Adding Insulation to Your Home

Unless your home was constructed specifically for energy efficiency, and from experience there are very few that are, you can more than likely reduce your reliance on energy by employing insulation the right way. While older homes have less insulation than homes built recently, it is also important to have newer homes checked as adding insulation can pay for itself easily within a couple years.

Heating and Cooling is responsible for up to 50% of your energy spend. Investing in Insulation will mean a smaller solar system is needed in most situations and obviously drastically reduced energy bills. Or in the case of gas, going off the gas grid entirely.
To determine whether you require insulation a free assessment can be requested with iRenewables where one of our experts will check your existing insulation and give you an honest assessment of your current insulation, what measures can be taken to improve it and the benefits this can create for your family.

We install R4 or R6 Knauf Earthwool totally green Insulation made from recycled Materials like bottles and son; it has absolutely Zero Toxic Polypropylene products. Earthwool Ceiling batts are odourless, rot proof, non-hygroscopic, do not sustain vermin and will not encourage the growth of fungi, mould or bacteria.


The Earthwool® Underfloor roll is a new generation of softer, safer and more environmentally friendly glasswool insulation that has a wind wash barrier to make it even more thermally efficient.

Advanced compression packaging reduces handling time and the storage space required on-site. This work usually needs at least a 450mm crawl space.

Wall Insulation

The Envirowall dry insulation wall cavity insulation process is fully completed from outside the house making it one of the least invasive methods of house wall installation available in not only Melbourne, but Victoria wide. Using specialised machinery, the product is pumped into the cavity space between the internal plasterboard and external facade of the house from the roof cavity.
