N Deck (3" Roof Deck)

N Roof Deck (3″ Roof Deck) is a 32″ net coverage structural decking product. Roof deck is the structural substrate for the roof waterproofing membrane and acts as a structural element resisting both vertical and lateral (horizontal) loads. Available with an interlocking side lap for DeltaGrip® DG4™ installations.

The Delta Grip system is an innovative pneumatic side lap attachment tool that increases installation ease and speed. This system provides high diaphragm shear capacities similar to top seam weld installations, but with the cost equivalent of button punching.
