Foil insulation - should it be removed?

I have an IP in Queensland that I have only recently purchased. The building inspection identified foil insulation in the roof space. Apparently this was most likely installed during the government roof insulation scheme, and it was common to install foil instead of pink batts in Queensland. The property has safety switches, and no downlights. I have read and been told conflicting information about whether I should have the foil insulation removed. What are everyone's thoughts? And, if it is best to get it removed, what type of tradesperson should I hire?

 

If it were me, and I didn't want to spend money unnecessarily on changing something that probably doesn't need to be changed, to safeguard against liability, litigation and protect your rights re: insurance,

1. Seek clarification in writing from your building insurer and your landlord insurer (also from the liability side for person injury/death etc), if the current state affects your cover in any way.
2. Engage suitable smoke alarm compliance business to handle your smoke alarm compliance obligations, eg. Smoke Alarm Solutions for $79/year etc. so that you did everything right under your Lessor obligations re: smoke alarm legislation for tenancies in Qld.
3. (over kill but for the small cost) Seek clarification from suitably insured building certifier re: the insulation installation in the premise and contraventions of building code/other etc.

Worst case scenario - house burns down, occupants die, coroner comes knocking, you open the door with smoke alarm compliance certificate in one hand, building certifiers report in the other, hands free on your mobile lodging claim with insurer to get your house rebuilt.

 

He suggested removing it, but when I checked with the government insulation website, it said that it can either be removed or a safety switch installed. The property already has a safety switch.

I would prefer to remove it, but have no idea what type of tradesperson does this. Do you remember who removed yours?

 

I wouldn't remove it. The deaths occurred because the foil touched live wires. So the foil wasn't actually the problem, faulty wiring was.
So if you want to reduce the risk of electrocution, the logical thing to do would be to leave the foil in but remove all the wiring.

 

I recall that the wiring wasn’t faulty it was the installation method.

The foil was stapled into electrical wiring using conductive staples - which caused the foil to become electrified.

Best for PO to look up requirements for his/her state.

 

Other than suggesting that I remove it, the building inspector was not very helpful. He did not enter the roof space because of the foil insulation, and did not check if there were staples or faulty wiring etc.

I would really like to remove it so I don't have to worry about anyone's safety, but I don't know who to contact for a quote

 

Your best bet would be to replace the foil insulation with a better product. In Queensland insulation is a necessity.

Left alone, with a safety switch installed, the insulation is probably quite safe. But you will have difficulty if you need any work done, i.e., electrical, that requires access to the ceiling space, as most tradesmen won’t enter with foil insulation in place as existing electrical wiring can’t be seen.

Contact any insulation company and ask for a quote to remove and replace.

Even if that's the case, the foil itself does not present as a risk unless there's any exposed conductors touching it.
If you have RCDs for all your circuits, then the risk becomes extremely low, even if there was an issue.

 

I would be very reluctant to get in the ceiling where there is foil insulation but I don't necessarily think that it needs to be removed.

If power is off at the switchboard it doesn't guarantee there is no power in the ceiling. Even if you have RCDs on all circuits you may still have unprotected power in the ceiling.

 

Most homes wont have RCD switches on lights, fans and downlights which are in roof space. Just on main power point circuits

Covering wiring with foil seems an illogical cheap solution. Is it capable of removal without damage ? eg To install a new fan, add or change wiring eg smoke alarm ?

 

With all this angst, we still don’t know where the foil is installed!

It makes a big difference.

Is it laid over the ceiling on top of the joists?

Or is it under the tiles or corrugated iron roof?

 

I always though sarking under the roof is different to ceiling insulation although I see the similarity. Hot air circulates between the two thought....

 

It's not sarking under the tiles, it is foil insulation laid over the ceiling.
