Insulated metal panels (IMPs) rely on panel-to-panel joints to prevent leaks and air loss. This article reviews sealant, gasket, and mechanical strategies for performance and longevity.
Overview
IMPs feature interlocking joints that often include factory-applied gaskets and require jobsite sealant to complete the barrier. These joints must account for thermal movement, air pressure, and moisture control—especially in horizontal installations.
Joint Types and Protection
- Double tongue-and-groove joints: Allow offset gasketing and sealant application
- Factory-applied gaskets: EPDM or silicone options pre-bonded to panel edges
- Jobsite sealants: Non-skinning butyl or polyurethane for longevity
🔍 Quick Picks
- IMP Joint Sealant: Tremco Butyl Sealant
- Panel Gasket Tape: Closed Cell Gasket Tape Roll
- EPDM Flap Seal: EPDM Rubber Weather Seal Strip
Field Quality Considerations
Store panels in dry conditions and inspect gaskets prior to installation. Remove protective films just before setting panels. Always pressurize test assemblies if used in critical enclosures like clean rooms or cold storage.
Conclusion
Joints are the lifeblood of IMP performance. Select compatible sealants, inspect factory gasketing, and follow tested installation details to avoid failures in critical environments.
