OPTIM-R Roofing System

The OPTIM-R Roofing System is perfect for projects that require the lowest U-value or the thinnest roof build-up. It is ideal for where there is little space for installing new roof insulation, for example buildings with planning height restrictions. The System comprises vacuum insulation panels (VIPs) and PIR infill boards. The infill boards can be cut to fit around problem areas such as roof lights, ventilator kerbs or drainage gutters.

Product Highlights

  • Optimum performance rigid vacuum insulation panel with a declared thermal conductivity of 0.007 W/mK

  • Ideal for constructions where a lack of construction depth or space is an issue

  • Ideal for new build and refurbishment
