Condensation Appears Above Freezer or Refrigerated Aisles
Find the cold surface and the break in the thermal or vapor-control system before patching the visible drip. Check insulation continuity, vapor-barrier damage, air leakage, compressed insulation, wet material, and local humidity conditions.
The sweating is concentrated at this collar above the freezer aisle. I checked the nearby wrap and found a vapor-barrier break plus exposed metal at the fasteners. Do you want the insulation repair reviewed before we close the area?
Watch out
Do not cover active sweating with more tape or insulation until the source is identified.
Check
Trace the moisture to the exact duct, collar, damper, access frame, support, or penetration.
Inspect insulation thickness and continuity around fittings and hardware.
Check vapor-barrier seams, punctures, crushed areas, and wet insulation.
Check for duct leakage or water intrusion before repairing the jacket.
