Roofs, Ceilings & Walls

A continuous layer across the whole building envelope

Residential Roofs, Ceilings & Walls

Roofs, ceilings and walls are where a building gains and loses much of its heat. Spray foam adheres to framing and substrates, filling irregular cavities and sealing joins.

We recommend closed cell or open cell foam based on the area, the depth available and the R-value you need.

Why choose this solution

  • Thermal comfort

    Sprayed directly to the substrate for continuous insulation, helping keep temperatures stable.

  • Air sealing

    The foam expands into cracks and joins as it's applied, reducing air leakage through the building.

  • Fits complex shapes

    Sprayed in place, foam reaches around framing, services and irregular surfaces.

  • Noise reduction

    Foam can help reduce unwanted sound, depending on the foam type and construction.

Performance varies with the product, thickness, building and installation. Fire performance is product specific: see our fire performance page.

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 Team

What 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.
