R-WALL Insulated Concrete Formwork (ICF) uses Extruded Polystyrene (XPS), rather than Expanded polystyrene (EPS) used in older modular forms of ICF. To find out the difference between XPS and EPS click below.
The use of XPS combined with R-WALLs build and design versatility is what sets R-WALL above its competitors.
R-Board is supplied in a stunning gunmetal grey finish (as shown in the image to the left).
The R-Boards are supplied in various thicknesses, as the thickness increases so the U-Value decreases and energy efficiency improves.
R-Boards are supplied in a choice of lengths, the 1.25m boards or our New 2.5m board!
R-Boards come in the thickness shown below as standard. By Special order we can obtain the 150mm and 200mm board further improving on U-Values acheivable.
U-Value = 0.27
U-Value = 0.18
U-Value = 0.14
U-Value = 0.11
Again by Special order we can combine any of the above R-Board thicknesses for example 100mm external face and 75mm internal. Examples and resulting U-Values are detailed in the illustration below.
