What is used to seal joints between panels in a PEB installation?

Explanation:
Sealing joints between panels in a PEB uses a flexible sealant that fills the gap, bonds to metal, and stays elastic to accommodate movement. This keeps out water and air and lasts through temperature changes without cracking. Nails only fasten panels and don’t seal gaps, leaving openings for leaks. Paint sits on the surface and won’t seal the joint or handle movement. Glue would try to bond the panels but isn’t designed to tolerate the joint movement and moisture in metal panel systems. So the best choice is sealants.
