How Much Isolation Isolation Do You Really Need?


Is your house isolated properly?

Probably not, at least according to the North American Isolation Manufacturing Association or NAIMA. The organization found that by 2015, 90 percent of isolated homes are not isolated enough.

What does this mean? As a homeowner, your home may be too hot or cold. Moreover, your energy bill may be too expensive.

As you pass by your house and reevaluate your isolation situation, you may wonder how much of the loft insulation you really need?

The answers vary. We will explain the conditions that determine the amount of attic insulation that is right for your home.

Age of home
How old is your house?

If you bought a house shortly after it was built, you may not need to add as much insulation as possible. The change is at home 10 years and over. This requires a heavier insulation layer.

If not, as mentioned, you waste precious money every month. By isolating, you can reduce the use of air conditioning and heating.

In addition to the age of your home, your location is also important in determining how much insulation the attic you need.

Every state in the country (and some outside the United States) gets R.

According to International Energy Conservation Code or IECC and U.S. Department of Energy or DOE, this R value is divided into eight uninsulated loft zones:

Zone 1, which is R30 to R49 and covers the Virgin Islands, Puerto Rico, Guam, and Hawaii
Zone 2, which is R30 to R60 and covers Florida, parts of Georgia, parts of Louisiana, parts of Texas, parts of Arizona, and a small part of California
Zone 3, which is R30 to R60 and covers other parts of California, parts of Arizona, parts of New Mexico, parts of Texas, mostly Oklahoma and Arkansas, Mississippi, Alabama, South Carolina and parts of North Carolina
Zone 4, which is R38 to R60 and includes parts of Washington, parts of Oregon, parts of New Mexico, parts of Missouri, parts of Illinois, parts of Indiana, Kentucky, Virginia, Delaware, Maryland, New Jersey and Connecticut.
Zones 5 through 8, the R49 to R60 and cover all other states
Country of Isolation Your Attic is current
Walk through your attic and look for the following type of isolation. Each has an R value that determines the quality of the loft insulation.

Batts, made of fiberglass, have an R-3.2 x depth value
Granules, which may be made of pearlite or vermiculite, have an R value of 2.7 x depth
Gray gray or cellulose has a R value of 3.7 x depth
The stone wool fiber, which is black or gray, has an R value of 2.8 x depth
Loose fibers, which may be pink or slightly yellow, have a value of R 2.5 x depth
Now that you know more about the insulation requirements of the attic, it’s time to make a decision. Does your attic need to be re-insulated?

When choosing an isolation company, look for who has a long record of services in your area. It is also best if they provide different types of insulation, such as spraying spray insulation or spray foam insulation.
