How thick are the Invizimelt panels once installed?

Invizimelt panels have a finished installed height of ¼ inch. This low profile means metal roofing panels, membrane, and other roof coverings lay completely flat over the Invizimelt system with no visible ridges or bumps in the finished roof. The ¼ inch height also provides ample surface for nailing and screwing metal roof panels — installers do not need to work around fastener locations when installing the roofing material over the panels.
