Choosing the best inverted roof insulation is important for any project

The OPTIM-R E Inverted Roofing System is our latest innovation in vacuum insulation technology . The OPTIM-R Vacuum Insulation Panels (VIPs) are encapsulated in a durable protective coating, providing increased robustness and easier handling, making them the ideal solution for constructions with limited depth or space.

Our range of rigid extruded polystyrene insulation (XPS) products are suitable for use in a variety of inverted roof systems, including green roofs and protected membrane flat roofs. With minimal water absorption and high compressive strength, they are built to withstand the freeze-thaw process, ensuring long-term performance. The insulation boards are easy to handle and install compared to other commonly used insulants, making them perfect for both new build and refurbishment projects.

Our product range also includes a water-infiltration reduction membrane, specifically designed for inverted roofing systems.

Benefits of inverted roof insulation:

  • Protects waterproofing membrane
  • High compressive performance
  • Compatible with green roof systems
  • Resistant to the passage of water vapour
  • Ideal for new build and refurbishment projects
