NZ Foam insulation for your new home
Uneven temperatures, persistent drafts, and rising energy costs are often signs of underperforming insulation. Traditional insulation systems can leave gaps and unsealed areas throughout the home, allowing heat to escape in winter and unwanted heat to enter during summer.
NZ Foam Insulation expands to fill hard-to-reach spaces and create a continuous air seal within the building envelope. Reducing uncontrolled airflow and improving thermal efficiency, it helps maintain a more consistent indoor temperature throughout the year.
The result is a home that stays warmer in winter, cooler in summer, and more energy efficient in every season — with reduced heat loss, lower strain on heating and cooling systems, and improved overall comfort.
NZ Foam insulation can be used in all areas of a home and adheres to a wide range of material surfaces

Residential FAQs
Spray foam insulation combines thermal insulation and air sealing in one application. It expands around framing, services and difficult junctions, helping reduce gaps, draughts and uncontrolled heat loss. Fibreglass, wool and rigid-panel insulation products can also perform well, but their effectiveness depends heavily on precise cutting, fitting and installation.
Spray foam can form part of an H1-compliant building design when it is correctly specified and installed. Compliance is based on the construction R-value of the complete wall, roof or floor assembly rather than the insulation product alone. The project designer must confirm the required R-values and compliance pathway for the building and climate zone.
Professionally specified and installed spray foam is suitable for residential buildings. Closed-cell spray foam helps control air and moisture movement, but the insulation, ventilation and wider building envelope must be designed together. Installation should be completed by trained applicators in accordance with the product documentation, safety requirements and building design.
Spray foam is designed to maintain its position and thermal performance over the long term. It does not rely on friction to remain in place and will not slump or settle in the same way some loosely fitted insulation products can. NZ Foam supports qualifying installations with a transferable 50-year limited lifetime product warranty.
Spray foam can be used in ceilings, external and internal walls, underfloor areas, mid-floors, masonry construction and skillion roofs. It adheres to common building surfaces, including timber, concrete and steel. Suitability depends on access and the building design.
Yes. Spray foam can be applied directly beneath suitable floors to create a secure insulation and air-sealing layer. Because it adheres to the substrate, it does not require supporting straps or fittings to hold individual insulation pieces in place. Adequate underfloor access is required for safe professional installation.
Closed-cell spray foam can add rigidity to some wall and roof assemblies, although it is not a replacement for structural framing or engineering. Spray foam can also help reduce outside noise and sound movement through gaps. The final acoustic performance depends on the complete wall, ceiling or floor system.
