	** NOTE TO SPECIFIER ** Porvene Doors, Inc.; industrial, commercial, service doors, coiling grilles and insulated rolling doors. . This section is based on the products of Porvene Doors, Inc., which is located at: 14241 Grant St. Moreno Valley, CA 92553 Tel: 877-906-3999 Fax: 877-343-6677 Email: request info Web: www.porvenedoors.com [ Click Here ] for additional information. 200 Series: This product can be insulated, wind locked, and built with a pass door. The complete line is available, depending on size, as hand operated or chain operated and can be upgraded to electric operation. . 300 Series: Offers the economy of a sheet door with the added strength of a service door. Available with 22 or 24 gauge steel slat curtain (some sizes available only in 24 gauge) and can be wind locked. . 400 Series: Offers 24, 22, 20 and 18 gauge slats for additional strength. Our new and innovated slat design reduces the snapping sounds that come from metal to metal contact common to rolling steel slat doors when opening and closing. . 500 Series: Coiling grille constructed using aluminum tubes over solid steel rods giving added strength for security and features low friction nylon blocks mounted to the bottom bar for quiet operation. . 600 Series: Offers insulating values of R-Factor = 5.4 and U-Factor = 0.185. The insulation material is made from environmentally safe Polyisocyanurate with aluminum facers adhered to the effective thermal barrier.
