Ravatherm XPS X Sheets


Exceptional Thermal Performance & Strength

Ravatherm XPS X (extruded polystyrene) insulation is renowned for its exceptional thermal performance, high compressive strength, and low water absorption, making it the preferred choice for specifiers in a wide range of demanding applications. Panel Systems supply Ravatherm XPS X sheets, and are able to supply our customers with either brand to large quantities at custom sizes.


Available in a number of different grades and sheet sizes to suit the end use

Sheets can be supplied hot-wire cut to any thickness from 6mm to 165mm at tolerances as low as +/- 0.25mm. (Standard tolerance +/- 0.5mm)

We offer a full 5-Axis CNC machining service, and can accept customers’ own drawings in a variety of formats

Manufactured to order in Sheffield, from stocked materials

Ravatherm XPS X Sheets

Ravatherm XPS X 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 cold stores, touring caravans, truck panels, building and curtain-walling.

Our distributorship with Ravago Building Solutions enables us to offer a comprehensive range of Ravatherm XPS X sheets, hot-wire cut to any thickness and CNC machined components.

Panel Systems hold the largest single stocking point of Ravatherm in the UK at 3000m3, and our warehouse is 5 mins from Junction 31 of the M1 meaning that it is ideal for both delivery and collection of orders.

Hot-Wire Cutting

Panel Systems has one of the largest specialist fabrication units for the hot-wire cutting of Ravatherm XPS X in Europe. Our hot-wire cutting facilities include large volume and small batch capability. Sheets can be cut to a thickness of 6mm and by 0.5mm increments to around 165mm.

Our purchasing power enables us to source an extensive range of fabrication sheets from our suppliers with lengths up to 3050mm, widths up to 1220mm and thickness up to 165mm. This ensures that our customers are able to achieve their required sheet size with the minimum of waste.

The hot-wire cut surface of Ravatherm XPS X is ideal for the application of adhesives and is fully compatible with metals, plastics, and timber-based products for bonding purposes.

CNC Machining

Panel Systems operates three large 3-axis CNC routers able to machine sheets up to 3650mm x 1525mm. 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.


Ravatherm XPS X sheets are available in the following sizes:

Length x Width (mm)Thickness Range*
2500 x 6003mm - 160mm
2150 x 6003mm - 145mm
3050 x 7503mm - 115mm
1940 x 8103mm - 115mm
2150 x 9403mm - 115mm
2150 x 12003mm - 110mm
2400 x 12003mm - 110mm
3050 x 12203mm - 110mm

*Sheets can be cut to any thickness within the range

Ravatherm XPS X is an excellent core material for a wide range of sandwich panel applications. The key benefits of Ravatherm XPS X are:

  • High Mechanical Strength in compression, tension, bending and shear. Panels manufactured with Ravatherm XPS X exhibit high impact strength and resistance to dynamic loading.
  • Lightweight – Ravatherm XPS X has a high strength to weight ratio
  • Good Thermal Insulation – Ravatherm XPS X has excellent thermal properties.
  • Water and Vapour resistance – The closed cell structure of Ravatherm XPS X ensures that performance is maintained even in external situations or where moisture exists.
  • Bonding Surface – Ravatherm XPS X has a smooth dust free surface and is ideal for bonding. Hot-wire cut Ravatherm XPS X is available and provides an excellent bonding surface combined with consistent thickness for high quality bonding.

Blowing Agents

The production of Ravatherm XPS X 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. 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 very high strength-to-weight ratio of composite panels provide significant benefits in the design of caravans and motorised homes. Ravatherm XPS X is ideal as a core material for composite panels. Its high mechanical strength is suited to the dynamic loads attached to these applications. It will also help in the design to reduce the number and cross-section of wooden inserts. Ravatherm XPS X also provides excellent insulation performance even at low temperatures during winter months.

Truck Panels

The technical requirements for refrigerated truck bodies are defined by regulations and by economic considerations, which include the resale value of a vehicle. To be cost effective, refrigerated truck bodies must be insulated effectively whilst also being lightweight and built with highly durable materials to last for decades. Panels with Ravatherm XPS X core material have been used in the manufacture of floors, walls, and roofs of refrigerated truck bodies for more than 25 years with proven success. Ravatherm XPS X PLUS RTM is designed to meet the needs of the refrigerated truck market. All products are produced in a range of thicknesses to meet the needs of the specific application. Panel Systems offer a comprehensive fabrication service to provide complete kits and/or components for the production of truck panels.

Underfloor Heating

Ravatherm XPS X is ideally suited to both water and electric matting underfloor heating systems due to its high compressive strength and impressive thermal insulation properties. Waterproof, rot and mould resistant and lightweight, Ravatherm XPS X is available in a range of thicknesses from 6mm upwards. It also offers high levels of impact resistance. In hot water based underfloor heating systems, Ravatherm XPS X can be CNC machined to accept water pipes. The density of Ravatherm XPS X is such that high quality and consistent grooving is achieved to ensure a good fit for the water pipes. For electric matting systems where there is an existing un-insulated floor slab, sheets can be readily cut and fitted by hand. Wood laminates can be laid in direct contact. Floor tiles can be laid using any water-based tile adhesive.

Frequently asked questions

What is Ravatherm XPS?2023-06-23T10:05:07+01:00

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.

How does Ravatherm XPS X react to fire?2023-06-30T12:20:59+01:00

Ravatherm XPS X is rated Euroclass E under BS EN 13501-1 Reaction to Fire test. For more information regarding Ravatherm XPS X’s reaction to fire, please refer to Ravago’s comprehensive product brochure.
