Make considerable savings on your insulation solution

It’s important to periodically assess if you have enough home insulation and if it’s still being effective:

If you answered yes to any of the above, your home insulation might need a top up.

A top up is a very cost effective way to improve the efficiency of your home, as we can simply add to what you already have without the need to completely remove all your insulation and replace it.

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

Savings on your energy bills

Effective insulation increases the thermal efficiency of your home, so you can maintain desired temperatures more naturally without needing to run your air conditioners and heaters as regularly. As well as making your home more comfortable, this means you can make savings on your energy bills, and quickly recoup your investment for the insulation top up.

Environmentally sustainable

The reduced running of air conditioners and heaters means less energy is being used, which therefore has a positive impact on the environment by reducing energy demand and emissions. So you can save money and the planet all at the same time!

FAQs on Insulation Top Up

  • If you’re willing and able, you can take a look in your roof to see if your insulation has gaps, is at different heights and/or is worn out. If you see any of these issues, you may need a top up.


The best option however is to get one of our experts to come out and give you a free assessment and quote. That way we can give you our expert advice and find a solution that suits you best. To book this in, simply give us a call: 1300 331 336

It may be possible, however we don’t recommend it. The first obvious issue is that a lack of experience climbing around in roof space can increase your risk of injury. Also, while doing it yourself can save money in the short-term it often costs more in the long-run, due to:

  • Sub-optimal coverage, meaning you’ll have to pay for a professional to come in and sort it out
  • Sub-optimal efficiency, meaning you’ll still be spending more than you need to on your energy bills

An insulation specialist knows how to optimise the insulation to ensure full coverage, and therefore full efficiency.

  1. Homes built pre-2000 usually need insulation repair, top-up or removal and reinstallation.

Homeowners with older, poorly installed insulation, and often inferior products, are getting no benefits at all. These older insulation materials may not meet current standards covering the insulation industry, which specify the R-Value requirements in your climate zone. You’ll be amazed by what a difference it makes.

Yes! We offer a workmanship guarantee; ensuring you’re happy, the work is done to a high standard and the insulation is working as efficiently and effectively as possible.

There is also a warranty on all our products (note: this doesn’t cover the existing product that will remain underneath the top up).
