Panel Construction

State of the art 100mm polyurethane rigid foam core, injected into an interior and exterior metal colourbond steel. All panels have a tongue and groove construction encompassing a cam locking fastener, operated by a hex wrench. Access holes are sealed with a vinyl snap-in cap.

Difference between EPS panel and polyurethane

Thermocore SIPS Compared to EPS Panels

Thermocore panels may look like other structural insulated panels, but looks don’t tell the entire story. 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.

Thermocore 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 job site 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 job site. Thermocore starts with raw materials and custom manufactures each panel to your plans. But although it costs us more to make panels, that cost is offset by the lower labor and energy costs, so while EPS may appear to be cheaper, Thermocore SIPS construction is a much better value.

Monoblock Units

Slide in units with an extensive range of capacity sizes available, for chiller or freezer situations. Simple to install and remove for servicing, built in defrost and easy to use control panel. Single phase 240v plug in. Standard temperatures range from –10° to +10° for chillers and –10° to –25° for freezers.
