PART 3 EXECUTION
3.1 INSTALLATION
A. Install insulation in accordance with manufacturer's
instructions.
B. Field-forming of pockets in insulation is not permitted.
C. Install insulation, parallel to roof slope and
perpendicular to purlins, progressing from eave to ridge.
NOTE ** Delete the following paragraph if project
conditions require left to right installation, or
left to right installation in addition to right to
left installation. "Opposite side" ConSealTab
rolls will be required for left to right
installations.
D. Install insulation rows beginning from right to left.
E. Roll out insulation using pipe or other device inserted
through cardboard core of insulation roll as spindle;
ensure that exposed tab trails direction of progress.
NOTE ** Delete the following paragraph if thermal blocking
not required.
F. Place thermal blocks at end-to-end butt joints, covering
joint a minimum of 4 inches (101 mm) each side of joint.
G. Adjust each row of insulation to lay flat across purlins.
H. As each successive row of insulation is placed, snug roll
against previous row, pulling up exposed tab between the
two rows.
I. Beginning at end of row, pull back long edge of batt on
previous row, allowing exposed tab to fall into place;
smooth exposed tab down against facing from previous row,
ensuring that tab lays flat, then drop batt from previous
row back into place, ensuring that batts are snug against
each other.
3.2 PROTECTION OF INSTALLED PRODUCTS
A. Do not allow exposure of installed insulation to
moisture; install only the quantity of insulation in a
single period of construction activity that will be
covered by roofing in that period.
