Underfloor Insulation Wollongong

Increase the efficiency of your Wollongong home

Make real savings on your home’s heating and cooling costs with underfloor insulation

Your floors run throughout your entire home, which means if they’re not insulated well there are a lot of opportunities for the unwanted heat and cold to get in.

We offer everything you need for underfloor insulation in Dapto, Shellharbour, down to Kiama, and beyond. Our experience and high-quality materials give us an edge when it comes to providing insulation in the Great Wollongong region.

Underfloor insulation creates a barrier that protects your home from the airflow beneath your property, so your home becomes much more thermally efficient. This means you can better maintain temperatures naturally, without needing to run your air conditioners and heaters for as long.

4 Seasons install the most efficient insulation in new and existing floors, with the benefits being almost instant. Not only will you make savings on your energy costs, but underfloor insulation can completely transform the comfort of your entire home! 

We advise home owners, designers and builders on the best approach for any property they’re looking to improve.

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.

FAQs on Polyester Underfloor Insulation

Yes. The polyester insulation does not retain moisture. It is also supplied in long rolls, which means that were are less joins and fewer opportunities for moisture and air to leak through. This is important because moisture and air leakage can lead to decreased energy efficiency in your home.

Polyester insulation comes with a 70-year durability warranty when it is installed in accordance with the manufacturer’s instructions, so you can be confident that it will remain effective for a long period of time. The insulation is heat bonded, so it does not use formaldehyde glues which can deteriorate over time.

The use of underfloor insulation improves the energy efficiency of your home by lowering the amount of air required and producing fewer emissions. It is more thermally efficient, thus requiring less usage of air conditioners and heaters, which has a huge environmental benefit since it reduces energy demand and emissions.

Very! The polyester insulation is extremely safe. The material is composed of recycled materials and is 100% recyclable. It gives off no harmful gases and supports the growth of mould or mildew. There’s nothing combustible about the material, as it contains no ignition qualities and has zero spread of flame. It’s also naturally insect- and vermin-resistant without the use of toxic pesticides – it’s actually the same product found in your pillows and doonas.

We always recommend having complementary insulation throughout your home, and can always provide a quote on how best to achieve this. It is possible to reduce your heating and cooling costs further when you also install complementary ceiling and wall insulation in your home.

Absolutely! Underfloor insulation can be put into existing floors, but there are certain things to consider.
