Attic Insulation R Value Map

R stands for resistance to heat flow.

Attic insulation r value map.

The amount and r value of your attic floor insulation depends on your geographical location zone. R value requirements are different based on your location. Install insulation with the proper r value. The table below shows what levels of insulation are cost effective for different climates and.

The higher the r value the better the thermal performance of the insulation. When calculating the r value of a multilayered installation add the r values of the individual layers. In general an attic s r value should be between r 30 and r 49. Colder climates will typically require a higher r value for even greater thermal.

Insulation is identified and labeled by r value. 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. R value refers to the insulation s ability to resist heat flow. The higher the insulation r value the greater the insulating power.

Insulation level are specified by r value. Recommended home insulation r values. Achieving greater r values in attics the higher the r value the better the thermal performance of the insulation. You ll see insulation r values indicated on product packaging and often on the product itself.

Your home s r value score will guide you toward the type of insulation you need. R value is a measure of insulation s ability to resist heat traveling through it. Installing more insulation in your home increases the r value and the resistance to heat flow. The higher r value the better insulation performance.

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 particularly cold climates you might go up to r 60.
