50mm Kingspan OPTIM‑R Vacuum Insulation Panel - OPTIM‑R Roofing System - 600mm x 1200mm

50mm Kingspan OPTIM‑R Vacuum Insulation Panel - OPTIM‑R Roofing System is an ultra‑thin, high‑performance vacuum insulation solution designed for flat roofs where achieving very low U‑values is essential but build‑up height is severely restricted. The system uses vacuum insulation panels (VIPs) with an exceptional declared thermal conductivity of 0.007 W/mK, enabling thermal performance far beyond conventional rigid insulation boards.

VIPs are installed according to a project‑specific layout plan, ensuring panels are positioned only in safe zones (no fixings, no penetrations). Areas where VIPs cannot be placed - such as around outlets, upstands, rooflights, or service penetrations - are completed using Kingspan OPTIM‑R Infill Boards, a rigid phenolic insulation that maintains continuity of thermal performance across the roof. The result is a hybrid roofing insulation system that delivers maximum thermal efficiency with minimal thickness, ideal for refurbishments, heritage buildings, and new‑build projects with strict height limitations.

CHARACTERISTICS

• Vacuum insulation performance - declared thermal conductivity 0.007 W/mK, among the lowest available. 
• Ultra‑thin build‑ups - ideal for roofs with restricted parapet heights or limited upstand allowances.
• Hybrid system design - VIPs + phenolic infill boards ensure full‑area insulation coverage.
• High thermal efficiency - enables very low U‑values even where standard insulation cannot be used. 
• Resistant to water vapour passage. 
• VIPs are over 90% recyclable by weight. 
• High compressive strength - suitable for warm‑roof build‑ups under membranes.
• Certified performance - BDA Agrément certified for 20–50 mm thicknesses. 
• Non‑deleterious material - safe for use in all building types.

• Warm‑roof systems - beneath waterproofing membranes.
• Flat roof refurbishments - where raising roof levels is not possible.
• New‑build flat roofs - achieving enhanced U‑values with minimal thickness.
• Roofs with height constraints - heritage buildings, parapet‑limited roofs, balcony interfaces.
