Cellulose Insulation R Value Calculator

Square feet of house or area to be insulated current and desired r value for insulation and type and cost of your energy.

Cellulose insulation r value calculator.

This chart shows the r value of this insulation. In comparison an inch of blown fiberglass insulation has an r value of 3 1 3 4 and an inch of blown cellulose in an attic has an r value of 3 2 3 7 along with knowing the r value of a particular insulation it is also important to calculate the r value of a total system. Length 10 ft width 6 feet bag coverage 16 5 cubic ft r value per 1 3 6 required r val. Input length width and desired r value of the area to be insulated.

Click the button to calculate the depth in inches and pounds of total insulation required for this job. This calculator is to be used as an estimating tool only. Compare insulating r values before you buy. The higher the r value the greater the insulating power.

Estimated depth of current insulation. 12 area 10 6 60 square ft required depth to achieve r value needed r 12 r 3 6 3 3 inches volume needed 60sq ft 0 275 3 3 12 converting to decimal ft 16 5 cubic feet you would need one bag in this case. Click the button to calculate the approximate r value for this job. Inches more and more.

R means resistance to heat flow. Enter your data into the fields where indicated. Greenfiber insulation calculator easy to follow steps for calculating the perfect amount of insulation needed for your project. However like other loose fill insulation it also has a tendency to settle over time reducing its r value and its ability to prevent air movement.

The amount of the insulation you need depends on the climate you live in. This calculator is to be used as an estimating tool only. Input depth of existing blown in insulation in inches. What type of insulation do you currently have.

Input length width and desired r value of the area to be insulated. A higher insulation r value usually means a higher price point as well. Click the button to calculate the depth in inches and pounds of total insulation required for this job. Typically a higher insulation r rating means better climate control and better energy efficiency for your home.

This calculator is to be used as an estimating tool only. There are other factors to consider. Current r value target r value project size in ft 2 bags of greenfiber already have insulation. As a benchmark one inch of solid wood has an r value of 1.

As a loose fill insulation cellulose provides high insulating values represented by its higher r value and it creates a good barrier against air leaks and infiltration.
