5.9 GENERAL STEEL ROOF INSULATION
Pre-cut roof insulation to reach from eave to eave allowing approximately 2 feet of additional length to facilitate handling. Hold Insulation at one sidewall and roll out insulation across the purlins, vapor barrier to the inside of the steel building. Stretch the Insulation to provide a tIght and smooth inside surface. Weights clamped to each end can be used to hold insulation taut.
NOTE:
Insulation has no load bearing strength. Maintain body weight on approved scaffold or walk boards.
Double sided tape or contact adhesives can be used to hold insulation in place while the roof sheets are being installed. Trim excess insulation to the edge of the eave trim and cut fiberglass approximately 4 inches from end leaving only facing. Fold facing over end of blanket insulation to seal the ends.
NOTE:
Double sided tape and patch tape are supplied by erectors.

NOTE:
Do not install more insulation on roof than can be covered by roof panels before work period ends. Do not allow insulation to get wet.
A four foot starter roll of insulation is recommended to maintain the insulation joint ahead of the sheeting edge. Seal insulation sidelap joints with adhesives or fold and staple per manufacturer’s instructions. As on the walls, the general sequence is to install the roof sheets in conjunction with the insulation.
The insulation sidelap must be sealed to prevent condensation and minimize temperature loss at laps.
NOTE:
Wipe oil and other slippery substances from roof panels. Do not step on rib of panel, near a crease in the panel, near the side edge, or within 5-feet of unsecured panel.
