Proper design and installation of vapor barriers and ventilation systems are important to prevent condensation and the resulting
problems of moisture damage and loss of insulation efficiency.
Condensation occurs when moisture laden air comes in contact with a surface temperature equal to or below the dew point
of the air. This phenomenon creates problems that are not unique with metal roofing; these problems are common to all
types of construction.
The underside of the metal roof on a typical Architectural building should be protected from condensation by installing
panels directly over a minimum 30 lb moisture barrier and uniform solid substrate. This reduces airspace and the potential of
condensation forming on the underside of the panels.

PANEL APPLICATIONS
The following chart highlights UL 580 Class 90 for clip installation on the selected applications (see Fastener Selection Guide
page PGI-12-14 for other fasteners available). For more information on UL Construction numbers, refer to UL Roofing Materials
and System Directories.
* Length of Deck Screw will vary depending on the total thickness of the rigid insulation and metal decking.
** Based on UL-580. Subject to project loading, closer clip (fastener) spacing may be required. Contact your local Metal
Sales branch representative for more information (see pages 2 and 3).
