What is Ravatherm XPS?
Ravatherm XPS is an extruded polystyrene. It was first developed and produced in the 1940’s by Dow Chemical Company in the USA. The process of extruding polystyrene results in a material with uniformly small, closed cells and an unrivalled set of properties which make it ideal for insulation and also as a core in lightweight structural panels. Ravatherm combines low thermal conductivity and low water absorption to make it the choice of specifiers in a wide range of demanding insulation applications.
Ravatherm also has excellent mechanical properties including high strength in compression, tension, bending and shear which are essential for a core material in structural panels used in a range of markets including coldstores, touring caravans, truck panels, building and curtain-walling. The small uniform cell structure of Ravatherm is also ideally suited for use in markets such as hobby and craft where traditional modelling tools can create three-dimensional models.

Panel Systems has one of the largest specialist fabrication units for the hot-wire cutting of Ravatherm in Europe. Hot-wire cutting facilities include large volume and small batch capability. Blocks and/or sheetscan be cut to a thickness of 5mm and by 0.5mm increments to around 150mm.
Our purchasing power enables us to source an extensive range of fabrication blocks from Ravago Building Solutions with lengths up to 3025mm, widths up to 1200mm and thickness up to 165mm. This ensures that the customer is able to achieve his required sheet size with the minimum of waste. The hot-wire cut surface of Ravatherm is ideal for the application of adhesives and is fully compatible with metals, plastics, and timber based products for bonding purposes.

Panel Systems operates three large 3-axis Cnc routers able to machine sheets up to 3650mm x 1525mm. In the case of Ravatherm, blocks up to 165mm are machined. In house CAD/CAM facilities enable us to rapidly prototype customer requirements and undertake both large and small production runs.
We are able to import an extensive range of file formats eg. dxf, dwg and we will also create CAD drawings and machining programs from customers rough outlines.

The production of Ravatherm XPS is primarily based on the extrusion of polystyrene with a blowing agent. There are two types of blowing agents used in the production of Ravatherm. These are HFO-1234ze and CO2. Both have zero ODP and low GWP.
Type X which are foamed by a HFC. The ODP and GWP of the HFC foaming agent are 0 (kg CFC11 equivalent/kg HFC) and 1300 (kg carbon dioxide/kg HFC) respectively.
Type A which are foamed by carbon dioxide. The ODP and GWP of the carbon dioxide foaming agent are 0 (kg CFC11 equivalent/kg carbon dioxide and 1 (kg carbon dioxide/kg carbon dioxide) respectively.
The vast majority of Ravatherm waste created during our production is compacted and recycled.
For some of our customers it has proved to be beneficial for Panel Systems to undertake additional fabrication and machining to minimise their waste.
We pride ourselves on our high level of quality & service and all our products are manufactured to British Standard BS EN ISO 9001:2015. We keep extensive stocks at our Sheffield warehouse close to Junction 31 off the M1, ready for collection or distribution across the UK.
