Projects - How to Insulate an Attic Floor with Foam it Green

Use Closed Cell Foam it Green for Attic Floors

Attic Insulation is an extremely common project. It's quick and easy to do. Plus the benefits range from much lower utility bills to reduced sound transfer.

By using closed cell Foam it Green, you create a seamless air barrier and high r-value that will keep your home much warmer than before in the winter and much cooler in the summer.

The rigid foam creates a pest barrier that helps keep insects and rodents out. And because it never sags or settles, once it's in place, it's done, unlike fiberglass. Plus, you're much less likely to have mold issues with the anti-microbial formula.

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 if
they exist. Also remove any preexisting
blown-in or batt
insulation, or move it to one half of
the attic, then repeating all
subsequent steps when one half is
completed. (Fig. 1)

3) Air seal penetrations around
chases, flues, and bypasses, which
includes junction boxes, lights, and
exhaust fans. (Fig. 2)

4) Air seal the furring cavity at the exterior wall (the gap between the exterior wall plaster and the brick bearing

4) Check attic access covers to make sure they are air tight. Install roof vent baffles to be used as insulation dams in
order to keep the soffit vents free and clear of foam or other insulation materials. (Fig. 3)

5) Apply Foam it Green in 1” cured layers to desired thickness, between the joists, sprayed to the attic deck or
backside of the ceiling material below. If using multiple insulation materials, roll out batt insulation over the foam,
or fill with blown in to desired R value.

6) If storage space is desired, construct a platform with joists running perpendicular to the attic’s, at a height tall
enough to accommodate the insulation’s ultimate total depth.
