METAL INSIDE CLOSURE

1/4"-14 X 1" (2) PER INSIDE CLOSURE

Using 1/4"-14 x 1" fasteners, attach the first inside closure to the eave strut, locating the face of the inside closure with the steel line. Note that the first inside closure must be field cut in half to fill the void under the partial rib near the rake support. Apply Tri-Bead tape mastic to the bottom of each inside closure with an additional 1/2" at each side. Locate additional closures on 24" centers from the first closure to maintain panel module, attaching each with 1/4"-14x1" fasteners. Install two fasteners per closure. The first fastener should be installed through the slotted hole to allow for any adjustment that may be required. To maintain panel module, metal inside closures must be installed on 24" centers. Measure from tab to tab located on the metal inside closure. Apply Tri-Bead tape mastic to the trim cap and over the top and sides of each closure to complete the seal at the eave. Roll out insulation from eave to peak, laying the side of the insulation on top of the rake support. The first roll should be 3' wide. This will keep insulation side laps 1' from panel side laps. Allow approximately 4" of insulation to hang past the double faced tape (down slope) before sticking the insulation to the double faced tape. Cut and remove the fiberglass, approximately 4", and fold the vapor retarder back over the insulation (upslope).
