Blown In Attic Insulation Depth

Some installations can yield a higher r value than traditional batt insulation for the same thickness and can fill even the smallest cavities creating an effective air barrier.

Blown in attic insulation depth.

Blowing insulation into walls is best left to the pros because it involves drilling into stud spaces that may contain electrical. In temperate coastal areas such as zone 3 attic insulation of at least r30 up to a maximum of r60 is recommended. Blowing the insulation should take less than 1 5. Types of blown in insulation the two commonly used types of blown in attic insulation are cellulose and fiberglass.

Click the button to calculate the approximate r value for this job. Foam in place insulation can be blown into walls on attic surfaces or under floors to insulate and reduce air leakage. These include the type depth and density of the insulation. Having the correct amount of attic insulation can help you maintain a comfortable temperature throughout your home and help save money on your energy bills plus prevent major issues like ice dams in the winter.

Achieving greater r values in attics the higher the r value the better the thermal performance of the insulation. Handy homeowners can install blown in insulation in the attic. R value is a measure of insulation s ability to resist heat traveling through it. For loose fill cellulose this translates to a total depth ranging from 8 inches.

Input depth of existing blown in insulation in inches. If you think you re among the 90 of us homes that are under insulated 1 performing a simple insulation inspection will help you determine your insulation needs. Input length width and desired r value of the area to be insulated. You can use the small pressurized cans of foam.

This calculator is to be used as an estimating tool only. The higher the r value the better the thermal performance of the insulation. Atticat expanding blown in insulation is designed for your attic insulation project in new or existing homes. The specially designed atticat machine conditions the insulation by adding millions of tiny air pockets that give the material its insulating power and energy saving r value over time.

Find your zone on the map and then use the chart to determine the level of insulation you need to properly insulate your attic walls floors and crawlspaces. Insulation level are specified by r value.
