Why Use Spray Foam Insulation?

We understand your requirements and customise your project with you.

Here are just some of the benefits of spray foam insulation applied by Gavin and his specialist team at Australian Spray Foam Insulation:

Green Solution

Polyurethane foam installed by Australian Spray Foam Insulation delivers high-performance solutions for efficient building envelopes, thermal comfort and a healthy living environment.

Choose Australian Spray Foam Insulation — the specialists in draft-free, dust-free, quiet homes and buildings.


Save Energy

You can reduce your heating and cooling by as much as 50%, with a total reduction of heating and air conditioning tonnage by as much as 40% without the loss of efficiency or comfort. 

What’s more, spray foam will not sag or pack down over time and it doesn’t absorb moisture, which are some of the common causes of lost insulation efficiency.

Enjoy year-round thermal comfort in your home or office with Australian Spray Foam Insulation.


Better than Batts!

With a greater R-value than fibreglass batts and other forms of insulations (per thickness), rigid Polyurethane insulation has greater insulating power with the lowest weight and highest insulation value of any common building material.

Australian Spray Foam Insulation fills gaps, seals against draughts and eliminates typical thermal losses via fasteners and structural members.


Allergy Friendly

Dust-free: Structures using spray foam insulation show remarkable reduction of dust accumulation.
Better air quality: Overall reduction of symptoms caused by allergies.

Australian Spray Foam Insulation is CFC free and odour free (once cured).


It was no easy task, but your “can do” attitude was fantastic.

By insulating the floor, the walls and the roof, the home now is extremely comfortable. There are no drafts, which has dramatically reduced our energy bill. Even on 40 celcius summer days, the indoor temperature is easily maintained in the low 20’s without need for air conditioning.
