Attic Insulation R Value Map

You ll see insulation r values indicated on product packaging and often on the product itself.

Attic insulation r value map.

R value is a measure of insulation s ability to resist heat traveling through it. How do you figure out r value. The amount and r value of your attic floor insulation depends on your geographical location zone. Colder climates will typically require a higher r value for even greater thermal.

Installing more insulation in your home increases the r value and the resistance to heat flow. Achieving greater r values in attics the higher the r value the better the thermal performance of the insulation. The r value or r value is a measure of thermal resistance ability to resit heat traveling through it used in the building and construction industry. Find your zone on the map and then use the chart to determine the level of insulation you need to properly insulate your attic walls floors and crawlspaces.

When calculating the r value of a multilayered installation add the r values of the individual layers. The higher r value the better insulation performance. R stands for resistance to heat flow. Recommended home insulation r values.

The greater the r value the greater the insulating performance. The higher the r value the better the thermal performance of the insulation. Install insulation with the proper r value. Your home s r value score will guide you toward the type of insulation you need.

Insulation is identified and labeled by r value. R value requirements are different based on your location. The higher the insulation r value the greater the insulating power. In general an attic s r value should be between r 30 and r 49.

R value refers to the insulation s ability to resist heat flow. In particularly cold climates you might go up to r 60.
