How thick is R30 faced insulation?

A: Hello Alexa, Owens Corning R-30 insulation is 9.5″ thick. We would not recommend compressing this product into a 3.5″ cavity as it will reduce its R-value. Please note the kraft facing is flammable and needs to be covered by a 15 minute thermal barrier such as 1/2″ drywall.

Should I use faced or unfaced insulation in my attic?

Faced Insulation: If the attic doesn’t have any existing insulation, use faced insulation with the paper facing toward the heated living space. Unfaced Insulation: When adding more insulation to an attic that already has insulation, use unfaced insulation.

What is r30 insulation used for?

A wall is R-19, a roof is R-30 — what does this mean? Essentially R-value is a measure of thermal resistance, or the ability to prevent the transfer of heat. The larger the number, the harder that insulation is working at preventing heat conduction. The less heat loss, the lower your energy bills.
