Yanming Coolroom Panels

Insulated sandwich panels are single piece factory engineered units typically comprised of two metal faces bonded to a fully insulating core.  The facings are fully bonded to the core so that the panel acts compositely when under load, in most cases, providing free standing and load bearing panels. 

The majority of EPS panels manufactured in Australia are made with an EPS core sandwiched between two Colorbond steel facings.

EPS Panel is a proven construction material well-suited to the extremes of the Australian climate. It is a cost-effective, lightweight construction material with excellent insulation properties.

The advantages of EPS Panel include:
  • High load bearing capacity at low weight
  • Effective and durable thermal insulation
  • Absolute water and vapour barrier
  • Air-tightness for controlled environments
  • Long life, low maintenance
  • Lightweight, fast and economic construction
  • Hygienic food grade finish
  • Most cost effective insulation material available
  • Australian manufacture permits shorter lead times and prompt delivery

EPS has been a material of choice for over half a century because of its technical versatility, performance and cost effectiveness. It is widely used in many everyday applications where its light weight, strength, durability, thermal insulation and shock absorption characteristics provide economic, high performance products.

Light Weight

EPS is an extremely lightweight material which is not surprising considering it is comprised of ~95% air. This characteristic makes it ideal for use in packaging as it does not significantly add to the weight of the total product thereby reducing transportation costs. Energy consumption for transport fuel is also reduced and vehicle emissions minimised – all contributing to lower global warming.


The exceptional durability of EPS makes it an effective and reliable protective packaging for a wide range of goods. The cellular structure of EPS makes it dimensionally stable and therefore does not deteriorate with age. EPS is also odourless and non-toxic.

Moisture Resistance

EPS is a closed cell material and does not readily absorb water. There is no loss of strength in damp conditions, making EPS ideal for cool-chain products. The material is moisture resistant, so the highest hygiene requirements are met. The ability of EPS to resist moisture also lends itself for use in fishing floats and marina buoys. Even when subjected to prolonged saturation in water, EPS will still maintain its shape, size, structure and physical appearance with only a slight reduction to its thermal performance.

Thermal Efficiency

The superior thermal efficiency of EPS makes it ideal for packaging any product that is sensitive to temperature change. Products enclosed in EPS containers can be maintained for long periods at temperature above or below ambient conditions and can be protected from sudden temperature changes that can occur in the transport through different climatic zones. Examples include fresh produce and seafood as well as pharmaceutical and medical products.

Shock Absorption

EPS exhibits excellent shock absorbing characteristics making it the first choice for packaging of a wide range of products including appliances, electronic products, computers and chemicals.


EPS can be manufactured to almost any shape or size, or it can be easily cut and shaped when required to suit any application. EPS is also produced in a wide range of densities providing a varying range of physical properties. These are matched to the various applications where the material is used to optimise its performance. In addition, EPS is also compatible with a wide variety of materials.

Ease of Use

For building and construction applications, EPS is considered to be one of the easiest materials to install on site. It is normally supplied in sheet form however can also be moulded into shapes or in large blocks.

Most panel systems use Expanded Polystyrene (EPS), a product that's been in use for over 50 years. EPS has an R-Value of 3.5 to 4.0 per inch.

Another structural panels use Polyurethane, which was invented to improve upon the shortfalls of EPS. Polyurethane has an R-Value of 7.0 to 7.5 per inch, making it the world's highest-rated insulation per inch, which explains why it's the choice of manufacturers of everything from freezers to water coolers to refrigerated semi-trailers.

Better Fire Resistance

EPS can be damaged by temperatures over 180 degrees, so it offers little fire resistance. Class I rated polyurethane—the kind Thermocore uses—can withstand temperatures of 750 degrees without damage. At those temperatures, it chars but does not burn, so it minimizes the spread of fire. In fact, the material normally self-extinguishes.

Better Moisture & Chemical Resistance

Building materials are rated for permeability, or how much moisture can seep through them. Typical EPS is much more permeable than polyurethane, which is why many EPS manufacturers include interior and exterior vapor barriers when calculating R-Values (be sure to read the fine print when comparing). In addition, most over-the-counter chemicals won't damage polyurethane, but common petroleum-based chemical products such as insect sprays and many construction adhesives will degrade EPS.

Greater Density For Greater Strength

At a minimum density of 2.2 pounds, Thermocore panels are more than twice as dense as EPS, which provides greater strength.

Less Environmental Impact

Typically, EPS panels are created in standard sizes and cut at the jobsite to fit your home's requirements. The scraps usually cannot be recycled. In comparison, Thermocore panels are designed and constructed to your specific plans, so waste is minimal. The polyurethane we use acts as its own adhesive, for a strong, consistent bond across the entire panel. EPS manufacturers have to use separate glues, with the quality of the bond dependent on how evenly the glue is spread and how long it dries.

More Value For Every Dollar

There's a good reason EPS panels appear to be cheaper: they cost less to make. EPS manufacturers buy materials in finished form and use very little equipment and labor to produce panels. Of course, that's offset by significantly more equipment and labor at the jobsite.
