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.

Spanline Canberra - Especially Scott have been so amazing from the very beginning of installing my sunroom, I had and still have so many questions and he is always so willing to answer them and cross check everything so he has the right answer for me. He goes above and beyond answering my email after hours and on weekends which I think is just such amazing service . I can’t thank Scott and his team enough and I can’t wait for my sunroom to be finished in a couple of months
Well done Josh. Very professional job. We would definitely use Spanline again. Very happy with your work
I have referred Spanline Australia for many of my Clients in Sydney, who are in need of a quality crafted carport, patio or alfresco area, and we have received overwhelmingly positive feedback. From start to finish, their team was professional, efficient, and highly skilled. The quality of their workmanship exceeded my expectations, and the final result truly enhances the appearance and functionality of my client’s homes. I highly recommend Spanline to anyone in need of outdoor living or improved home utility. They deliver top-notch service and outstanding results.

Extremely happy with completed roof we had Spanline Port Stephens erect over our external deck area. Their professionalism and attention to detail throughout our product selection / build process was amazing and we have received a great deal of positive feedback from our family and friends about the quality of the product and workmanship. Many thanks to Steve and Simone.
We have used Spanline for two renovations recently and couldn't be happier with the process, from Seb Godfrey coming out to measure and quote, to material selection and the build process.Where possible they sought to re-use existing materials and structures, offering different materials and options to really try and meet our budget and still get an amazing result.The workmanship is amazing and especially in the instance of our back deck it just linked the house and our yard together in a way our previous mod-wood deck (which was only two years old and had collapsed) simply could not.I cannot recommend Spanline highly enough. The initial quote may seem expensive but I can't reiterate the work quality, the dedication of the staff and the end product is absolutely worth it and I wish I had done it in the first place. I'm looking forward to working with them again in future for other renovations I'm planning.

Spanline recently installed an enclosed glass room on our back deck. They done an awesome job. From start to finish we found this company very professional to deal with. We are very happy with our new space. Great people. Will definitely use again.

From the initial contact with Chris and Mel, all dealings with Spanline people were positive and friendly. The team organised all necessities from Council approval, through the engineer drawing up the plans via an onsite visit, to the delivery and construction of the carport.I initially thought the timeframe was excessive but they moved my construction forward when there was a cancellation. Rain slowed things down but the carport was erected within 3 workable days (allowing for the curing of the concrete).Neighbours have remarked positively on the look of the carport and that it has enhanced the front of the house.Once the carport was erected, a local plumber completed the work by connecting the carport roofing to the required overflow pipes.In summary, a great piece of work, organised by a very friendly and professional organisation.
