5. Cut the specified rigid insulation to size. The insulation should fit tightly into the framed opening. The edges of the insulation may be cut slightly angled to
assist with insertion into the opening.
6. Insert the insulation onto the impaling pins into the opening so that the insulation is flush with the back of the mullion.
7. Clean the surfaces of the mullion where the foil scrim tape will be applied with an approved solvent or cleaner.
8. Apply foil scrim tape to the four edges of the insulation and mullions to form an air tight seal. If the insulation is in more than one piece, tape the edges
together. See Figures 33, 34 and 35.
9. Insert the self locking washers onto the impaling pins and force them down to the surface of the insulation to hold the insulation securely. Fold the exposed
end of the impaling down, flush with the insulation, and apply foil scrim tape to cover the pin and washer completely. See Figure 36.
