50mm Kingspan OPTIM‑R E Vacuum Insulation Panel - OPTIM‑R E Inverted Roofing System is an ultra‑thin, high‑performance vacuum insulation system designed specifically for inverted flat roofs, where achieving very low U‑values is essential but build‑up height is restricted. The system uses OPTIM‑R E Vacuum Insulation Panels (VIPs) with an exceptional declared thermal conductivity of 0.008 W/mK, delivering insulation performance far superior to conventional inverted‑roof materials.

OPTIM‑R E VIPs are installed beneath the ballast layer (such as paving or gravel) and above the waterproofing membrane. Because VIPs cannot be cut on site, Kingspan provides a project‑specific layout, ensuring panels are placed only in safe zones. Areas where VIPs cannot be used — such as around roof penetrations, outlets, or upstands — are completed using Kingspan OPTIM‑R E Infill Panels, a rigid extruded polystyrene (XPS) insulation designed to maintain continuity of thermal performance across the roof. The result is a hybrid inverted‑roof insulation system that achieves maximum thermal efficiency with minimal thickness, ideal for refurbishments, heritage buildings, and new‑build projects with strict height limitations.

CHARACTERISTICS

  • Ultra‑low thermal conductivity — VIPs achieve 0.008 W/mK, enabling extremely low U‑values.
  • Minimal build‑up thickness — ideal for inverted roofs with limited height at parapets, thresholds or interfaces.
  • Hybrid system design — VIPs + XPS infill panels ensure full‑area insulation coverage.
  • Project‑specific layout — Kingspan provides a bespoke panel arrangement for each roof.
  • Moisture‑resistant — VIPs are highly resistant to water vapour transmission.
  • High compressive strength — suitable for inverted roofs under ballast or paving.
  • Durable and stable — designed for long‑term performance in exposed roof environments.
  • Certified performance — BDA Agrément certified for 20–50 mm VIP thicknesses.
APPLICATION

  • Inverted flat roofs — beneath ballast, paving slabs or green‑roof systems.
  • Refurbishment projects — where raising roof levels is not possible.
  • New‑build inverted roofs — achieving enhanced U‑values with minimal thickness.
  • Roofs with height constraints — heritage buildings, balcony interfaces, parapet‑limited roofs.
