What Types of Roof Installation
Do We Install?
At 4 Seasons Home Insulation, we offer three prime roof insulation options in Sydney:



Woolcell insulation is a leading insulation product that is environmentally friendly, user friendly and comes with a lifetime warranty:
- Woolcell is a premium pump-in roof insulation product, designed and manufactured in Australia. Woolcell is environmentally and user friendly, using Australian wool, recycled paper, Borax and Boric acid (both of which are naturally occurring salts)
- Woolcell gives you 100% coverage. It is fire retardant (acting as a fire blanket), vermin resistant, and reduces mould (perfect for those with asthma and allergies).
- Woolcell is a combination of wool and mulched newspaper. Wool has been added for the purpose of keeping the product lightweight and ensuring it keeps its “loft” over the lifetime of the structure of the home. It also makes it a “Breathable” product which minimises mould and mildew in the home
Woolcell home insulation was even awarded a National Wool Invention Competition ‘Prize of Distinction’ and is CSIRO-tested for conformance to industry standards.
Our Other Roof Insulation options

Polyester
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
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
