Attic Insulation R Value Map

How do you figure out r value.

Attic insulation r value map.

The higher the r value the better the thermal performance of the insulation. The table below shows what levels of insulation are cost effective for different climates and. R value refers to the insulation s ability to resist heat flow. Recommended home insulation r values.

R value requirements are different based on your location. Achieving greater r values in attics the higher the r value the better the thermal performance of the insulation. Insulation level are specified by r value. Install insulation with the proper r value.

You ll see insulation r values indicated on product packaging and often on the product itself. In particularly cold climates you might go up to r 60. 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. The amount and r value of your attic floor insulation depends on your geographical location zone.

In general an attic s r value should be between r 30 and r 49. R value is a measure of insulation s ability to resist heat traveling through it. The higher r value the better insulation performance. The greater the r value the greater the insulating performance.

Installing more insulation in your home increases the r value and the resistance to heat flow. 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. Colder climates will typically require a higher r value for even greater thermal. When calculating the r value of a multilayered installation add the r values of the individual layers.

Your home s r value score will guide you toward the type of insulation you need. The r value of some insulations also depends on temperature aging and moisture accumulation.
