Material selection

Compare insulation jacket materials by service

Choose the facing, core and closures together. Specify equipment surface temperature, access, moisture and any required thermal or cleaning performance.

Silicone-coated glass-fibre facing

Role in the assembly: Outer or inner facing where the assembly rating permits
Where to consider it: Dry indoor hot service and general-purpose valve or flange jackets
What to check: Compare coating temperature, abrasion and stitch-seam exposure. Ask for data for the specific coating and fabric.

PTFE-coated or laminated glass-fibre facing

Role in the assembly: Facing for selected wet, chemical or washdown conditions
Where to consider it: Applications where cleaning chemistry and seam detailing drive selection
What to check: Confirm chemical compatibility, seam and closure construction, and any site-specific hygienic approval for the complete cover.

Mineral fibre or needled glass-fibre core

Role in the assembly: Fibrous thermal core
Where to consider it: Dry hot equipment with room for the required thickness
What to check: Compare conductivity at design temperature, bulk, compression and handling. Request separate core data for each proposed material.

Aerogel blanket core

Role in the assembly: Thin-profile alternative for clearance constraints
Where to consider it: Locations where conventional build-up interferes with access or adjacent services
What to check: Compare total installed thickness, seams, handling and price against a conventional core at the same thermal objective.

Closed-cell elastomeric insulation

Role in the assembly: Core for selected chilled-water systems
Where to consider it: Condensation control where a continuous vapour seal can be maintained
What to check: Check minimum and maximum service temperatures, ambient dew point and the joint seal after repeated removal.

Silica or ceramic hot-face fabric

Role in the assembly: Hot-face layer for selected higher-temperature designs
Where to consider it: Process heaters or extrusion zones where documented surface temperatures call for it
What to check: Review the entire assembly: core, cold face, seams, thread and fasteners can have different limits.

Compare thickness at the same objective

For dry hot service, a nominal 25 mm fibrous core can be a starting point for a comparative quotation. Compare alternatives against the same heat-loss or outer-surface target and the same operating conditions. For chilled water, calculate against dew point and check how the vapour seal is restored after servicing.
