Do you want to cut your electricity bills, keep your home warmer in winter and cooler in summer, reduce greenhouse gases, or protect your precious asset mould? Then you need to think about spray foam insulation.

Making the right choice on home insulation is absolutely essential if you want to enjoy all the benefit of good insulation. And the cost of the insulation that you choose is a big part of that choice. So, let’s take a look at the real cost of spray foam insulation.

The Cost of Spray Foam Insulation

The cost of spray foam insulation varies depending on factors like the type of spray foam, area to cover, R-value required, and labour costs. Some variables will increase the cost of your project and others will decrease it, but we’ll get into that shortly.

The cost of installing insulation to under floors or ceiling areas is around $35/m2 and from $45/m2 for walls here in Australia (difficulty of installation determines the cost).

Here’s a quick look at how much you can expect to pay to insulate a ceiling or floor depending on what kind of home you have.
