VAPOR-STOP & SEALING SYSTEMS

Vapor barrier integrity is critical for cryogenic and cold applications.
Moisture ingress leads to corrosion under insulation (CUI) and system degradation.

Typical intervals between vapor stops range 3 – 6 m, or at each break in continuity (flanges, supports, instruments, terminations).

Common systems:

• Pittseal 444N – Two-part mastic for FOAMGLAS® applications.

• Foster 90-66 – Flexible vapor-stop coating for cold lines.

• ArmaFlex 520 – Single-component contact adhesive for FEF joints.

• ULVA Plastic Lagging – UV-stable protective jacketing for outdoor use.

CLADDING & OVERLAPS

• Typical jacketing: 0.5 mm Al with PSMB or 0.4 mm stainless steel; heavy-duty areas use 0.7–1.2 mm gauge.

• Overlap rules: 50 mm on straight runs, up to 75 mm on large diameter elbows.
  Small diameter “fish-scale” fittings typically lock mechanically (3–5 mm overlap).

• Expansion joints: typically 15–20 m for moderate systems, 6–10 m for high ΔT — determined by thermal expansion calculation.

QA/QC & INSTALLATION PRACTICES

• Focus areas:

  • Stagger longitudinal joints, avoid cross-seams.

  • Offset multilayer joints ≥ 50 mm.

  • Continuous vapor-stop coverage at supports and fittings.

  • Clean surface preparation before cladding.

  • Inspection points logged per ITP.

Quadra Tech follows ISO 9001 and project-specific QA requirements.

PRACTICAL INSTALLATION TIPS

• Always stagger longitudinal joints.

• Avoid cross-seam alignment (four corners must never meet).

• Apply vapor-stop mastics at every support and penetration.

• Verify alignment before cladding closure.

• Mark inspection seams for QA confirmation.

COMMON ISSUES & FIELD AUDITS

Common issues:

• Misinterpreted staggering (aligned cross-seams).

• Incomplete vapor-stop coverage at fittings.

• Wrong cladding overlap direction → water ingress.

• Incompatible adhesive/material pairing.

• Improper support spacing → deformation.

Field audits:
Quadra Tech offers independent on-site audits and technical evaluations for EPC and QA/QC teams.
