Insulation

Insulation R-value: The R value is a measure of a material’s resistance to heat flow. The higher the R value, the greater the insulating effect, resulting in improved thermal comfort. Enviroflex staff can visit your home and assess the existing amount of insulation. They can install in homes without insulation or top up existing insulation.  To meet the minimum roof insulation requirements of the National Construction Code, batts are typically installed to achieve an R-value of R4.1. For the Greater Melbourne climate, it is considered better practice to install insulation to achieve an R-value of R5, where space and any other constraints permit. 

As an example, a typical home in Hume could have 130 sq m of ceiling space to be insulated. For an uninsulated ceiling, the base price to supply and install insulation up to R4.1 would be $2,660 (without concession) or $1,860 (with concession rebate), plus any additional costs specific to your circumstances (e.g. Ease of access, any impediments to carrying out the works, an electrical inspection for a Certificate of Electrical Safety and/or removal of existing insulation where necessary). 

As a guide to the area of ceiling to be insulated, your home’s floor plan document may include floor area (sq m). 

* Hume regular price: Prices in the table are based on standard installations of insulation – the final cost of your installation will be provided in a free, no obligation quote. The final cost depends on your specific circumstances, such as an electrical inspection for a Certificate of Electrical Safety and/or removal of existing insulation where necessary.

Note that all insulation jobs through the program require a current Certificate of Electrical Safety. You may choose to have Enviroflex’s electrician provide the certificate (at a cost of $330 inc GST) or arrange one through a suitably qualified electrician.

Note: there are currently no Victorian Government rebates available for insulation.

** Hume concession price: Hume City Council offers the following rebate to eligible concession card holding homeowners who choose to have ceiling insulation installed through the Home Energy Upgrades program: 

• $800 rebate for the whole ceiling insulation job, based on a minimum total job cost of $900. (The concession homeowner pays at least $100). Rebate applies whether insulation is being topped up or installed in a ceiling without insulation.
• No rebates apply for wall or underfloor insulation.
