Place the 1st section of Reflecto-Pan “HVRC” as follows:IMPORTANT INFORMATION:
a) Install Reflecto-Pan “HVRC” (print side is out or down) centered between joists & 2” or more past the top side of the duct. This provides for a tight seal when final trunk has been installed.
b) Staple side tabs to the bottom of the joists using a minimum 3/8” staple every 2”, insuring that the print side is out or down. (Also approved attachment methods; steel staples, sheet metal screws, roofing nails)
a) Install Reflecto-Pan “HVRC” (print side is out or down) by scoring 1” lip across the end of the panel and bend down 90 degrees.
b) Center Reflecto-Pan “HVRC” between the bottom of joist. Butt it tightly to existing trunk, beam or plate.
c) Tape seams with an aluminum tape or UL181 aluminum.
d) Staple side tabs to the bottom of the joists using a minimum 3/8” staple every 2”, insuring that the print side is out or down. (Also approved attachment methods; steel staples, sheet metal screws, roofing nails)
a) Butt leading edge of sheet to the to next butt edge of sheet tightly.
b) Staple and tape seams as before (described above).

1. In the 20003 International Mechanical Code Commentary - Section 602.3; Sheet Metal has traditionally been used for both stud cavity and joist space plenums. Code does not specify types of materials allowed for panning the bottom of open joists to create joist plenums. Traditionally, sheet metal has been used, however, composite materials have and are used.
2. Check your local codes before installation for compliance in your area.
