Urethane & Cryogenic Pipe Insulation
Rigid Urethane Board / PIR · PUR Board
Cryogenic −196°CCold store standardBest value insulationHigh compressive strength
Service temperature
Ambient−196°C to +80°C
Main applications
Rigid PUR foam boardλ = 0.021–0.024 W/mK−196°C to +80°C
- for building external insulation
- cold stores and cryogenic plant
- maximum insulation from minimum thickness at the best value available
Key Features
💰
The best-value insulation board
Rigid PU foam — less thickness and lower installed cost than XPS or EPS for the same insulation performance
🌡️
Low conductivity (λ ≈ 0.022–0.028)
Rigid polyurethane foam — more than twice the performance of expanded polystyrene, giving high efficiency at low thickness
🧱
High compressive strength
The rigid foam structure has high compressive strength, allowing use in loaded floor insulation
✂️
Easy to work on site
Cut easily with a knife or power saw — trimmed to fit on site
📦
A range of thicknesses and sizes
From 10T to over 200T in a range of board sizes — covering building and industrial applications alike

Applications
Building insulation
- •Insulation board for walls, roofs and floors
- •Base insulation in external wall systems
Refrigeration & cold storage
- •Core material for cold store panels
- •Internal wall insulation board in refrigerated plant
Industrial plant
- •External insulation board for tanks and vessels
- •Insulation casing for industrial equipment
Refurbishment
- •Reinforcing wall insulation in existing buildings
- •Insulation board between floors
Notes
- ※Where a fire rating is required, specify PIR board instead — standard PU is combustible, so take care in environments needing a semi-non-combustible rating.
- ※Prolonged UV exposure yellows the surface — an external finish is needed where the board is exposed outdoors.
