Insulation Standoff at Hangers and Supports

Insulation, Liner, Vapor Barrier & Condensation⚠️ VERIFYField workflow

Core Answer

Provide the approved support detail so insulation and vapor barrier are not crushed, cut, or left discontinuous at rods, straps, saddles, and trapezes.

What to Check First

Confirm whether the duct is lined, wrapped, or externally insulated
Use the specified saddle, shield, spacer, insulation insert, or standoff detail
Keep sharp strap/strut edges from cutting the jacket
Maintain vapor-barrier continuity and seal penetrations
Check that the support still carries the duct—not just soft insulation

Ask Foreman

At this hanger, what saddle or standoff detail keeps the insulation thickness and vapor barrier intact without losing support?

Text to Foreman

Do Not Do This

Do not cinch narrow wire, strap, or bare strut through soft insulation until the jacket and insulation are crushed.

Why This Matters

Compressed or torn insulation creates thermal bridges, condensation points, and damaged vapor barrier.

Verify against: project insulation and hanger details, insulation manufacturer instructions, foreman direction.
