About This Guide
This guide will look at the benefits and applications of Ravatherm XPS and its suitability for a wide range of applications.
Key benefits of Ravatherm XPS
Ravatherm XPS (formerly known as Styrofoam) has a number of properties that make it suitable for use across a range of applications including building, structural panels and temperature controlled trailers.
Thermal Conductivity Performance and U-values
Thermal conductivity of a material is known as the K-value and is a means to determine how effective a material is as an insulator. The lower the K-value the better.
Thermal resistance (R-value) is a measure of heat flow through a material and is a function of material thickness and the K-value. When designing a structure, the R-value for each element of the structure is determined and summed to formulate the total resistance (Rt) of the structure. The reciprocal of Rt represents the U-value of the structure. With it’s low thermal conductivity and range of thickness Ravatherm XPS is designed to achieve U-values for a range of building elements.
The long-term performance of an insulation material requires a closed cell structure. This ensures low water absorption to prevent thermal conductivity degradation. Ravatherm XPS is a 100% closed cell material and will provide long term insulation as a result of it’s low water absorption. Ravatherm XPS is resistant to performance degradation as a result of freeze/thaw cycles.
Excellent compressive strength
In load bearing applications such as floors, it is vital that the insulation is capable of handling the design loads. Ravatherm XPS offers a range of compressive strengths to meet the needs of heavy loads.
Ravatherm XPS is an extruded polystyrene. Polystyrene is fully recyclable via a range of different technologies including incineration and remelting.
Services offered by Panel Systems
Ravatherm XPS can be used for a huge range of applications and is supplied in a number of forms to meet project requirements. Panel Systems is able to supply and cut Ravatherm XPS in a number of ways and forms.
Hot Wire Cutting of Ravatherm XPS
Panel Systems is able to hot wire cut Ravatherm XPS blocks to a range of thicknesses between 3mm and 160mm to suit customer requirements and bespoke projects. In addition to cutting blocks to the desired thickness, it is also possible to cut the material vertically to fit even more applications. Cutting tolerances are +/- 0.5mm.
Applications for hot wire cut Ravatherm XPS sheets include:
- Sandwich panels
- PVC door U-panels
- Underfloor heating
- Vehicle bodies
- Lightweight furniture panels
Sanding of Ravatherm XPS
Where closer tolerances are required, for instance bonding thin skins, Panel Systems offer a sanding service with improved tolerance to +/- 0.25mm.
Grooving of Ravatherm XPS
When manufacturing large panels for temperature controlled vehicles and where a hot-wire cut sheet is required, Panel Systems is able to groove sheets to improve the laminating performance of the Ravatherm XPS.
CNC Machining of Ravatherm XPS
Panel Systems offer a full CNC machining service of Ravatherm XPS. We have extensive CAD/CAM software capability to support four CNC routers, two of which are 5-axis. Typical markets include machining of grooves for hot water underfloor hearing systems, 3-D shapes for OEM markets and modelling applications.
Ravatherm XPS Product Options & their applications
In addition to Ravatherm XPS sheets that can be cut to size, Panel Systems also supplies the materials in a number of other forms to suit a variety of applications.
Ravatherm XPS blocks
While Ravatherm XPS can be supplied as cut sheets to suit individual projects, Panel Systems also supplies the material in blocks which are supplied at their natural thickness, with no cutting required.
These blocks can be supplied for a number of uses in which customers require a lightweight structural foam. Applications include:
- Engineering prototypes
- University research
- Model making and prototypes
- Theatre props
- Point of display
Ravatherm XPS Flooring Grade
Due to its extremely high compressive strength and insulation qualities, Ravatherm XPS is supplied for flooring applications. Flooring grade Ravatherm XPS foam is available in a number of compressive strengths to make it suitable for the loading requirements of individual projects. For example, a domestic project would require far less strength than the floor of a factory which must support heavy machinery.
Flooring grade Ravatherm XPS can also be used for:
- Basement floors
- Under slab floor insulation
Ravatherm XPS Roofing Grade
Ravatherm XPS is commonly used in the building of flat roofs and other roofing structures. It’s thermal performance and resistance to water and frost make it ideal for this purpose.
Roofing grade Ravatherm XPS is commonly used for:
Inverted flat roofs & roof terraces
When installed as part of an inverted flat roof or roof terrace, Ravatherm XPS provides protection against UV radiation, protects the waterproofing layer of the roof from temperature variations and helps to prevent degradation caused by extreme weather conditions.
Car park decks
Ravatherm XPS boards provide high strength and durability for car park decks which are exposed to much higher static and dynamic loads than other roof terraces.
Ravatherm XPS RTM Grade for Refrigerated Trailers
Ravatherm XPS is the core material recommended for the sandwich panels used to construct the walls, roofs and floors of refrigerated vehicles.
It allows the truck bodies to be effectively insulated whilst helping to keep the weight of the vehicle as low as possible in order to save on fuel consumption and ensure that the vehicle is constructed with long-lasting materials which will last for a number of years.
Craft foam is made from Ravatherm XPS sheets and can be used for a wide range of craft applications. The material’s small, uniform cell structure makes it perfect for cutting into with modelling tools in order to create three-dimensional models.
