Tape for ventilation duct joints must be selected with the metal surface, joint geometry and project specification in mind.
Check the specification
Duct type, temperatures and applicable standards depend on the application. Verify that required certifications belong to the selected tape and cover its intended use.
Apply and inspect
Prepare the surface as directed by the manufacturer and select width and overlap according to project requirements. Inspect the finished joint for wrinkles, gaps and lifted edges.
