~9J:.:..·
I am just briefly writing to alert you to a current danger with regard
to the Insulation Rebate scheme. If there is not a clear mandate in the
instructions for approved fire resistant enclosures to be installed
aro d downlights when insulation is installed, there is a high chance
of fi
. k associated with the installation; due to the likelihood of
verm~n,
bris and loose insulation coming ~ contact with high
temperature parts ie halogen globes, transformers - refer AS3000:2007
4.5 • .2.3.
This scenario is worsened by the fact that downlights are installed on
average one every two square metres and a circular gap of 500mm in
diameter around each downlight would mean that 10% of the average roof
would not be insulated. CSIRO have released figures that say that if
there are 5% gaps in roof insulation, the total R-value of the roof is
reduced by 50t.
James Fricker from the Institution of Engineers has done tests to prove
that a ceiling with R3.S rated batts and 500mm diameter gaps (around one
downlight every four square meters) will be reduced from a total R-value
of 3.78 (including plasterboard) to a total R-value of R2.l6, which is a
loss of Rl.6.2 in total values.
This would effectively mean most homes using the Insulation Rebate would
not reach the stated 2-star energy rating status. This would be a huge
waste of $3.9 billion of tax payers money and owners of newly insulated
homes would not notice any substantial savings on their energy bill.
Downlight guards that are designed to abut insulation, i.e Isolite,
Flexi, etc, will reduce this loss to as little as RO.12 (from R3.88 to
R3.76) . They also prevent airconditioned air from le~king into the roof
space, thereby adding to their energy savings.
It is in the ~est interests of the public for fire resistant downlight
enclosures to be made mandatory in this Insulation Rebate scheme, so as
to be in line with AS3DOO:2007 4.5.2.3.
Appreciate your consideration and look forward to your favourable reply.

I am just briefly writing to alert you to a current danger with regard
to the Insulation Rebate scheme. If there is not a clear mandate in the
instructions for approved fire. resistant enclosures to be installed
around downlights when insulation is installed, there is a high chance
of fire risk associated with the installation, due to the likelihood of
vermin, debris and loose insulation corning in contact with high
temperature parts ie halogen globes, transformers - refer AS3000:2007
4.5.2.3.

there are 5% gaps in roof insulation, the total R-value of the roof is
