Spray Foam Solutions supplies and installs high-performance closed cell spray foam insulation for commercial, industrial, and specialised residential applications.

We apply strict standards when selecting closed cell insulation products, ensuring they meet safety, performance, and environmental requirements appropriate for Australian conditions.

What Is Closed Cell Foam Insulation?

Closed cell foam insulation is a high-density spray foam that expands on application to form a rigid, closed-cell structure. Once cured, it creates a strong, continuous insulation layer that resists air movement and moisture ingress.

Due to its density and strength, closed cell foam insulation provides high thermal performance within a thinner profile and is commonly used in applications where moisture control, durability, and added structural rigidity are required.

Our Closed Cell Foam Insulation Standards

Before offering any closed cell foam insulation product to our clients, we ensure it meets the following criteria:

• Highly flame retardant
• Zero Ozone Depletion Potential (ODP)
• Zero Global Warming Potential (GWP)
• Free from Volatile Organic Compounds (VOC-free)
• Non-hazardous when correctly applied
• Fully compliant with relevant Australian Standards

These standards ensure a safe, durable, and environmentally responsible insulation solution.

AUSFOAM 30 Closed Cell Spray Foam

The closed cell spray foam insulation product we use is AUSFOAM 30, supplied by Australian manufacturer Australian Urethane Systems.

AUSFOAM 30 is a low-density, rigid polyurethane closed cell foam system, specifically developed to deliver high thermal performance with enhanced fire retardant properties.

It is designed for use in commercial and industrial wall and ceiling insulation, where foam is applied into stud work or framed construction.

Benefits of AUSFOAM 30 Closed Cell Foam Insulation

• High R-value per thickness
  (Approx. R6.0 per inch for closed cell foam, compared to R3.5 per inch for open cell foam)
• Excellent air sealing, eliminating air infiltration
• Helps control moisture and condensation
• Reduces convective heat transfer within walls and ceilings
• Eliminates wind washing
• Performs effectively across low and high temperature ranges
• Improves overall efficiency of heating and ventilation systems

Energy Efficiency & Return on Investment

By minimising air leakage and providing superior insulation performance, closed cell spray foam insulation can reduce heating and cooling demands within a building.

In many applications, this allows for:

• Smaller heating and cooling systems
• Lower ongoing energy costs
• Improved internal comfort year-round

Energy savings of up to 40% may be achieved when compared with conventionally insulated buildings, depending on design and usage.

Can Closed Cell Spray Foam Be Painted?

Yes. Closed cell spray foam insulation can be painted once cured.
