How Many Inches Of Blown Insulation Should Be In My Attic?
According to the Department of Energy, most homes should have insulation levels of R-38 in the attic. However, if your home was built before 1980 or has air leaks in the attic, you may need more insulation.
In order to figure out how much insulation you need, you’ll need to measure the thickness of the insulation in your attic. You should add at least 12 inches of blown-in insulation if you don’t have any insulation.
How much blown insulation should be in the attic? How much blown insulation should be in the attic? Blown-in insulation is a perfect way to maximize the insulation in your attic. The most important factor in blown insulation is the depth of the insulation. The Department of Energy recommends 12 to 16 inches of insulation for an attic.
Insulation comes in different thicknesses, so purchasing the correct thickness for your attic is important. The R-value of the insulation will tell you how much the insulation can insulate.
The higher the R-value, the more insulation the product has. The R-value of fiberglass insulation is 3.5 per inch, so you would need at least R-49 to achieve the recommended depth.
How much does it cost to have insulation blown-in attic?
Blowing insulation is not cheap, you can expect to pay upwards of $1.50 per square foot. However, the long-term savings on your energy bill will make the investment worth it.

How long does blown-in attic insulation last?
Blown-in attic insulation is a type of insulation that is made of small pieces of fiberglass. It is blown into the attic using a machine. Blown-in insulation is a great option for homeowners who want to improve the insulation in their homes.
One of the main benefits of blown-in attic insulation is that it lasts a long time. It can last for up to 20 years, which is much longer than other types of insulation. This is because the small fiberglass pieces can move around and fill in any gaps or cracks in the attic.
Another benefit of blown-in attic insulation is that it effectively prevents heat loss. This is because the small fiberglass pieces create a layer of insulation that helps keep the heat in. This can help save homeowners money on their energy bills.
Blown-in attic insulation is a great option for homeowners who want to improve the insulation in their homes. It is long-lasting and effective at preventing heat loss.
How do I remove blown in insulation from my attic?
Removing blown-in attic insulation can be a daunting task, but with the right tools and knowledge, it can be done relatively easily.
The first step is to assess the amount of blown-in insulation in the attic. If there is more than a foot of insulation, it is best to leave it in place and cover it with a vapor barrier. If there is less than a foot of insulation, it can be removed without covering the area with a vapor barrier.
To remove the insulation, start by using a blower to push it towards the eaves of the attic. Once it is in the eaves, use a metal rake to pull the insulation out. Be sure to wear a dust mask to avoid breathing in the insulation.
What is the R-value of blown-in attic insulation?
The R-value of blown-in attic insulation varies depending on the type of insulation used. Blown-in fiberglass has an R-value of 2.2 to 2.7 per inch, while cellulose insulation has an R-value of 3.1 – 3.8 per inch.
The durability of this material will depend on a number of factors, including the quality of the insulation, the climate, and the manner in which it is installed. However, it is generally estimated that blown-in insulation can last for up to 15 years.
Is blown-in or batt insulation better for attic?
When choosing insulation for your attic, there are a few things you need to consider: the climate you live in, the size of your attic, and the type of roof you have.
Blown-in insulation is a good option if you live in a cold climate, as it can help keep your attic warm. Batt insulation is a good option if you live in a warm climate, as it can help keep your attic cool.
The size of your attic is also important to consider when choosing insulation. If your attic is small, blown-in insulation may be a better option, as batt insulation can take up a lot of space.
If your attic is large, batt insulation may be a better option, as blown-in insulation may not be able to cover the entire attic.
The type of roof you have is also important to consider when choosing insulation. If you have a flat roof, blown-in insulation may be a better option, as batt insulation can slide off a flat roof.
If you have a sloped roof, batt insulation may be a better option, as blown-in insulation can be blown off a sloped roof.
There is no definitive answer when it comes to blown-in or batt insulation for attic, as the best choice depends on a variety of factors.
However, blown-in insulation is typically better at filling in gaps and ensuring even coverage, making it a better choice for older homes with less uniform insulation.
Is blown in attic insulation flammable?
Blown in attic insulation is made of fiberglass or cellulose. While it is not technically flammable, it will burn if it comes into contact with a flame. This is why it is important to have attic insulation in addition to a smoke detector and fire extinguisher in your home.
Can you walk in an attic with blown insulation?
You should never walk in an attic with blown insulation. It is a dangerous and potentially life-threatening situation. Fiberglass or cellulose can become airborne and cause respiratory problems. It can also damage your skin and eyes.
