Examine steel decks to assure that panels are properly secured to structural members and to each other and that surfaces of top flanges are flat or slightly convex, and are without stiffening grooves.

3.2 APPLICATION

Keep roof insulating materials dry before, during and after installation.

Keep insulation 12 millimeters clear of vertical surfaces penetrating and projecting from the roof surface.

3.2.1 Vapor Barrier

Install vapor barrier in direct contact with concrete deck surface.
