Common insulating materials and forms.
Types of insulation and their r values.
For instance if you have a material with an r value of 12 attached to another material with an r value of 3 then both materials combined have an r value of 15.
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.
The maximum thermal performance or r value of insulation is very dependent on proper installation.
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.
Here are the installation methods from lowest to highest average r value per inch.
Cellulose as loose or pellet fibers fiberglass or rock wool are generally the types of material used in loose fill insulation.
The higher the r value the better the thermal performance of the insulation.
R value is a measurement of thermal resistance and measures the ability of heat to transfer from one side of an object to another.
Foam board or rigid foam.
Insulation blankets batts and rolls spray foam insulation.
Insulation level are specified by r value.
Recommended home insulation r values.
Homeowners can install.
Blown in or loose fill insulation.
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.
R value is a measure of insulation s ability to resist heat traveling through it.
Batt and roll insulation.
