Polyethylene Insulation

Polyethylene insulation is a high-performance, versatile insulation solution trusted by industry professionals for its superior moisture resistance, thermal efficiency and flexibility. At FM Insulation, we leverage our 30+ years of experience to supply premium polyethylene insulation products for commercial and industrial applications, ensuring optimal energy efficiency and condensation control for your projects.
What is polyethylene insulation?

Polyethylene insulation is a closed-cell foam insulation material with excellent thermal and moisture resistant properties. This lightweight, flexible material has become increasingly popular in HVAC, refrigeration and plumbing applications due to its outstanding performance characteristics.

The manufacturing process of polyethylene insulation

The manufacturing process of polyethylene insulation involves the controlled expansion of polyethylene resins to create a closed-cell foam structure. This process results in a material with exceptional moisture resistance, flexibility and thermal insulation properties. Various facings, such as reflective facing, can be added to enhance performance for specific applications.

At FM Insulation, we’ve been supplying polyethylene products for nearly 20  years, witnessing firsthand its evolution and increasing popularity. Known for its excellent moisture resistance, polyethylene insulation offers superior thermal properties and condensation control, making it ideal for both commercial and industrial use.

Key benefits and advantages of polyethylene insulation

At FM Insulation, we stock a wide range of insulation products, allowing us to provide unbiased comparisons. Our extensive experience has shown that polyethylene offers several key benefits and advantages over other insulation types:

Superior moisture resistance:

Polyethylene features a closed-cell structure that provides an excellent vapour barrier, preventing moisture ingress. This makes it ideal for refrigeration lines, cold water pipes, and air conditioning systems where condensation control is critical.

Excellent thermal insulation:

Polyethylene’s closed-cell structure effectively reduces heat transfer. This results in improved energy efficiency and lower heating and cooling costs for your projects.

Flexibility and ease of installation:

The flexible nature of polyethylene insulation allows it to be easily installed around bends, fittings, and in tight spaces. This reduces installation time and ensures a complete thermal envelope.

Long-lasting durability:

Polyethylene maintains its performance over time, even under varying temperature and humidity conditions. It doesn’t become brittle or deteriorate, ensuring consistent insulation performance throughout the life of the system.

Lightweight structure:

The low density of polyethylene insulation makes it easy to handle and install. This lightweight characteristic doesn’t compromise its insulation effectiveness.

Chemical resistance:

Polyethylene is resistant to many common chemicals, acids, and solvents. This makes it suitable for use in various industrial environments where exposure to such substances may occur.

Cost-effective solution:

Polyethylene offers excellent performance at a competitive price point. When considering the full lifecycle costs, including installation and longevity, it represents an economical insulation choice.

Enhanced with facing:

Our faced polyethylene products provide additional radiant heat reflection, boosting the overall thermal performance of the insulation system.

Low water absorption:

Polyethylene’s naturally hydrophobic properties prevent water absorption, reducing the risk of insulation degradation and maintaining thermal performance over time.

UV Resistance

Whilst our polyethylene material is classified as UV Resistant to Australian Standards, we do not recommend its use in external applications without additional protection.
