Scope
Cellular glass (Foamglas-type) insulation — preferred for cold/cryogenic service down to about −260 °C; non-combustible, closed-cell, water-impermeable.
Key requirements (8)
- Cellular glass thermal insulation — Foamglas™ class material.
- Closed-cell, 100% inorganic glass foam — non-absorbent (zero water uptake).
- Service temperature: –269 °C to +482 °C (cryogenic to hot service).
- Thermal conductivity: ~0.040 W/m·K at 24 °C; ~0.033 at –40 °C.
- Compressive strength: 414 kPa (Type II), 690 kPa (Type IV) — load-bearing capable.
- Density: ~120 kg/m³.
- Default cryogenic insulation under cellular glass-cellular glass joints; resists liquid water ingress.
- Non-combustible per ASTM E136.
Note
Default cold-service insulation for cryogenic LNG / ethylene / ammonia and cold-box applications.
