Insulation Fires

The MFB has responded to several roof fires over recent years caused by electrical equipment in contact with combustible material. In some cases this material has been incorrectly installed insulation.

Down lights, when correctly installed in accordance with the relevant Wiring Rules, DO NOT pose a problem. Insulation, whether it is the “blow in” type or batts when correctly installed, DOES NOT pose a problem.

However, when insulation material is installed directly over downlights or other electrical equipment such as exhaust fans, central heating units, etc.., the risk of fire is greatly increased.

Australian Standards advise that insulation is to be kept clear of downlights for a minimum distance of 200mm all round.

We advise homeowners to:

• Always use a registered and qualified contractor to install insulation in the home.
• Ask the installer to check and confirm that correct barriers are fitted to downlights before placing insulation in the roof space.Never allow the insulation to be placed on top of downlights or other electrical equipment.
• Ensure a registered and qualified contractor confirms that all electrical appliances installed in the roof space, such as down lights and transformers, to ensure that they have either a non flammable/mechanical barrier around them to prevent insulation or other material covering them or the required clearance. A good rule of thumb is a clearance of a hand span’s width is the minimum clearance requirement.
• Where possible, always use the best quality fittings and guards available.
• Following ANY maintenance or works in the roof space, ensure that all downlights, transformers and all other electrical and/or gas appliances are clear of insulation or any other materials.
