Sydney Roof Installation Solutions

in simple terms

At 4 Seasons Home Insulation we have four options for your roof insulation.

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 this material include:

  • Great for allergy and asthma sufferers, as its fibres do not break down into small particles, so it doesn’t emit any dust that can be inhaled
  • Itch-free and irritant-free, so it’s easy and safe to handle
  • Doesn’t attract vermin, 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 up of melted glass spun into a mat of fibres. For many years fibreglass has been 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. So whilst it’s still not completely itch-proof, it’s much better than the older version. 

The advantages of fibreglass insulation include:

  • Cost effective option, so you can still insulate your home even if you’re on a strict budget
  • Has a zero spread of flame, so it will simply melt and won’t catch on fire
  • At 4 Seasons we only use Australian-made, high quality Fibreglass, which comes with a 70 year warranty

Bradford Black Fibreglass

This is a newer version to standard Fibreglass and is more user friendly than its older version.

What makes Bradford Black different?

  • Uses recycled glass and natural organic binders
  • Soft to touch and low itch
  • Made with renewable raw materials
  • 70 year warranty
  • Hypoallergenic properties and low odour (compared to standard Fibreglass)
  • Australian made

Professional installation is the key to any batt solution otherwise the thermal/performance rating will decrease dramatically.


As well as full roof insulation, there are additional accessories you can install to further optimise the total insulation of your home:

  • Tenmat Downlight Covers improve insulation efficiency and safety, as well as minimising gaps in the insulation. Gaps of 5% (including the clearance around downlights) lowers the R-rating by up to 50%
  • A Draft Stopper exhaust fan cover further improves insulation efficiency by eliminating air loss in winter and hot air gain in summer

The use of roof insulation makes your home much more energy efficient, because it is more thermally efficient so requires less use of air conditioners and heaters. Also, the materials used to make some of our insulation options are environmentally sustainable.

Very! Woolcell acts as a fire blanket by smouldering out the flame. Polyester and Fibreglass have a zero spread of flame but they will melt. Woolcell and Polyester insulation are the better choices in terms of itch-resistance and irritant-resistance.
