Loose Fill Asbestos Insulation

Asbestos loft insulation

You can find Loose fill asbestos in lofts as loft insulation, but it can also be found under floorboards an inside cavity walls, both in domestic and commercial properties.

It’s very easy to identify as it has a fluffy, almost candy floss-like appearance, usually white or blueish grey.

Out of all the asbestos containing materials you may come across, loose fill asbestos is probably the most dangerous you would find in a domestic property.

Asbestos loft insulation is pure asbestos fibres, so if breathed in will cause the most damage to health.

For this very reason, you should never attempt to remove this type of asbestos yourself.

Always use a licensed asbestos removal contractor to remove and dispose of loose-fill asbestos insulation safely.

Vermiculite Insulation

Vermiculite loft insulation is a naturally occurring mineral that is perfectly safe when pure. Vermiculite is a silver-gold to a grey-brown mineral that is flat and shiny in its natural state.

When heated to around 1000 degrees C, it pops (or puffs up), creating pockets of air. This expanded form, and the fact that vermiculite does not burn, made the material suitable for use as loft insulation.

Vermiculite produced by the Libby, Montana, asbestos mine can contain asbestos.

We do not recommend you take samples of the loft insulation. You need a person who has had the appropriate training.

If the sample contains asbestos, you will need to minimize asbestos exposure from vermiculite.

Do not remove or disturb the loft insulation. If you move the vermiculite, it will cause fibres to become airborne.

The following precautions will prevent releasing asbestos fibres into the air:

  1. Do not use the attic for storage.
  2. Nobody should go into the attic.
  3. Never remove the insulation yourself.
  4. Seal all cracks and holes in the ceilings to prevent insulation from falling out.
