what is blackboard insulation

Some builders use 1/2-inch wood sheathing (R-0.6) or asphalt impregnated sheathing, usually called blackboard (R-1.3) to sheath the walls. By using a 1/2-inch foam insulated sheathing (R-2 to R-3.5) in combination with wall cavity insulation, the total R-value of the exterior wall will be increased, contributing to greater energy efficiency.

What is Insulation R-Value?

Insulation ratings are measured in R-values per inch of thickness. An R-value tells you how well a type of insulation can keep heat from leaving or entering your home. Insulation R-values vary based on the type, thickness and density of the insulation material.

R-Value U.S. Map

Your home doesn’t necessarily need the highest R-value insulation. The R-value your insulation needs depends on your local climate.

R-Value Insulation Chart

Find your zone on the map and then use the above insulation R-value chart to determine the level of insulation you need to properly insulate your attic, walls, floors and crawlspaces. These R-values are a sum, meaning this should be the total R-value once you add up the entire depth of insulation.

Achieving Greater R-Values in Attics

Insulation ratings can be improved by adding more layers of insulation. You can mix the type and material of insulation too. For example, if your attic already has fiberglass insulation blankets installed, you can improve its R-value by installing blown-in cellulose insulation on top of the blankets.

Achieving Greater R-Values in Exterior Walls

As with attics or anywhere else in your home, adding more layers of insulation to your exterior walls is key to having a higher R-value and better thermal performance. Foam board insulation is easy to install between wall studs and over existing blanket insulation. Seal gaps around windows and doors with spray foam insulation.

Other Areas to Insulate

In addition to attics and exterior walls, you can get greater R-values for your home by remembering to insulate these areas as well:
