Why Choose Spray Foam
Transform the performance of your building.
One application can insulate, air seal and help manage moisture, delivering long-term comfort and energy efficiency.
Thermal Performance
Sprayed directly to the substrate, foam helps reduce heating and cooling loads and keeps temperatures more stable.
R1 to R8 depending on system
Seamless Air Sealing
Foam expands into cracks and joins as it's applied, forming a continuous air barrier that batts alone can't provide.
Closed cell seals as it insulates
Moisture Control
Closed cell foam isn't water permeable, making it a strong choice for underfloors, metal roofs and condensation-prone spaces.
Choose the system for the space
Acoustic Comfort
Open cell foam fills cavities in a single application and helps dampen outside and unwanted sound.
Project-dependent acoustic improvement
Performance varies with the product, thickness, building design, climate and installation. Fire performance is product specific: see our fire performance page.

Closed Cell Spray Foam
Made with an ultra-low GWP blowing agent and recycled PET bottles.
Sustainable High Performance
Experience The Spray Foam Difference
We install closed cell and open cell systems from Huntsman Building Solutions, chosen to suit the building. Sprayed in place, the foam adheres to the substrate and fills the gaps that other insulation can leave behind.
- A seamless layer of insulation and air sealing
- Closed cell or open cell, matched to your project
- Installed by Huntsman-approved applicators
Spray foam thickness and R-values
| Foam type | Used in | R-value | Thickness | Best for |
|---|---|---|---|---|
| Closed cell | Underfloors, under slabs | R1.0 | 24mm | Tight spaces and moisture-prone areas |
| Closed cell | Roofs, sheds, workshops, walls | R2.0 | 48mm | Metal roofs and walls, condensation control |
| Closed cell | Commercial, mining, modular | R3.0 | 72mm | Higher thermal targets in shallow framing |
| Closed cell | Roof and ceiling assemblies | R4.0 | 96mm | High performance where depth is limited |
| Open cell | Wall cavities, midfloors | R1.3 | 50mm | Sound dampening between spaces |
| Open cell | Wall cavities, ceilings | R2.6 | 100mm | Filling cavities in one application |
| Open cell | Interior roof and ceiling assemblies | R3.9 | 150mm | Deep cavities, comfort and acoustics |
Indicative values only. These figures must be verified against the current manufacturer data sheets before they're used for design, specification or compliance. They are based on closed cell foam at 0.024 W/mK and open cell foam at R1.3 per 50mm, and products may change over time. Actual performance depends on the product, installed thickness, substrate, climate and building design. We confirm the final system, thickness and any required thermal barrier for each project.

Expert Answers
Frequently Asked Spray Foam Questions
What you need to know about foam types, R-values, where spray foam can go, safety and fire performance.
Have a specific project question?
Our team can talk through your substrate, access, climate and the data sheets you need.
Ask Our Technical TeamWhat is the difference between closed cell and open cell spray foam?
Closed cell foam cures into a hard, rigid layer with a higher R-value per millimetre, and it isn't water permeable. Open cell foam cures soft and flexible, expands to fill cavities and helps dampen sound, but it is water permeable and is used for interior applications. We recommend the right system for your building and climate.
What R-value can spray foam achieve?
We install spray foam from R1 to R8, depending on the product and thickness. As a guide, our closed cell foam reaches R2.08 at 50mm, and our open cell foam reaches R1.3 at 50mm and R3.9 at 150mm. Your climate, the area being insulated and the build type determine the right target.
Where can spray foam insulation be used?
Common areas include underfloors, crawl spaces, roofs, ceilings, walls, under slabs, sheds and workshops. We also insulate commercial buildings, cool rooms, food premises, mining camps, modular buildings, shipping containers, truck bodies, tanks and pipework.
Is spray foam safe once it has cured?
Once cured, the foam is non-hazardous and free of formaldehyde and asbestos. It must be installed by licensed applicators wearing PPE while it is airborne, so occupants stay clear during application and return when the installer advises it is safe.
Is spray foam insulation fire rated?
Spray foam is generally classified as a combustible material under the NCC, and fire performance varies by product and configuration. Some products have been tested to AS1530.3 or classified under AS/NZS 3837, but those results apply only to the tested product and don't by themselves demonstrate fire resistance or NCC compliance. See our fire performance page and ask us for the data sheet for your project.
Can I spray foam my property myself?
We recommend professional installation. Correct mixing, pass thickness and safety controls all affect how the foam performs, and experienced applicators have the equipment and training to get them right.
Can you paint spray foam insulation?
In many projects, yes. Painting can suit branding or interior design schemes, but the right approach depends on the foam and the space. Talk to us before you paint, so the finish suits the product and the area.
How much does spray foam insulation cost?
It depends on the area, the product and the thickness needed to reach your R-value. Contact us for a free, no-obligation quote tailored to your project.
