Cellular Glass Insulated Pressure Vessels
Cellular glass insulated pressure vessels utilize rigid closed-cell glass foam insulation to provide thermal protection with exceptional moisture resistance and compressive strength. Cellular glass is manufactured by foaming molten glass to create a rigid, waterproof insulation material with completely closed cells that prevent moisture absorption.
Why Choose Cellular Glass for Pressure Vessel Insulation?
Cellular glass insulation is specified when both thermal performance and complete moisture impermeability are required. Its closed-cell structure makes it ideal for cold service applications where condensation and moisture intrusion can compromise insulation performance. Cellular glass also provides excellent compressive strength and dimensional stability.
Cellular Glass Insulated Pressure Vessel Applications
Common applications include:
- Cryogenic and cold service vessels
- Underground and buried piping
- Refrigerated storage facilities
- Chemical plant equipment
- Vessels subject to moisture exposure
- Applications requiring vapor barriers

Cellular Glass Insulated Pressure Vessel Frequently Asked Questions (FAQs)
What makes cellular glass unique among insulation materials?
Cellular glass is the only insulation material that is completely impermeable to water and water vapor due to its 100% closed-cell glass structure. It cannot absorb moisture under any conditions, including immersion, making it ideal for below-grade, high-humidity, and cold service applications where moisture control is critical.
When should cellular glass be specified over other insulation?
Specify cellular glass when moisture impermeability is essential (underground, below-grade, high humidity), when dimensional stability under load is required, when non-absorbent insulation is mandated, or when the application involves both cryogenic temperatures and potential moisture exposure. Its unique properties justify premium cost in demanding applications.
How is cellular glass installed on pressure vessels?
Cellular glass is installed using adhesive and mechanical fasteners as needed. Joints are sealed with compatible adhesive or hot-applied sealant to maintain the continuous moisture barrier. The rigid blocks and segments are easily fabricated to fit vessel contours. Protective jacketing provides mechanical protection for the cellular glass system.
