Why Spray Foam Outperforms Traditional Insulation

Spray foam insulation is reshaping how Australia builds for energy efficiency, comfort, and long-term durability. As climate targets tighten and construction standards evolve, traditional insulation materials can no longer meet the demands of modern buildings. Spray foam delivers a superior, high-performance solution that enhances structural integrity, controls air movement, and dramatically improves thermal performance for decades.

Pacific Urethanes brings world-leading polyurethane technology to the Australian and New Zealand market through our partnership with Huntsman Building Solutions. Together, we deliver systems engineered for exceptional performance in residential, commercial, industrial, and infrastructure applications.

Why Polyurethane Foam Insulation?

Cost Effective

Polyurethane spray foam delivers outstanding long-term value compared to traditional insulation. While the upfront installation may be different, spray foam reduces ongoing heating and cooling costs by preventing air leakage, eliminating cold spots, and creating a tightly sealed building envelope.

Integrated benefits:

  • Reduces energy consumption by preventing thermal bridging and uncontrolled airflow

  • Lowers HVAC operating costs and improves system efficiency

  • Long lifespan with minimal maintenance

  • Reduces risk of moisture-related damage, saving repair costs

  • Cost effective over the entire building life cycle

Versatile With Excellent Thermal Protection

Polyurethane is a highly versatile insulating material that expands to fill gaps, irregular shapes, and hard-to-reach cavities where traditional insulation cannot form a seamless barrier. This versatility delivers consistent thermal performance across walls, roofs, floors, and attics.

Integrated benefits:

  • Outstanding thermal resistance due to closed-cell or open-cell formulations

  • Expands to create a continuous, joint-free insulating layer

  • Adheres to most construction surfaces, even complex geometries

  • Available in two system types:
    Open-Cell: acoustic absorption + air barrier
    Closed-Cell: high R-value + structural strength + vapor barrier

  • Suitable for residential, commercial, industrial, and agricultural buildings

Sustainable Solution With Fire Properties

Spray foam insulation contributes to sustainable and safe building design. Its fire performance can be engineered to meet strict building codes, while its insulating power supports low-carbon, energy-efficient construction.

Integrated benefits:

  • Available in CodeMark-certified systems for fire safety compliance

  • Zero Ozone Depletion Potential (Zero ODP)

  • HFC-free blowing agents reduce carbon emissions by up to 36.5 times

  • Excellent air sealing reduces long-term energy use

  • Resistant to mould, moisture, and deterioration, reducing material waste

  • Supports healthier indoor environments by controlling condensation

AMBA (Australian Modern Building Alliance)

Polyurethane spray foam aligns with the direction of Australia’s modern building performance standards. As an AMBA-recognised polymer-based solution, PU insulation supports national energy-efficiency policies, sustainable construction frameworks, and improved building durability.

Integrated benefits:

  • Recognised as a key contributor to meeting NCC energy efficiency requirements

  • Helps achieve high-performing building envelopes with reduced operational emissions

  • Supports Australia’s transition to low-energy, low-carbon buildings

  • Long-term durability means fewer replacements and reduced environmental impact

  • Backed by industry research, innovation, and building code compliance

Our Spray Foam Technology

Our spray foam technology uses next-generation, HFC-free blowing agents that reduce carbon emissions by up to 36.5 times compared to traditional insulation systems. This makes our solutions significantly more environmentally responsible while delivering industry-leading performance.

We also supply CodeMark-certified spray foam systems, providing independent verification of fire performance, quality, and compliance with the National Construction Code (NCC). These certifications set our products apart in the market and give architects, builders, and developers confidence in every application.

Spray Foam

Open-Cell Insulation

Open-cell spray foam delivers a superior air barrier to traditional insulation in walls, floors, attics, etc. Spray Foam insulation will adhere to most construction surfaces and expand to create an airtight building envelope. We pioneered the development of open-cell spray foam insulation through innovative technology and is now internationally prevalent as mainstream insulation.

Closed-Cell Insulation

Closed-cell spray foam insulation outperforms traditional insulation by providing an air, water and vapor barrier in a single component. Spray foam insulation adheres to most surfaces and expands to create a seamless, airtight building envelope. In addition, it offers outstanding high-performance options for commercial, residential, institutional, industrial or agricultural applications.
