EPS insulation shells for pipes
Expanded polystyrene (EPS) is used for thermal insulation not only in the form of standard flat boards, but also in a more specialized format - as protective pipe shells for pipelines and tubing systems.
The shells are produced in 2-meter sections. Both the inner and outer diameters can be customized. The shape of the internal and external contours can also be tailored. For example, if multiple pipes run parallel to each other, they can be grouped into a single housing. This results in a more compact cross-section with the same insulation thickness, which makes the system easier and faster to install.
It’s important to note that EPS has an operating temperature limit of +80 °C. Therefore, for insulating hotter pipes (such as steam lines or flue ducts), it’s necessary to first wrap the surface in a 2–3 cm layer of mineral wool. The EPS shell can then be installed over this protective layer.
For pipe insulation, we typically use EPS grade 100 (≈20 kg/m³).
