How much does it cost to blow in insulation?
You can expect to pay $900-$3,000 in materials and labor for blown-in insulation. If you choose to install blown-in insulation yourself, it will cost roughly $1,300 for the material and blower rental. There is an additional cost for removing old insulation if need be, and that costs between $1 and $2 per square foot.
What is the price of blown insulation?
It comes in several materials and can be added in varying thicknesses and densities, leading to a wide range of costs. The national average cost for adding blown-in insulation to a home is $3,000 to $7,000. Most people pay around $5,000 to fill wall cavities and the attic with cellulose insulation in a 2,000 sq.ft. home with a 2-car garage.
Does cellulose insulation go bad?
There's a belief that it will last as long as your house stands and that it is more effective than other types of insulation. However, there's a disclaimer. It will only last the lifetime of your home with proper insulation installation and regular maintenance. .
Can I install cellulose insulation without a blower?
Since cellulose insulation is compressively packaged you cannot install it without using a blowing machine. I do not recommend trying to do this by hand. "A few bags" may not qualify you for loan of a machine, but you can certainly rent one from a big box home center or an equiment rental service.

Do mice like cellulose insulation?
Cellulose insulation is a deterrent for mice and other types of pests. Pests prefer solid materials where they can burrow and nest. The dry composition of the insulation makes it difficult for most pests and mice to survive.
Will cellulose insulation mold?
Mold growth sets in: Thanks to its chemical treatment, mold doesn't grow on cellulose insulation. However, water-soaked fibers sit right against wood studs and drywall, which are susceptible to mold growth.
Is cellulose wall insulation worth it?
When done right, dense-packed cellulose is a highly efficient option for insulating exterior walls. It insulates as well if not better than the average batt (R3. 5-3.8/inch), and slows air flow through walls making your house cheaper and easier to heat and cool.
Which is better cellulose or fiberglass insulation?
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.
Does cellulose insulation need a vapor barrier?
A common misconception is that vapor barriers are required in all insulation installations. With Modern's Cellulose insulation, a vapor barrier is not recommended except in very cold weather or high moisture areas such as spas or pool buildings.
Does cellulose insulation attract termites?
Cellulose insulation uses borate fire retardants, which are unattractive to insects. So the product would not attract termites or any other insect. In fact, there are even some cellulose insulation brands available that are certified pest control products.

How deep should loose fill insulation be?
When blown into attics and wall spaces, loose-fill fiberglass offers an average R-2.5 thermal value per inch (the higher the number, the greater the insulating effect). You'd need a thickness of about 7.5 inches of insulation to match the insulating value of a batt of R-19 insulation (R-19 is a common batt value).

What is the R factor of fiber insulation?
The R-factor of fiber insulation follows an inverse "U" curve. As density increases, R-factor increases--up to a point. Dense packed cellulose insulation at 3.0 to 3.5 pcf--typical installed density in closed cavities--has an R-factor of 3.9 or 4.0, compared with 3.7 or 3.8 at settled density. Fiber glass at 2.2 to 2.5 pcf may have an R-factor in excess of 4.0, compared with 2.2 to 3.1 at design density. At some point the curves for both materials turn around and R-factor decreases with greater density. For cellulose that seems to be somewhere between 3.5 and 4.0.

Does insulation need air pockets?
As many have said, insulation requires air pockets within the material to have any R value. Those pockets effectively trap temperate air and reduce thermal transfer on opposite sides of the material. So yes, it HAS to be fluffed from it's vac-packed shipping form to be of any use and this will also make the material go further.
Does blowing insulation in a house reduce its value?
That type of insulation comes highly compressed, blowing it in will get separated and back to its original size. Without decompressing it the insulation won't have any air space, so less insulation value. You will end up using more insulation material and spending more money for less insulation capability.
Can you blow a wall without a blower?
Additionally without a blower you'll have trouble getting it actually dispersed into your wall in the first place. Blowing it in will get it spread out evenly, simply pouring it in will likely leave large gaps, meaning less actual insulating.

Is fiberglass insulation eco friendly?
If you use other home insulation alternatives such as fiberglass, it is not as eco-friendly as cellulose insulation. It has fine particles that may irritate your skin. Not to mention, inhaling them can cause health problems as well. Plus, you need to cut it into small sizes to fit tight corners, penetrations, and irregular spaces that leave tiny gaps. The gaps may increase the heat and cold transmission.
Is cellulose insulation fire retardant?

Layering on sweaters is one way to stay warm in a poorly insulated house, but while you’re bundling up, your furnace is still working overtime to ward off the chill and your home’s water pipes could be at risk of freezing and breaking. Today’s building codes require a minimum amount of insulation in walls and attics, but older homes were often under-insulated, so for many owners of such homes, the answer is blown-in insulation: tiny pieces of material (think confetti) that is literally blown into your walls and above your ceiling via a long hose. Keep reading to find out if blown-in insulation might be your solution to comfier conditions and lower energy bills.
What is rock wool made of?
Rock Wool: Also called “mineral wool,” this type of blown-in insulation is made from blast furnace slag (a byproduct of firing iron and iron ore). The slag is heated, combined with other minerals, and then spun into an airy product that resembles the texture of raw sheep’s wool.
What is batt insulation?
During new construction, batt insulation—thick strips of spun fiberglass or a paper-based product—is cut to fit between wall studs and ceiling joists before wallboard is put up to increase insulation values .
Does blown in insulation reduce thermal resistance?
After a few years, blown-in insulation tends to settle downward by a few inches, which slightly reduces its overall thermal resist ance (known as R-value), because it leaves a small section at the top of the stud space uninsulated. Blowing in additional insulation is an option, but most homeowners forego this step because it’s such a small area.
Is rock wool fire resistant?
Despite its high price point, due to its excellent fire resistance, rock wool is often called for in areas subject to fire codes , such as a connecting wall between a house and an attached garage, or in the floor between a garage and a FROG room (finished room over garage).
What is cellulose insulation?
Cellulose insulation is the oldest form of home insulation available on the market today. It can be installed as either a loose-fill or blown-in insulation.
What happens if you use cellulose insulation in the attic?
If you use loose-fill cellulose insulation on the attic floor, the airflow from the vents will cause the material to drift, leaving spaces in the attic uninsulated. Also, as that outside air moves through the cellulose, pollen, bacteria, and mold spores can cling to it.
What is the most difficult material to work with?
Cellulose insulation is one of the most difficult materials to work with if you need new wiring or alterations to the home. When a puncture is made in the cavity where the cellulose has been installed, the material just pours out of the hole.

Why does cellulose get wet?
Some cellulose insulation materials can absorb up to 130 percent water by weight. Cellulose can get wet due to condensation, lack of air seal, or leaks in the home. The material dries very slowly after it absorbs the water, which causes it to deteriorate and settle.
How much does cellulose settle?
Modern cellulose settles up to 20 percent, according to House Energy.
What to do if insulation gets wet?
If the material becomes wet, your best option will be to replace it. Another option is to choose an insulation material that doesn’t retain water.
