R-WALL is a type of Insulated Concrete Form (ICF), meaning two panels of insulation are installed and the cavity filled with concrete. The majority of ICF systems use EPS, however, R-WALL uses Ravatherm XPS X 300 SB XPS boards supplied by Ravago.

Ravatherm XPS X 300 SB is a flame retarded XPS board with exceptional thermal performance and a Global Warming Potential (GWP) of less than five. This is important to R-WALL’s objective of not only building an energy-efficient future but doing so in an environmentally conscious and sustainable way.

Natalie Sutton, Account Manager, Ravago Building Solutions, said: “Our range of high-performance XPS insulation products offer exceptional thermal performance and they are produced at our plant in King’s Lynn, ensuring a 3-4 day lead time for delivery to site. Ravatherm XPS X 300 SB combines high compressive strength, low moisture uptake and exceptional lambda values into a product ideally suited for a range of applications.”

Lisa Trewin, Director at R-Wall, said: “We chose to work with Ravago for its high-quality products, continuous dedication to development and innovation within the industry, and its environmentally conscious production methods.

The Ravatherm XPS X 300 SB board delivers outstanding thermal performance as demonstrated by its lambda values which enables us to provide our customers with the most energy-efficient system on the market. R-WALL is currently the leading ICF company for the lowest U-Value to wall widths, whilst being able to maintain that all-important maximum 4-hour burn rating”.
