Attic Insulation R Value Map

In general an attic s r value should be between r 30 and r 49.

Attic insulation r value map.

Colder climates will typically require a higher r value for even greater thermal. Install insulation with the proper r value. The higher r value the better insulation performance. Insulation level are specified by r value.

The greater the r value the greater the insulating performance. The r value of some insulations also depends on temperature aging and moisture accumulation. R value is a measure of insulation s ability to resist heat traveling through it. The table below shows what levels of insulation are cost effective for different climates and.

Recommended home insulation r values. The amount and r value of your attic floor insulation depends on your geographical location zone. The higher the r value the better the thermal performance of the insulation. R value refers to the insulation s ability to resist heat flow.

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. R stands for resistance to heat flow. Your home s r value score will guide you toward the type of insulation you need.

When calculating the r value of a multilayered installation add the r values of the individual layers. The higher the insulation r value the greater the insulating power. Achieving greater r values in attics the higher the r value the better the thermal performance of the insulation. Insulation is identified and labeled by r value.

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