Attic Insulation R Value Map

Your home s r value score will guide you toward the type of insulation you need.

Attic insulation r value map.

Install insulation with the proper r value. Achieving greater r values in attics the higher the r value the better the thermal performance of the insulation. R stands for resistance to heat flow. How do you figure out r value.

When calculating the r value of a multilayered installation add the r values of the individual layers. In particularly cold climates you might go up to r 60. The table below shows what levels of insulation are cost effective for different climates and. Installing more insulation in your home increases the r value and the resistance to heat flow.

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. Colder climates will typically require a higher r value for even greater thermal. The higher r value the better insulation performance.

You ll see insulation r values indicated on product packaging and often on the product itself. In general an attic s r value should be between r 30 and r 49. R value requirements are different based on your location. R value refers to the insulation s ability to resist heat flow.

The higher the insulation r value the greater the insulating power. The r value of some insulations also depends on temperature aging and moisture accumulation. 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. R value is a measure of insulation s ability to resist heat traveling through it.

The greater the r value the greater the insulating performance. The higher the r value the better the thermal performance of the insulation.
