Cellulose Insulation R Value Calculator

Input depth of existing blown in insulation in inches.

Cellulose insulation r value calculator.

As a benchmark one inch of solid wood has an r value of 1. R means resistance to heat flow. 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.

Inches more and more. The higher the r value the greater the insulating power. Click the button to calculate the depth in inches and pounds of total insulation required for this job. Click the button to calculate the depth in inches and pounds of total insulation required for this job.

Use this insulation savings calculator to measure the financial impact of increasing your insulation performance. This chart shows the r value of this insulation. A higher insulation r value usually means a higher price point as well. For every type and material of insulation check the r value per inch of thickness that the manufacturer has listed.

There are other factors to consider. Estimated depth of current insulation. This calculator is to be used as an estimating tool only. Typically a higher insulation r rating means better climate control and better energy efficiency for your home.

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. Square feet of house or area to be insulated current and desired r value for insulation and type and cost of your energy. Compare insulating r values before you buy. 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.

Input length width and desired r value of the area to be insulated. This calculator is to be used as an estimating tool only. What type of insulation do you currently have. Click the button to calculate the approximate r value for this job.

Length 10 ft width 6 feet bag coverage 16 5 cubic ft r value per 1 3 6 required r val. Enter your data into the fields where indicated. 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. Input length width and desired r value of the area to be insulated.
