1) Follow all of the instructions in the included
instruction manual regarding proper Foam it Green
setup, project area preparation, and substrate readiness.
Make sure that you have all of the tools required for the
job (see Tools).

2) Remove attic floor boards only if/as needed to locate
and air seal the furring cavity at the exterior wall (the
gap between the exterior wall plaster and the brick
bearing wall).

3) Install rigid insulation transition piece from top of
wall to underside of roof sheathing. (Fig. 1)

4) Apply closed cell foam to all seams of rigid boards
used as transition piece including at connections to attic
deck, roof deck, and adjacent rigid insulation pieces.
(Fig. 2)

5) Install rigid insulation to cover ridge vent, applying
closed cell foam to seal in place.

6) Apply closed cell foam to roof deck in 1” cured
layers to desired thickness. (Fig. 3)

*Please note, roof vent baffles can be used behind rigid insulation pieces as well as under spray foam, run along the
underside of the roof decking to the ridge vent, to allow for air movement from soffits to ridge. This creates an air
gap under the roof decking. Spray foam can be applied directly to the roof vent baffles to desired thickness.
