Is R60 attic insulation worth it?

Recommended R-Value Varies by State

You need exactly as much as the area you live in determines. Here, where temps get pretty hot for much of the year, attics should have from R30 to R60 (average is R38). Those living up north want anything from R49 to R60. This helps insulate against the extreme cold weather.

How many inches of insulation do I need for a R60?

If you have approximately 6" of existing insulation, you'll need to add an additional 17" to reach R-60. If you have approximately 10" of existing insulation, you'll need to add an additional 13" to reach R-60. If you have no insulation, you'll need 23" to reach R-60.

Is upgrading attic insulation worth it?

Installing attic insulation this winter is a worthwhile long-term investment because it can significantly decrease your heating bills. As an added benefit, when the hot D.C. temperatures come back, the attic insulation will also minimize your air conditioning bills.

What is a good R-value for attic insulation?

R-Value is a measure of insulation's ability to resist heat flow. The higher the R-Value, the better the thermal performance of the insulation. The recommended level for most attics is to insulate to R-38 or about 10 to 14 inches, depending on insulation type.

What is the most effective attic insulation?

Spray Foam Attic Insulation

Spray foam offers the best attic insulation performance available. Choose from two types: closed-cell and open-cell, aka 2-pound and ½-pound, respectively. They sport insulation values of approximately R-6.5 and R-3.6 per inch, respectively.

Can you have too much insulation in your attic?

It's possible to over-insulate an attic as too much will cause moisture buildup and eventually result in mold. Eventually, adding more insulation leads to diminishing returns in trapping heat as well.

Should I remove old attic insulation before adding new?

Expert contractors that specialize in insulation advise that removing old fiberglass insulation is best before installing new cellulose insulation because of possible mildew, mold, or rodent excrement.

Does insulation lose R-value over time?

Yes. Cellulose insulation does lose its R-value when it is compressed. The amount of loss depends on how much insulation is decompressed but typically ranges anywhere from 15% to 20% of its initial value.

How often should you insulate your attic?

How often should attic insulation be changed? Even though attic insulation is said to last anywhere from 80 years to 100 years, it does lose effectiveness as its ages. Insulation experts recommend replacing after 15 years to assure it is doing the job you need it to.

How can I improve attic insulation?

Will insulating my attic make my house warmer?

The short answer, yes, insulating the attic is an effective way to keep your home cooler during the summer months. While it's a given that the insulation in your attic will keep the home warmer during the winter, it isn't immediately obvious that insulation can also help to keep the home comfortable during the summer.

Is blown in attic insulation worth it?

Unless your home is relatively new, you will almost certainly benefit from installing blown insulation in your attic. It will make your home a more comfortable place to be in summer and winter, decrease the cost of your energy bills, and increase the value of your home.

How do I know if my house needs more insulation?

How thick is R60 blown?

R 60: Thickness that oscillates between 19 and 22 inches. R 70: Thickness that oscillates between 22 and 25 inches.

What does R60 insulation mean?

On average, the higher the R-value, the more resistant the material, so if you have a material that's rated R60, it will be more resistant to heat than a material that's rated R30.

Is blown insulation better than rolled?

The Differences Between Blown-in and Rolled Insulation

In terms of R-value, they tend to be equal, although you can choose rolled insulation with varying R-values depending on your needs and your budget. The lower the R-value is, the less effective it will be as insulation – although it will be cheaper as well.

Is blown-in insulation better?

Finally, while blown insulation is much more consistent and has a much lower chance of failure, the R-value of this insulation will typically have a higher R-value due to installation quality differences. Contact the experts at Balanced Comfort to find out which insulation is right for you!

Is blown-in insulation better than fiberglass?

At 3.5 per inch of material, the R-value of blown-in cellulose is 23% better per inch than fiberglass batts! According to research done at the Oak Ridge National Lab, fiberglass loses up to 50% of its R-value in very cold conditions; making cellulose a better choice for homes in northern climates.

Should black insulation be replaced?

You should change your insulation if it has turned black and have it replaced so that it won't cause any damage. Insulation that has turned black will likely be less effective.

Do you need to replace insulation after mice?

Rodents, in particular, pose a serious risk to the effectiveness of your attic insulation. If a rodent infestation occurs, it can become important to contact insulation companies to remove your current insulation that is in your attic floor and replace it with new insulation.

Does doubling insulation Double R-value?

Doubling the thickness of insulation will double the insulation's R-value, cutting heat loss in half. Each time the insulation layer is doubled in thickness, this rule applies.

Is it worth replacing old fiberglass insulation?

Fiberglass insulation is a popular choice because it is both effective and cost-effective. Unless damaged, it can last 80 to 100 years in most houses before it needs to be replaced.

Can old insulation make you sick?

Attic insulation is an essential part of our homes, but dirty, old, poorly installed insulation can make us sick. While insulation may not be something you usually spend your time worrying about on a day-to-day basis, it's a worthwhile question to ask.

What insulation has the highest R-value?

Vacuum insulated panels have the highest R-value, approximately R-45 (in U.S. units) per inch; aerogel has the next highest R-value (about R-10 to R-30 per inch), followed by polyurethane (PUR) and phenolic foam insulations with R-7 per inch.

Is it worth insulating an old house?

It's worth insulating an old house because it'll help you save on electricity bills down the road. A home without insulation drains the heating and cooling elements of power, making them work overtime. By adding insulation, you'll prevent your home from leaking air and energy.
