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.

Insulation is identified and labeled by r value. Achieving greater r values in attics the higher the r value the better the thermal performance of the insulation. How do you figure out r value. Installing more insulation in your home increases the r value and the resistance to heat flow.

R value refers to the insulation s ability to resist heat flow. Colder climates will typically require a higher r value for even greater thermal. 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. In general an attic s r value should be between r 30 and r 49.

When calculating the r value of a multilayered installation add the r values of the individual layers. Install insulation with the proper r value. In particularly cold climates you might go up to r 60. The r value of some insulations also depends on temperature aging and moisture accumulation.

The greater the r value the greater the insulating performance. The amount and r value of your attic floor insulation depends on your geographical location zone. Recommended home insulation r values. The higher r value the better insulation performance.

R value is a measure of insulation s ability to resist heat traveling through it. R stands for resistance to heat flow. The higher the r value the better the thermal performance of the insulation. Insulation level are specified by r value.

R value requirements are different based on your location. 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.
