Batt and roll insulation.
Types of insulation and their r values.
Blown cellulose carries an insulation r value of 3 7 and fiberglass holds an r value of 3 14.
The table below shows what levels of insulation are cost effective for different climates and.
R value is a measure of insulation s ability to resist heat traveling through it.
The higher the r value the better the thermal performance of the insulation.
Here are the installation methods from lowest to highest average r value per inch.
Homeowners can install.
The maximum thermal performance or r value of insulation is very dependent on proper installation.
Recommended home insulation r values.
Foam board or rigid foam.
R value is a measurement of thermal resistance and measures the ability of heat to transfer from one side of an object to another.
Fiberglass batts for standard 2 4 walls are now available in low medium and high density products that range from r 11 to r 15.
Insulation level are specified by r value.
Common insulating materials and forms.
There are a number of different materials such as fiberglass and cellulose as well as a number of different forms such as batting and blown in.
Insulation blankets batts and rolls spray foam insulation.
The common denominator among varieties of insulation is the r value.
In simple terms r values measure the effectiveness of insulation and a higher number represents more effective insulation.
Blown in or loose fill insulation.
