Projects - How to Insulate Attic Rafters with Foam it Green
Use Closed Cell Foam it Green for Attic Rafters
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 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.
