High Quality Insulation for Homes
Spray foam insulation creates a high-performance insulation and air-sealing layer across walls, rooflines, underfloors and other suitable areas of a home.
It is an excellent choice for high-performance new builds and can also be installed during renovations or used to improve suitable areas of existing homes.
Planning a new home?

High-quality insulation with lasting benefits
Spray foam insulates and seals the building envelope in one continuous system.
Seals gaps
Spray foam expands around framing and into small gaps, helping prevent drafts and reduce pathways used by dust, pollen and airborne allergens.
Continuous air seal
No conventional fitted insulation seals around framing and irregular shapes as completely as spray foam.
Stays in place
The foam bonds to the surface and does not slump or settle, helping maintain consistent insulation performance.
Insulation value
Spray foam provides a very high insulation value for its thickness, making effective use of the available space. View the foam options.
Life of the building
Spray foam is designed to last for the life of the building.
Comfort and efficiency
Insulation and air sealing work together to support more stable indoor temperatures and lower heating and cooling demand.
Built into the home
Depending on the system and construction, spray foam can be installed to the interior or exterior of the building envelope. Once the build is complete, it continues providing insulation and air sealing.
Residential spray foam applications
Walls
Spray foam for exposed wall framing in new builds and renovations.
Roofs and rooflines
High-performance insulation for suitable ceilings, roof decks and roofline applications.
Underfloors
A continuous insulation layer beneath suitable timber floors.
Slabs and foundations
Closed-cell foam for selected below-slab, foundation and concrete applications.
What can spray foam be applied to?
Closed-cell spray foam can be applied across a wide range of residential construction surfaces.
Timber
Framing, floors, roof decks and other timber surfaces.
Concrete
Concrete walls, slabs, foundations and selected exterior applications.
Concrete block
Block walls and masonry construction.
Steel and metal
Metal framing, roofing and selected building surfaces.
Compacted gravel
Applied over suitable compacted aggregate before a concrete slab is poured.
Irregular surfaces
Shapes, junctions and areas where fitted insulation can leave gaps.
Designed around the way you live
Spray foam can support comfort, airtightness and energy performance across a wide range of residential projects.
Coastal homes
Continuous insulation and air sealing for homes exposed to coastal winds and changing conditions.
High-performance and Passive House projects
High insulation values and air sealing for homes designed around efficient, controlled indoor comfort.
Allergy-conscious homes
Sealing gaps can help reduce the pathways used by outdoor dust, pollen and airborne allergens.
Architectural and complex homes
A continuous insulation system for irregular shapes, mixed substrates and detailed construction.

Choosing your spray foam insulation
Both open-cell and closed-cell systems provide high-quality insulation and air sealing. The product details and R-values are covered on the individual information pages.
Closed-cell foam
Higher R-value per mm
A rigid insulation system with a very high insulation value for its thickness. It can be used for interior and exterior applications and is resistant to moisture.
Open-cell foam
Comfort & sound control
A high-quality, lightweight insulation system for interior walls, rooflines and projects where acoustic performance is also important.
Residential spray foam insulation questions
Can spray foam insulation be used in existing homes?
Yes. Spray foam can be installed in suitable roof spaces, underfloors and other accessible areas. During renovations it can be applied when wall or ceiling cavities are exposed.
How long does spray foam insulation last?
Spray foam is designed to last for the life of the building. It bonds to the surface and does not slump or settle.
What surfaces will spray foam insulation stick to?
Spray foam can be applied to timber, concrete, concrete block, steel, metal and compacted aggregate, along with many irregular building surfaces.
What is the difference between open-cell and closed-cell spray foam?
Closed-cell foam provides more insulation value per millimetre and can be used for interior or exterior applications. Open-cell foam is a lightweight interior insulation system that also provides acoustic benefits.
Does spray foam insulation stop drafts?
Yes. Spray foam expands into gaps and forms a continuous air-sealing layer around framing, junctions and irregular shapes.
Is spray foam suitable for underfloor insulation?
Yes, provided we have at least 700 mm of clearance.
