If your metal building insulation is torn, sagging, wet, or falling apart, this video shows a complete, professional-grade system to restore it like new — without removing the old insulation. The BlueTex method creates a new internal vapor barrier, stops condensation, and upgrades both the performance and appearance of any aging metal building. Metal building insulation repair has never been simpler!
Stop Condensation Before It Ruins Your Metal Building
The video dives into the biggest problem with damaged metal building insulation: moisture and condensation. When the original vinyl-facing gets torn, humid air reaches the cold metal panels, causing water droplets, rust, mold, and soaked insulation. The BlueTex system seals the interior so moisture can’t reach the metal skin.
The Three Components of the Metal Building Insulation Repair System
The supplies needed for this installation are:
- BlueTex Pro (50” wide) — a tear-proof, puncture-resistant foil/vapor barrier that instantly makes the interior look finished and clean.
- Custom extruded aluminum Termination Bars (TermBars) — secure the BlueTex tightly to the purlins.
- BlueTex 3″ Vapor Barrier Seam Tape — seals every seam for an airtight, moisture-resistant finish.
This combination creates a durable airtight vapor barrier that prevents warm, moist air from reaching cold metal surfaces.
Installation Overview
From layout to final sealing, the video shows:
- Getting started
- Creating an airtight system
- Installation prep including cutting, layout, and planning around obstacles
- Installing BlueTex Pro on ceilings and purlins
- Taping and sealing seams to maintain the vapor barrier
- Working around pipes, trusses, and braces
Every step ensures the final surface is tight, smooth, and condensation-proof.
Purlin Condensation & Connection Details
The video also explains how condensation forms on exposed purlins and how to properly attach BlueTex with TermBars. The secure mechanical connection not only tightens the vapor barrier but also adds strength and a clean, finished look.
Walls, Finishing, and Restoring Old Buildings
See how to:
- Install BlueTex on walls over old insulation
- Paint exposed purlins for a fresh, uniform interior
- Renovate old, damaged, or poorly insulated metal buildings
The transformation is dramatic — turning a deteriorated interior into a bright, clean, modern look while fixing condensation problems permanently.
Repair Tape
The BlueTex 6″ Wide Repair Tape is also featured, as it is for patching small holes and sealing your bigger seam areas.
