The ArmaGel® Family: Complete Aerogel Insulation Solutions for Extreme and Cyclic Conditions
Modern industrial insulation is judged on more than thermal conductivity. Corrosion under insulation (CUI), vapor control, thermal cycling fatigue, cryogenic contraction, fire compliance, structural constraints, and lifecycle economics all shape the specification. The ArmaGel® family gives engineers five platforms to match against those demands.
Why aerogel insulation?
Aerogel delivers significantly lower thermal conductivity than mineral wool, PIR, or cellular glass. In practice that means reduced thickness at equivalent thermal performance, lower structural loading with simplified support systems, a hydrophobic structure that repels water and mitigates CUI, and improved lifecycle economics through easier maintenance.
The ArmaGel® portfolio by thermal regime
ArmaGel® HTL — high-temperature, non-combustible (up to 650°C)
For sustained elevated-temperature applications requiring a non-combustible classification. Typical use cases include refinery piping, petrochemical processing, power generation, and fire-critical environments.
ArmaGel® HT — high-temperature efficiency with reduced thickness
Optimized for systems up to 650°C where thickness reduction matters: offshore and onshore oil & gas, process facilities, industrial pipework, and acoustic systems.
ArmaGel® DT — dual-temperature cyclic systems
Engineered for systems that cycle above and below ambient. DT addresses thermal expansion fatigue, intermittent condensation, process variability, and cycling-induced CUI. Common uses include batch processing, seasonal operations, and mixed-temperature lines.
ArmaGel® XGC — cryogenic and extended dual-temperature (−180°C to +250°C)
Developed for LNG, industrial gas, and extreme low-temperature service. XGC features an integrated zero-perm vapor barrier, cryogenic flexibility, and an ultra-thin profile. Industries served: LNG terminals, cryogenic storage and transfer, offshore platforms, and gas processing.
ArmaGel® Rail — rail-compliant aerogel insulation
Designed for rolling stock that has to balance fire safety, passenger comfort, and efficiency. EN45545 HL3 compliant, with an integrated vapor barrier, enhanced acoustics, and minimal thickness.
Specifying ArmaGel®: a performance-based selection framework
Selection should align with system behavior and risk exposure rather than temperature rating alone.
1. Define the thermal operating envelope
- Sustained elevated temperature (up to 650°C): select HTL where non-combustibility is required; choose HT where thickness reduction and efficiency are the primary drivers.
- Cryogenic or sub-zero service: select XGC, particularly where a zero-perm vapor barrier is required to mitigate moisture ingress, ice formation, and corrosion.
- Dual-temperature or cyclic systems: select DT for repeated thermal transitions, addressing thermal fatigue, dimensional stability, condensation control, and long-term CUI.
2. Evaluate vapor drive and moisture exposure
- Cryogenic service → XGC (integrated vapor barrier)
- Rail applications → Rail (integrated vapor barrier)
- Cyclic industrial systems → DT (moisture-resistant structure)
- Elevated temperature → HTL / HT (hydrophobic protection)
3. Assess fire and regulatory requirements
- Non-combustible classification → HTL
- Industrial fire-classified → HT / DT
- Rail EN45545 HL3 → Rail
4. Consider structural and thickness constraints
Where thickness affects support spacing, jacketing, retrofit clearance, or structural load: HT for high-temperature thickness reduction, XGC for cryogenic thickness reduction, and Rail for rail weight optimization.
5. Incorporate lifecycle risk
Specification decisions should account for maintenance removal complexity, inspection accessibility, downtime cost exposure, corrosion mitigation, and system reliability under cycling. ArmaGel systems are often selected where shutdown costs and corrosion remediation risk run high.

Frequently asked questions
Which ArmaGel® grade handles cryogenic service?
ArmaGel® XGC is rated to −180°C with an integrated zero-perm vapor barrier, developed for LNG, industrial gas, and extreme low-temperature service.
What makes DT different from HT?
DT is engineered for systems that cycle above and below ambient — thermal fatigue, condensation control, and cycling-induced CUI — while HT targets sustained elevated temperature up to 650°C with reduced thickness.
