How to Transform Your Home with Insulated Wall Panels & Roof Panels

Insulated wall panels and roof panels are a great way to transform your home or outdoor living area. They deliver outstanding insulation qualities to provide year-round comfort. If you’re considering them for your next home project, this article is for you.

Benefits of Insulated Wall and Roof Panels

Insulated wall and roof panels are an excellent investment for any design-centric homeowner because they can:

  • Provide year-round outdoor comfort through increased thermal efficiency.
  • Reduce loud noises such as heavy wind or rain, creating a more peaceful living space.
  • Enhance the aesthetics and kerb appeal of your home.
  • Spanline’s range of Ezi Struct® panels are designed and manufactured to withstand Australian conditions and are strong and durable..

Types of Insulated Wall and Roof Panels

Insulated wall panels and roof panels are also known as “sandwich panels” and comprise a core of insulating material sandwiched between two metal or polymer composite skins.

  • Expanded Polystyrene (EPS) Panels have a high R-value which is maintained long after installation, meaning they are excellent at preventing heat transfer. They are lightweight and easy to install making them a popular choice for residential and commercial building projects. The panels are moisture-resistant and do not absorb water, making them ideal for use in areas with high humidity or moisture. EPS is environmentally friendly as it comprises 98% air and is also fully recyclable.
  • Polyurethane (PU) Insulated Panels are known for their excellent insulation properties and low moisture permeability. However, they can be more expensive and harder to install than other options and they can also lose their R-value over time.
  • Fibreglass Panels are made of fibreglass which traps air and slows the transfer of heat. The advantage of fibreglass panels is their lightweight nature, however, they are not as durable nor as insulative as other options.
  • Mineral Wool Panels are made of natural or synthetic mineral fibres and have a higher R-value than fibreglass. Another feature of mineral wool panels is their excellent sound absorption, which can reduce noise levels in buildings.
  • Vacuum Insulated Panels (VIPs) are high-performance panels that provide excellent insulation values. They are commonly used in applications where space is limited. VIPs have a very high R-value, which makes them extremely efficient at reducing energy consumption. However, they are expensive to produce and install and cannot be cut to size, limiting their practical use in many residential applications.
  • Cork Panels are a natural insulation material that can be used in both roofing and walling applications. The key advantage of cork panels is their ability to resist moisture, making them ideal for use in damp environments. However, they are often less durable compared to other options and may require more maintenance over time.
  • Extruded Polystyrene (XPS) Panels: These panels are rigid foam boards that offer superior moisture resistance, making them ideal for wet or humid environments like swimming pools and basements. They have a high R-value, meaning they are excellent at preventing heat transfer, and high compressive strength, which makes them durable.

Spanline’s range of Ezi Struct® insulated panels offer superior protection against the elements and have high thermal insulation and noise reduction qualities. The EPS core is covered with a double layer of Colorweld® steel for maximum strength, insulation and durability. An interlocking system makes the panels easy to install and they come in a range of profiles and thicknesses to suit your desired insulation rating or free span requirement.

Build it your way!

Insulated wall and roof panels are a great way to add extra functionality to your outdoor space without compromising on style.

Consulting with an expert is recommended to ensure proper installation. Following the maintenance guidelines is essential for maximising the benefits and longevity of insulated panels in your home.

For 38 years Spanline has provided customers with the highest quality materials and service, evidenced by our excellent customer feedback.

We pride ourselves on our expertise in designing, manufacturing, and installing custom-made home additions such as glass and screened rooms, patios, and carports.


The lifespan of insulated roof panels depends on factors such as the quality of materials, maintenance, and environmental conditions. High-quality materials such as pre-painted steel with magnesium added for superior corrosion resistance can last for many years.

Extreme weather conditions and UV radiation can affect the panels’ lifespan. Generally, insulated roof panels can last for 20-30 years, but individual circumstances may vary.

Spanline’s Insulated Wall and Roof Panels are known for their durability and longevity. Our Ezi Struct® and Climatek® panels are designed and made in Australia from high-quality materials that withstand Australia’s harsh conditions. They will also withstand the test of time.

Our insulated wall panels are made from a combination of expanded polystyrene foam (EPS) and pre-painted steel with magnesium. EPS is a lightweight, durable and versatile material that is known for its excellent insulation properties. The pre-painted steel with magnesium provides strength and durability, making the panels resistant to weather damage, impact and scratches.

We were looking to update our entertaining area which is quite large and called into Spanline ACT after driving past the showroom. Everything from the first meeting with Scott Basman has been fantastic. Scott had renderings completed so we could visualize a completed project.Our project is still a working progress, very happy with Scott, Dan, Tom and the entire team and can’t wait for our completion
Spanline Coffs Harbour were excellent to deal with. They were very knowledgeable & couldn’t do enough to help us. Thank you!

We had a rather small modification made to our sunroom, which was originally built by Spanline over 10yrs ago. The job turned out just as we had hoped. Salesman Frank and supervisor Trevor were quick to provide replies to our queries and updates throughout. We consider that very important, so that we know we haven't been forgotten after signing on the dotted line. All members of the team we spoke with were easy to talk to, accepted our questions and input and made us feel part of the process. Cannot recommend them highly enough.Tony Zahra

Amazing job by Spanline!! Constant consultation during the build of our deck roof, and with the organising of electrical work to light switches and installation of ceiling fan. We now enjoy entertaining on the covered deck enjoying the sunset and the view to the escarpment
After some research we contacted Spanline about an addition for our house. Scott Basman came out and talked to us about what we wanted from the space. He worked with us on the design, he is very knowledgeable and made sure it was everything we wanted. Lachlan, Adrian and Jake were also amazing throughout the build process, now we have a massive indoor/outdoor space which is perfect for our needs.
