Types Of Insulation And Their R Values

The table below shows what levels of insulation are cost effective for different climates and.

Types of insulation and their r values.

The common denominator among varieties of insulation is the r value. Insulation blankets batts and rolls spray foam insulation. 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 level are specified by r value.

Batt and roll 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. In simple terms r values measure the effectiveness of insulation and a higher number represents more effective insulation. While wall insulation is limited by the width of the studs different materials provide higher or lower r values.

Common insulating materials and forms. The higher the r value the better the thermal performance of the insulation. Blown in or loose fill insulation. Recommended home insulation 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. R value is a measurement of thermal resistance and measures the ability of heat to transfer from one side of an object to another. R value is a measure of insulation s ability to resist heat traveling through it. Homeowners can install.

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.
