Material | Advantages | Products |
|---|---|---|
Vacuum Insulation Panels (VIPs) | Suited to applications where there may be a requirement for both low U-values and the thinnest possible roof build-up Problem solver for where a lack of construction depth or space is an issue Optimum performance with a declared thermal conductivity of just 0.007 W/mK Design service for your specific roof For use with most fully adhered single-ply waterproofing membranes | |
PIR | High performance insulation - thermal conductivities as low as 0.022 W/mK Fully compatible with most mechanically fixed single-ply waterproofing systems Compatible with most green roof systems Installation technique is ideal for fast track building programmes Easy to handle and install compared to some other commonly used insulants | Thermaroof TR24 - for use with partially bonded torch-applied multi-layer bituminous waterproofing Thermaroof TR26 - for use with mechanically fixed single-ply waterproofing Thermaroof TR27 - for use with fully adhered single-ply, partially bonded built-up felt, mastic asphalt and cold liquid applied waterproofing |
Rigid Extruded Polystyrene(XPS) | Ideal for car park decks High compressive strength withstands vehicle laods Minimal water absorption Withstands freeze/thaw cycling Easy to handle and install compared to some other commonly used insulants | Kingspan GreenGuard GG300 -compressive strength of 300 kPa Kingspan GreenGuard GG500 - compressive strength of 500 kPa Kingspan GreenGuard GG700 - compressive strength of 700 kPa |
Rock mineral fibre | A1 Euroclass Fully compatible with most mechanically fixed single-ply waterproofing systems
