Metal Roof Decks

Installation & Design Considerations

  • Evaluate climate and building interior conditions to determine the amount of roof deck insulation needed to control surface condensation on bar joists.
  • Wire-up installation: Utilize 16 or 18 gauge line wire run diagonally or perpendicular to insulation every 18 to 24 inches.
  • Impaling pin installation: Utilize impaling pins welded to the roof deck or fastened to the deck with adhesive. Impale insulation on anchor and secure with washer.
  • The minimum number of impaling pins needed are shown in the diagrams below. Pins should be placed 3”-8” from the edge(s) of the product.
