Blown In Attic Insulation Depth

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

Blown in attic insulation depth.

Foam in place insulation can be blown into walls on attic surfaces or under floors to insulate and reduce air leakage. Click the button to calculate the approximate r value for this job. 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. Types of blown in insulation the two commonly used types of blown in attic insulation are cellulose and fiberglass.

Inspecting attic insulation there are several factors to consider when inspecting loose fill blown in attic insulation. Blowing the insulation should take less than 1 5. 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. This calculator is to be used as an estimating tool only.

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. Input depth of existing blown in insulation in inches. Insulation level are specified by r value. Achieving greater r values in attics the higher the r value the better the thermal performance of the insulation.

R value is a measure of insulation s ability to resist heat traveling through it. This calculator is to be used as an estimating tool only. Atticat expanding blown in insulation is designed for your attic insulation project in new or existing homes. The higher the r value the better the thermal performance of the insulation.

Handy homeowners can install blown in insulation in the attic. In temperate coastal areas such as zone 3 attic insulation of at least r30 up to a maximum of r60 is recommended. 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. You can use the small pressurized cans of foam.

Blowing insulation into walls is best left to the pros because it involves drilling into stud spaces that may contain electrical. Input length width and desired r value of the area to be insulated. For loose fill cellulose this translates to a total depth ranging from 8 inches.
