is manufactured in Australia from Cellulose, a superb, natural, thermal insulator, treated with a combination of fire retarding, vermin resisting chemicals.

Insulfluf above your ceiling will act as a thermal shield, making your home up to 10 degrees cooler in summer and up to 12 degrees warmer in winter.

This translates into a massive saving of up to 50% on your fuel bills.

During installation, by use of compressed air, it is funnelled through to the ceiling via a long flexible rubber duct.

The areas between the rafters are filled, blocking gaps and preventing any seepage of heat.


Once installed Insulfluf will not blow around or pack down, thus retaining its thermal insulating qualities indefinitely.

Q: Will Cellulose Fibre put strain on my ceiling?


No it won't, CSIRO testing shows that 10mm and 13 mm plaster board can easily accommodate the 10kg/m2 imposed load while satisfying the deflection limit specified in AS/NZS 2785:2000.


Q: How does Cellulose fibre insulate compared to other products?


Cellulose fibre is a  loose type of insulation which fills every part of your ceiling joist spacings leaving no gaps. Leaving minimal gaps when insulating is crucial for any home, if you have 1% of gaps which is not difficult you lose 10% of the products R rating, 5% you lose 50%.

It doesn't matter how much more you try to compensate by adding more insulation, the problem is the gap is still there.
