Woolcell insulation is a leading insulation product that is environmentally friendly, user friendly and comes with a lifetime warranty:

Woolcell home insulation was even awarded a National Wool Invention Competition ‘Prize of Distinction’ and is CSIRO-tested for conformance to industry standards.

Polyester Roof Insulation


Polyester insulation is the same material used in pillows and doonas.

The advantages of polyester insulation include:

  • It is excellent for allergy and asthma sufferers since its fibres do not break down into smaller particles, therefore it doesn’t do not produce any dust that can be breathed in
  • It’s itch-free and irritant-free, making it simple and safe to handle
  • Polyester insulation has excellent resistance to vermin, making it an ideal choice for high-risk regions. The smooth, non-absorbent surface of the insulation makes it difficult for pests to establish a foothold, so you won’t find any nasty surprises
  • It is hydrophobic, so doesn’t absorb moisture
  • Has zero spread of flame, so it doesn’t compromise the safety of your home
Fibreglass Roof Insulation


Fibreglass insulation is made from melted glass that is spun into a mat of fibres. Previously, fibreglass insulation was regarded as an itchy and irritant material, however, the materials and chemicals used to make fibreglass batts have improved significantly in the past 5-10 years.

While it isn’t completely itch-proof yet, fibreglass insulation has made significant progress over the previous version and still has certain advantages over other types of insulation.

The advantages of fibreglass insulation include:

  • Fibreglass insulation is a cost effective option, so you can still insulation your home, even if you are on a strict budget
  • It has a zero spread of flame, so it will simply melt and won’t catch on fire
  • We only use Australian-made, high-quality Fibreglass at 4 Seasons, which comes with a 70-year guarantee

This product is perfect for those who are looking for a better alternative to standard fibreglass. Bradford Black Fibreglass is more durable than the older versions and it can be used in a variety of applications.
