The DensDeck Prime Roof Board shall be neatly fitted to all roof penetrations and projections. No more boards shall be installed than can be covered with membrane and completed before the end of each day's work or before the onset of inclement weather.
The DensDeck Prime Roof Board can be applied over insulation boards, over existing roof surfaces and under adhered or mechanically attached single-ply roofing membranes. It must be installed using approved fasteners and plates or Firestone approved insulation adhesives.
The number of fasteners per board needs to be determined based on a wind uplift calculation in accordance with local building codes and taking into account a minimum requirement of 12 fasteners per board.
