4 Big Benefits of 4 Seasons Wollongong Underfloor Insulation
Using only the highest rated insulation materials, you can enjoy the
following advantages when insulating your underfloor with us:

1
Savings on your energy bills
Underfloor insulation minimises the amount of heat lost through your home. As a result, you can maintain ideal temperatures more naturally without having to run your air conditioners and heaters as frequently. This means you may save money on your energy bills while also quickly recovering your initial investment in underfloor insulation.

2
Sound reduction
Sound can enter and move through your home via unsealed floor spaces. If you live in a busy area, polyester underfloor insulation can be helpful in keeping outside noise from coming inside. By blocking these spaces, you can help to reduce the amount of noise that comes into your home.

3
Environmentally sustainable
Underfloor insulation can reduce the running of air conditioners and heaters, which means less energy is used and therefore has a positive impact on the environment by reducing energy demand and emissions. So not only can you make savings, but you’ll be helping the planet too!

Ideal Timber Floors
Air gaps are common in hardwood floors, which allows air to easily pass through. This makes it an extremely poor insulator and may result in you spending a significant sum of money on your energy bills.
With Polyester Underfloor Insulation, you can build a barrier that deflects air from beneath your house and keeps the temperature inside consistent during the summer and winter. As a result, you and your family may be comfy all year round because your home is kept cool in the summer and warm in the winter.

FAQs on Polyester Underfloor Insulation
Does underfloor insulation stop moisture?
Yes. The polyester insulation does not absorb moisture. It is also supplied in long rolls, which means there are less joins and less opportunities for moisture, and of course air, to sneak through.
How long will the underfloor insulation last?
Polyester insulation comes with a 70 year durability warranty when installed in accordance with the manufacturer’s instructions, so you can be confident that it will remain effective for a very long time. The insulation itself is heat bonded, so it doesn’t rely on formaldehyde glues, which can deteriorate over time.
Is underfloor insulation environmentally friendly?
The use of underfloor insulation makes your home much more energy efficient, because it is more thermally efficient so requires less use of air conditioners and heaters. This has a very positive impact on the environment, because it reduces the amount of energy demand and emissions.
How safe is polyester underfloor insulation?
Very! The polyester material has zero ignitability and zero spread of flame. It is also non-allergenic and naturally resistant to insect and vermin attack, without containing chemical deterrents – it’s actually the same product found in your pillows and doonas.
Do I need other types of insulation in my home?
