Question: Can we put foam board over the plywood?
Rebecca writes from Tucker, Georgia: "We put down plywood over blown-in insulation in our attic for extra storage space. Can we put the F150 foam board over the plywood to help increase the R value?"
Answer: Yes, you can put FOAMULAR® 150 insulation board down over the plywood. It is not a common or recommended application, but you can do it. You may want to check your local building code. The code may require FOAMULAR insulation to be covered with a fire-rated material.
