PART 3 - EXECUTION
3.1 EXAMINATION
��� A.� Verify that building structure and building systems such as electrical conduit to be concealed are completed and approved.
��� B.� Correct any unsatisfactory conditions before proceeding.
3.2 ROOF INSULATION INSTALLATION
��� A.� Steel Straps:
������� 1.� Cut straps to length and install in the pattern and spacings indicated on shop drawings.
������� 2.� Tension straps to required value.
��� B.� Vapor Barrier Fabric:
������� 1.� Position pre-folded fabric on the strap platform along one eave purlin.
����������� a.� Clamp the two bottom corners at the eave and also centered on the bay.
����������� b.� Pull the other end of the pleat-folded fabric across the building width on the strap platform, pausing only at the ridge to fasten the straps and fabric in position where plane of roof changes and to release temporary fasteners on the opposite ridge purlin.
����������� c.� Once positioned, install fasteners from the bottom side at each strap/purlin intersection.
����������� d.� Trim edges and seal along the rafters.
��� C.� Insulation:
������� 1.� Unpack, and shake to a thickness exceeding the specified thickness.
������� 2.� Ensure that cavities are filled completely with insulation.
������� 3.� Place on the vapor barrier liner fabric without voids or gaps.
������� 4.� Place top layer of insulation over and perpendicular to the purlins without voids or gaps, as roof sheathing is applied.
������� 5.� Place thermal block on top of purlins or bottom of purlins for retrofit work, if no other thermal break exists.
��� ��� 6.� Place new insulation between purlins at the required thickness for the R-value specified.
3.3 WALL INSULATION INSTALLATION
��� A.� Insulation:
������� 1.� Install thermal break to exterior surface of girts as wall sheathing is applied.
������� 2.� Ensure that cavities are filled completely with insulation.
������� 3.� Cut insulation to required lengths to fit vertically between girts.
������� 4.� Neatly position in place and secure to Fast-R hangers.
������� 5.� Fluff the insulation to exceed the specified thickness.
��� B.� Vapor Barrier Fabric:
������� 1.� Apply the vapor barrier fabric by clamping it in position over eave strap.
������� 2.� Once in position, install fasteners through the eave strap into each roof strap, permanently clamping the wall fabric between them.
��� C.� Straps:
������� 1.� Install vertical straps along each column and 5 feet 0 inches on center, maximum, fastening to each girt to retain system permanently in place.
��� D.� Seal wall fabric to the roof fabric, to the base angle, up the columns.
3.4 CLEANING
��� A.� Clean any dirt or exposed sealant from the exposed vapor barrier fabric.
��� B.� Remove scraps and debris from the site.�
