vermiculite Fill Insulation; what it is and what advantages it has to offer.

Instead of the more common fibreglass blanket loose fill vermiculite loft insulation can be used to insulate your roof space.

This type of loft insulation is growing in popularity as it is not only very easy to use but, because vermiculite is a completely natural product, it is much more environmentally friendly than traditional insulating methods.

Whereas the usual blanket insulation is supplied and fitted in rolls vermiculite loft insulation comes in bags or sacks which are simply emptied and raked into the gaps between the joists and the ceiling / loft floor.

So What Is Vermiculite?

It is a natural material of thin flakes which are very light and which also contain traces of water. When exposed to heat, i.e., when heat rises into the loft, the flakes expand to provide very effective and high quality loft insulation.

And, best of all for those of us who are fed up with the irritating skin rashes when using fibreglass blankets, vermiculite loft insulation does not irritate when touched and is fibre-free.

Vermiculite loft insulation is also odourless, clean and easy-to-handle. The material is very effective at stopping heat loss and, in warmer temperatures, is also a coolant.
